Description

Electronic equipment having an antenna

The present invention relates to an electronic device having a broadband antenna. More particularly, it relates to a communication relay device having a plurality of antennas.

Electronic devices may be divided into mobile/portable terminals and stationary terminals depending on whether they can be moved. Again, the electronic device can be divided into a handheld terminal and a vehicle mounted terminal according to whether the user can directly carry the electronic device.

The functions of electronic devices are diversifying. For example, there are functions for data and voice communication, photo and video shooting through a camera, voice recording, music file playback through a speaker system, and an image or video output to the display unit. Some terminals add an electronic game play function or perform a multimedia player function. In particular, recent mobile terminals can receive multicast signals that provide broadcast and visual content such as video or television programs.

In addition, it is expected that a wireless communication system using 5G communication technology will be commercialized in the future to provide various services. Meanwhile, some of the LTE frequency bands may be allocated to provide 5G communication services.

In this regard, the mobile terminal may be configured to provide 5G communication services in various frequency bands. Recently, attempts have been made to provide a 5G communication service using the Sub6 band below the 6GHz band.

Here, the 4G base station and the 5G base station may have a Non-Stand-Alone (NSA) structure. For example, the 4G base station and the 5G base station may be a co-located structure disposed at the same location in a cell. Alternatively, the 5G base station may be disposed in a stand-alone (SA) structure at a location separate from the 4G base station.

The 5G wireless communication module 112 may transmit and receive a 5G signal with a 5G base station through a 5G mobile communication network. In this case, the 5G wireless communication module 112 may transmit one or more 5G transmission signals to the 5G base station. In addition, the 5G wireless communication module 112 may receive one or more 5G reception signals from the 5G base station.

In this case, the 5G frequency band may use the same band as the 4G frequency band, and this may be referred to as LTE re-farming. Meanwhile, as the 5G frequency band, the Sub6 band, which is a band of 6 GHz or less, may be used.

On the other hand, a millimeter wave (mmWave) band may be used as a 5G frequency band to perform broadband high-speed communication. When a millimeter wave (mmWave) band is used, the electronic device 100 may perform beam forming for communication coverage expansion with a base station.

Meanwhile, regardless of the 5G frequency band, the 5G communication system may support a larger number of Multi-Input Multi-Output (MIMO) in order to improve transmission speed. In this regard, Up-Link (UL) MIMO may be performed by a plurality of 5G transmission signals transmitted to the 5G base station. In addition, Down-Link (DL) MIMO may be performed by a plurality of 5G reception signals received from a 5G base station.

Meanwhile, the wireless communication unit 110 may be in a dual connectivity (DC) state with the 4G base station and the 5G base station through the 4G wireless communication module 111 and the 5G wireless communication module 112 . In this way, the dual connection with the 4G base station and the 5G base station may be referred to as EN-DC (EUTRAN NR DC). Here, EUTRAN is an Evolved Universal Telecommunication Radio Access Network, which means a 4G wireless communication system, and NR is New Radio, which means a 5G wireless communication system.

On the other hand, if the 4G base station and the 5G base station have a co-located structure, throughput improvement is possible through inter-CA (Carrier Aggregation). Therefore, the 4G base station and the 5G base station In the EN-DC state, the 4G reception signal and the 5G reception signal may be simultaneously received through the 4G wireless communication module 111 and the 5G wireless communication module 112 .

The short-distance communication module 114, between the electronic device 100 and a wireless communication system, between the electronic device 100 and another electronic device 100, or the electronic device 100 through wireless area networks (Wireless Area Networks) ) and a network in which another electronic device 100 or an external server is located may support wireless communication. The local area network may be a local area network (Wireless Personal Area Networks).

Meanwhile, short-range communication between electronic devices may be performed using the 4G wireless communication module 111 and the 5G wireless communication module 112 . In an embodiment, short-distance communication may be performed between electronic devices using a device-to-device (D2D) method without going through a base station.

On the other hand, for transmission speed improvement and communication system convergence (convergence), carrier aggregation (CA) using at least one of the 4G wireless communication module 111 and the 5G wireless communication module 112 and the Wi-Fi communication module 113 This can be done. In this regard, 4G + WiFi carrier aggregation (CA) may be performed using the 4G wireless communication module 111 and the Wi-Fi communication module 113 . Alternatively, 5G + WiFi carrier aggregation (CA) may be performed using the 5G wireless communication module 112 and the Wi-Fi communication module 113 .

The location information module 114 is a module for acquiring a location (or current location) of an electronic device, and a representative example thereof includes a Global Positioning System (GPS) module or a Wireless Fidelity (WiFi) module. For example, if the electronic device utilizes a GPS module, it may acquire the location of the electronic device by using a signal transmitted from a GPS satellite. As another example, if the electronic device utilizes the Wi-Fi module, the location of the electronic device may be acquired based on information of the Wi-Fi module and a wireless access point (AP) that transmits or receives a wireless signal. If necessary, the location information module 114 may perform any function of the other modules of the wireless communication unit 110 to obtain data on the location of the electronic device as a substitute or additionally. The location information module 114 is a module used to obtain the location (or current location) of the electronic device, and is not limited to a module that directly calculates or obtains the location of the electronic device.

Specifically, if the electronic device utilizes the 5G wireless communication module 112, it is possible to acquire the location of the electronic device based on the information of the 5G wireless communication module and the 5G base station that transmits or receives the wireless signal. In particular, since the 5G base station of the millimeter wave (mmWave) band is deployed in a small cell having a narrow coverage, it is advantageous to obtain the location of the electronic device.

The input unit 120 includes a camera 121 or an image input unit for inputting an image signal, a microphone 122 or an audio input unit for inputting an audio signal, and a user input unit 123 for receiving information from a user, for example, , a touch key, a push key, etc.).

The display unit 151 may implement a touch screen by forming a layer structure with the touch sensor or being formed integrally with the touch sensor. Such a touch screen may function as the user input unit 123 providing an input interface between the electronic device 100 and the user, and may provide an output interface between the electronic device 100 and the user.

The interface unit 160 serves as a passage with various types of external devices connected to the electronic device 100 .

Hereinafter, a structure of a multiple transmission system according to the present invention and an electronic device having the same, in particular, a power amplifier in a heterogeneous radio system and embodiments related to an electronic device having the same will be described with reference to the accompanying drawings. It is apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

2 illustrates a configuration of a wireless communication unit of an electronic device operable in a plurality of wireless communication systems according to the present invention. Referring to FIG. 2 , the electronic device includes a first power amplifier 210 , a second power amplifier 220 , and an RFIC 250 . Also, the electronic device may further include a modem 400 and an application processor (AP) 450 . Here, the modem 400 and the application processor AP 450 may be physically implemented on a single chip, and may be implemented in a logically and functionally separated form. However, the present invention is not limited thereto and may be implemented in the form of physically separated chips depending on the application.

Meanwhile, the electronic device includes a plurality of low noise amplifiers (LNAs) 310 to 340 in the receiver. Here, the first power amplifier 210 , the second power amplifier 220 , the controller 250 , and the plurality of low-noise amplifiers 310 to 340 are all operable in the first communication system and the second communication system. In this case, the first communication system and the second communication system may be a 4G communication system and a 5G communication system, respectively.

As shown in FIG. 2 , the RFIC 250 may be configured as a 4G/5G integrated type, but is not limited thereto and may be configured as a 4G/5G separate type according to an application. When the RFIC 250 is configured as a 4G/5G integrated type, it is advantageous in terms of synchronization between 4G/5G circuits, as well as the advantage that control signaling by the modem 400 can be simplified.

Meanwhile, when the RFIC 250 is configured as a 4G/5G separate type, it may be referred to as a 4G RFIC and a 5G RFIC, respectively. In particular, when the difference between the 5G band and the 4G band is large, such as when the 5G band is configured as a millimeter wave band, the RFIC 250 may be configured as a 4G/5G separate type. As such, when the RFIC 250 is configured as a 4G/5G separate type, there is an advantage that RF characteristics can be optimized for each of the 4G band and the 5G band.

Meanwhile, even when the RFIC 250 is configured as a 4G/5G separate type, the 4G RFIC and the 5G RFIC are logically and functionally separated, and it is also possible to be physically implemented on a single chip.

Meanwhile, the application processor (AP) 450 is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP) 450 may control the operation of each component of the electronic device through the modem 400 .

For example, the modem 400 may be controlled through a power management IC (PMIC) for low power operation of the electronic device. Accordingly, the modem 400 may operate the power circuits of the transmitter and the receiver in the low power mode through the RFIC 250 .

In this regard, when it is determined that the electronic device is in an idle mode, the application processor (AP) 450 may control the RFIC 250 through the modem 400 as follows. For example, if the electronic device is in an idle mode, at least one of the first and second power amplifiers 110 and 120 operates in a low power mode or is turned off via RFIC through the modem 400 . 250 can be controlled.

According to another embodiment, when the electronic device is in a low battery mode, the application processor (AP) 450 may control the modem 400 to provide wireless communication capable of low power communication. For example, when the electronic device is connected to a plurality of entities among a 4G base station, a 5G base station, and an access point, the application processor (AP) 450 may control the modem 400 to enable wireless communication with the lowest power. Accordingly, the application processor (AP) 450 may control the modem 400 and the RFIC 250 to perform short-range communication using only the short-range communication module 113 even at sacrificing throughput.

According to another embodiment, when the remaining battery level of the electronic device is equal to or greater than a threshold, the modem 400 may be controlled to select an optimal wireless interface. For example, the application processor (AP) 450 may control the modem 400 to receive through both the 4G base station and the 5G base station according to the remaining battery level and available radio resource information. In this case, the application processor (AP) 450 may receive the remaining battery level information from the PMIC and the available radio resource information from the modem 400 . Accordingly, if the remaining battery level and available radio resources are sufficient, the application processor (AP) 450 may control the modem 400 and the RFIC 250 to receive through both the 4G base station and the 5G base station.

Meanwhile, the multi-transceiving system of FIG. 2 may integrate a transmitter and a receiver of each radio system into one transceiver. Accordingly, there is an advantage that a circuit part integrating two types of system signals in the RF front-end can be removed.

In addition, since the front-end components can be controlled by the integrated transceiver, the front-end components can be more efficiently integrated than when the transmission/reception system is separated for each communication system.

In addition, when each communication system is separated, it is impossible to control other communication systems as necessary, or efficient resource allocation is impossible because the system delay is increased. On the other hand, the multi-transmission/reception system as shown in FIG. 2 has the advantage that it is possible to control other communication systems as necessary, and thus system delay can be minimized, so that efficient resource allocation is possible.

Meanwhile, the first power amplifier 210 and the second power amplifier 220 may operate in at least one of the first and second communication systems. In this regard, when the 5G communication system operates in the 4G band or the Sub6 band, the first and second power amplifiers 220 may operate in both the first and second communication systems.

On the other hand, when the 5G communication system operates in the millimeter wave (mmWave) band, one of the first and second power amplifiers 210 and 220 operates in the 4G band, and the other operates in the millimeter wave band. have.

Meanwhile, by integrating the transceiver and the receiving unit, two different wireless communication systems can be implemented with one antenna by using an antenna for both transmitting and receiving. In this case, 4x4 MIMO can be implemented using four antennas as shown in FIG. 2 . In this case, 4x4 DL MIMO may be performed through the downlink (DL).

Meanwhile, if the 5G band is the Sub6 band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in both the 4G band and the 5G band. On the other hand, if the 5G band is a millimeter wave (mmWave) band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in any one of the 4G band and the 5G band. In this case, if the 5G band is a millimeter wave (mmWave) band, each of a plurality of separate antennas may be configured as an array antenna in the millimeter wave band.

Meanwhile, 2x2 MIMO implementation is possible using two antennas connected to the first power amplifier 210 and the second power amplifier 220 among the four antennas. In this case, 2x2 UL MIMO (2 Tx) may be performed through the uplink (UL). Alternatively, it is not limited to 2x2 UL MIMO, and may be implemented with 1 Tx or 4 Tx. In this case, when the 5G communication system is implemented as 1 Tx, only one of the first and second power amplifiers 210 and 220 may operate in the 5G band. On the other hand, when the 5G communication system is implemented as 4Tx, an additional power amplifier operating in the 5G band may be further provided. Alternatively, a transmission signal may be branched in each of one or two transmission paths, and the branched transmission signal may be connected to a plurality of antennas.

On the other hand, since a switch-type splitter or a power divider is built inside the RFIC corresponding to the RFIC 250, there is no need for a separate component to be disposed outside, thereby improving component mountability. can Specifically, by using a single pole double throw (SPDT) type switch inside the RFIC corresponding to the controller 250 , it is possible to select the transmitter (TX) of two different communication systems.

In addition, the electronic device capable of operating in a plurality of wireless communication systems according to the present invention may further include a duplexer 231 , a filter 232 , and a switch 233 .

The duplexer 231 is configured to mutually separate signals of a transmission band and a reception band. At this time, the signals of the transmission band transmitted through the first and second power amplifiers 210 and 220 are applied to the antennas ANT1 and ANT4 through the first output port of the duplexer 231 . On the other hand, signals of the reception band received through the antennas ANT1 and ANT4 are received by the low noise amplifiers 310 and 340 through the second output port of the duplexer 231 .

The filter 232 may be configured to pass a signal of a transmission band or a reception band and block a signal of the remaining band. In this case, the filter 232 may include a transmit filter connected to a first output port of the duplexer 231 and a receive filter connected to a second output port of the duplexer 231 . Alternatively, the filter 232 may be configured to pass only a signal of a transmission band or only a signal of a reception band according to the control signal.

The switch 233 is configured to transmit either only a transmit signal or a receive signal. In an embodiment of the present invention, the switch 233 may be configured in a single pole double throw (SPDT) type to separate a transmission signal and a reception signal in a time division multiplexing (TDD) method. In this case, the transmission signal and the reception signal are signals of the same frequency band, and accordingly, the duplexer 231 may be implemented in the form of a circulator.

On the other hand, in another embodiment of the present invention, the switch 233 is also applicable to a frequency division multiplexing (FDD: Time Division Duplex) scheme. In this case, the switch 233 may be configured in a double pole double throw (DPDT) type to connect or block a transmission signal and a reception signal, respectively. Meanwhile, since the transmission signal and the reception signal can be separated by the duplexer 231 , the switch 233 is not necessarily required.

Meanwhile, the electronic device according to the present invention may further include a modem 400 corresponding to a control unit. In this case, the RFIC 250 and the modem 400 may be referred to as a first controller (or first processor) and a second controller (second processor), respectively. Meanwhile, the RFIC 250 and the modem 400 may be implemented as physically separate circuits. Alternatively, the RFIC 250 and the modem 400 may be physically or logically divided into one circuit.

The modem 400 may control and process signals for transmission and reception of signals through different communication systems through the RFIC 250 . The modem 400 may be obtained through control information received from the 4G base station and/or the 5G base station. Here, the control information may be received through a physical downlink control channel (PDCCH), but is not limited thereto.

The modem 400 may control the RFIC 250 to transmit and/or receive signals through the first communication system and/or the second communication system in a specific time and frequency resource. Accordingly, the RFIC 250 may control transmission circuits including the first and second power amplifiers 210 and 220 to transmit a 4G signal or a 5G signal in a specific time period. In addition, the RFIC 250 may control receiving circuits including the first to fourth low-noise amplifiers 310 to 340 to receive a 4G signal or a 5G signal in a specific time period.

Meanwhile, FIG. 3B shows a detailed configuration of a 5G CPE that transmits a 5G radio signal between a 5G base station and a UE according to an embodiment. Referring to FIG. 3B , the 5G CPE 500 includes a reception antenna (RX ANT), a transmission antenna (TX ANT), a control unit 510 , and a transmission/reception unit 520 .

In this regard, the 5G CPE 500 may amplify and process the 5G radio signal received from the 5G base station 700 through the reception antenna (RX ANT) through the transceiver 520 . In addition, the 5G CPE 500 may transmit the amplified and processed 5G radio signal to the first UE 100a and the second UE 100b through a transmit antenna (TX ANT). In this case, the receiving antenna RX ANT and the transmitting antenna TX ANT may share an antenna element.

Meanwhile, the reception antenna RX ANT includes a plurality of antennas ANT1 to ANT4 , and may simultaneously receive a plurality of signals from the 5G base station 700 in the same band. Accordingly, the 5G CPE 500 may perform DL-MIMO of up to 4 RX.

In addition, the reception antenna (RX ANT) receives a plurality of signals from a plurality of terminals including the first UE 100a and the second UE 100b and simultaneously transmits a plurality of signals to the 5G base station 700 in the same band. can Accordingly, the 5G CPE 500 may perform UL-MIMO of up to 4 TX.

In addition, the transmit antenna (TX ANT) receives a plurality of signals from a plurality of terminals including the first UE 100a and the second UE 100b and simultaneously transmits a plurality of signals to the 5G base station 700 in the same band. can

On the other hand, the 5G CPE 500 does not have to have both a receive antenna (RX ANT) and a transmit antenna (TX ANT). In this regard, the 5G CPE 500 may include only a reception antenna (RX ANT), and a separate independent communication relay device may include a transmission antenna (TX ANT).

As described above, with respect to an electronic device having a plurality of antennas, that is, a communication relay device, an electronic device having a cone antenna according to the present invention will be described below.

In this regard, FIG. 4A is a perspective view of a three-dimensional structure of a cone antenna connected to a feeding unit and a feeding unit in relation to the present invention.

4B shows the structure of an electronic device including a plurality of cone antennas, a transceiver circuit, and a processor according to the present invention.

Referring to FIGS. 4A and 4B , an electronic device having an antenna according to the present invention includes a cone antenna 1100 . Here, the cone antenna 1100 is configurable to include a metal patch 1101 , a cone radiator 1100R shorting pin 1102 , and a power supply unit 1105 .

Meanwhile, in FIG. 4A , the ground layer GND corresponding to the power feeding unit 1105 may be removed from the rear surface of the second substrate S2 on which the power feeding unit 1105 feeding the cone radiator 1100R is disposed. Accordingly, as the ground layer GND corresponding to the power supply unit 1105 is removed, a ground characteristic for the signal line in the second substrate S2 or another substrate coupled to the second substrate S2 may be reduced.

4A and 4B, the cone antenna 1100 includes a first substrate S1 corresponding to an upper substrate, a second substrate S2 corresponding to a lower substrate, and a cone radiator ( 1100R) is configurable. In addition, the cone antenna 1100 may be configured to further include a metal patch 1101 , a shorting pin 1102 , and a power supply unit 1105 .

Also, the cone antenna 1100 is configurable to further include an outer rim 1103 and a fastener 1104 to be fixed to the first substrate S1 through the outer rim 1103 . In addition, the cone antenna 1100 is configurable to further include a fastener 1107 for fastening the non-metal supporter 1106 and the feeding unit 1105 . Here, the fasteners 1104 and 1107 may be implemented as fasteners such as screws having a predetermined diameter.

In this regard, the second substrate S2 may be spaced apart from the first substrate S1 by a predetermined interval, and may include a ground layer GND. Meanwhile, the cone radiator 1100R may be disposed between the first substrate S1 and the second substrate S2 . Specifically, the cone radiator 1100R may vertically connect the first substrate S1 and the second substrate S2 to the first substrate S1 and the second substrate S2 . In addition, the cone radiator 1100R has an upper portion connected to the first substrate S1 , and a lower portion connected to the second substrate S2 , and may be configured to have an upper aperture on the upper portion.

Meanwhile, the metal patch 1101 may be formed on the first substrate S1 and spaced apart from the upper opening. In this regard, the metal patch 1101 may be formed as a circular patch having an outer side shape of a circular shape. However, the shape of the metal patch 1101 is not limited thereto, and may be formed as a rectangular patch having a rectangular outer shape.

Meanwhile, the inner side shape of the metal patch 1101 may be formed in a circular shape to correspond to the shape of the outline of the upper opening regardless of the outer shape of the metal patch 1101 . Through this, a signal radiated from the cone radiator 1100R may be coupled through the inside of the metal patch 1101 .

Meanwhile, the metal patch 1101 may be disposed on only one side to surround a partial area of the upper opening of the cone antenna 1100 . Accordingly, the overall size of the cone antenna 1100 including the metal patch 1101 may be minimized. However, the shape and arrangement of the metal patch 1101 is not limited to a circular patch disposed only on one side of the upper opening. Accordingly, the metal patch 1101 may be implemented as a square patch disposed on one side, a circular patch disposed on both sides, or a square patch disposed on both sides. The shape and arrangement of the metal patch 1101 will be described in detail below.

Meanwhile, the power feeding unit 1105 is formed on the second substrate S2 and configured to transmit a signal through a lower aperture. To this end, the power feeding unit 1105 may have an end portion having a ring shape to correspond to the shape of the lower opening.

Meanwhile, a shorting pin 1102 is formed to electrically connect the metal patch 1101 and the ground layer GND of the second substrate S2 . Meanwhile, the shorting pin 1102 may be implemented in a structure in which a fastener such as a screw having a predetermined diameter is inserted into a structure such as a dielectric.

In this regard, in order to arrange a plurality of cone antennas in an electronic device, the cone antennas need to be implemented with a small size. For this purpose, the cone antenna structure according to the present invention may be referred to as “Cone with shorting pin” or “Cone with shorting supporter”.

In this regard, the number of shorting pins or shorting supporters may be one or two. Specifically, the number of shorting pins or shorting supports is not limited thereto and can be changed according to applications. However, in the "Cone with shorting pin" or "Cone with shorting supporter" according to the present invention, one or two shorting pins or shorting supports may be implemented to reduce the size of the antenna.

Specifically, a shorting pin 1102 may be formed as a single shorting pin between the metal patch 1101 and the second substrate S2 . By such a single shorting pin 1102, it is possible to prevent a null (null) of the radiation pattern of the cone antenna from being generated.

In this regard, a typical cone antenna has a problem in that a null of a radiation pattern is generated in a boresight in an elevation angle direction, so that reception performance is deteriorated. In order to solve this problem, in the present invention, through the structure in which the cone antenna 1110 is connected to one shorting pin 1102 , the null of the radiation pattern in the boresight in the elevation direction can be removed. Accordingly, the present invention has an advantage that reception performance can be improved in almost all directions.

In this regard, the cone antenna with one shorting pin forms the current path of the feeding part 1105 - the cone radiator 1100R - the metal patch 1101 - the shorting pin 1102 - the ground layer GND. In this way, through the asymmetric current path of the feeding part 1105 - the cone radiator 1100R - the metal patch 1101 - the shorting pin 1102 - the ground layer (GND), the radiation pattern at the bore site in the elevation direction is null ( null) can be prevented.

Meanwhile, as described above, the shorting pin 1102 may be formed of a screw having a predetermined diameter configured to vertically connect between the metal patch 1101 and the second substrate S2 . In this regard, the height of the shorting pin 1102 may be set to 2 mm and the diameter to 1.5 mm. However, the height and diameter of the shorting pin 1102 are not limited thereto and may be changed according to the application.

On the other hand, it may be difficult to ensure mechanical stability only with the shorting pin 1102 having such a specific diameter. Accordingly, in order to secure mechanical stability by the shorting pin 1102 , a second dielectric 1102a may be further included. That is, the second dielectric 1102a is formed to surround the screw corresponding to the shorting pin 1102 and has a cylindrical shape with a predetermined diameter.

On the other hand, the cone antenna according to the present invention, in order to mechanically fix the cone radiator 1100R, the first substrate S1 and the second substrate S2, at least one non-metal supporter (non-metal supporter, 1106). ) may be further included. To this end, the non-metallic support 1106 is configured to vertically connect the first substrate S1 and the second substrate S2 to support the first substrate S1 and the second substrate S2 . On the other hand, since the non-metallic support 1106 is not metal and is not electrically connected to the metal patch 1101 , it does not affect the electrical characteristics of the cone antenna 1100 . Accordingly, the non-metal support 1106 connects and supports the first and second substrates S1 and S2 in a vertical manner so as to support the upper left, upper right, and lower left sides of the first and second substrates S1 and S2. and may be disposed in the lower right. However, the present invention is not limited thereto, and various structures capable of supporting the first substrate S1 and the second substrate S2 may be changed according to application.

Meanwhile, the plurality of outer rims 1103 form an upper opening of the cone radiator 1100R and are configured to connect the cone antenna to the first substrate S1 . Accordingly, the outer rim 1103 may be integrally formed with the cone radiator 1100R, and may be connected to the first substrate S1 through the fastener 1104 . In addition, the plurality of fasteners 1104 is configured to connect the outer rim 1103 and the first substrate S1.

Here, the outer rim 1103 and the fastener 1104 may be implemented as two outer rims on opposing points of the cone radiator 1100R. However, the number of the outer rim 1103 and the fastener 1104 is not limited thereto, and may be implemented with three or more outer rims depending on the application.

On the other hand, the fastener 1104 may be configured to be connected to the second substrate S2 through the inside of the end (ie, a ring shape) of the power feeding unit 1105 . Accordingly, the second substrate S2 on which the power feeding part 1105 is formed and the cone radiator 1100R may be fixed through the fastener 1107 . Accordingly, the fastener 1107 serves to fix the cone radiator 1100R to the second substrate S2 as well as a role of a power feeder that transmits a signal to the cone radiator 1100R.

Meanwhile, the antenna layer may be the first substrate S1 corresponding to the upper substrate. Meanwhile, the transceiver circuit layer may be the second substrate S2 and/or the third substrate corresponding to the lower substrate. In this regard, the third substrate may be disposed under the second substrate S2 . Here, the transceiver circuit 1250 may be connected to the cone radiator 1100R through the feeding unit 1105 , and may control to radiate a signal through the cone antenna 1100 . To this end, the transceiver circuit 1250 may control the operation of the transmitter or receiver circuit connected to the cone antenna 1100 . Specifically, the transceiver circuit 1250 may control the output power of a power amplifier (PA) of the transmitter. Also, the transceiver circuit 1250 may adjust the gain of a low noise amplifier (LNA) of the receiver.

Meanwhile, when the transceiver circuit 1250 is disposed on the second substrate S2 , the length of the connection with the power supply unit 1105 may be reduced. On the other hand, when the transceiver circuit 1250 is disposed on the third substrate, it is advantageous in terms of mounting space, and when a plurality of cone antennas 1100 are disposed, interference with the cone antenna 1100 can be reduced.

The transceiver circuit 1250 may be connected to the cone radiator 1100R through the feeding unit 1105 , and may control to radiate a signal through the cone antenna 1100 . In this regard, the transceiver circuit 1250 may include a power amplifier 210 and a low-noise amplifier 310 at the front end as shown in FIG. 2 . Accordingly, the transceiver circuit 1250 may control the power amplifier 210 to radiate the signal amplified through the power amplifier 210 through the cone antenna 1100 . Also, the transceiver circuit 1250 may control the low noise amplifier 310 to amplify the signal received from the cone antenna 1100 through the low noise amplifier 310 . In addition, the transceiver circuit 1250 may control elements inside the transceiver circuit 1250 to transmit and/or receive a signal through the cone antenna 1100 .

In this regard, when the electronic device includes a plurality of cone antennas, the transceiver circuit 1250 may control a signal to be transmitted and/or received through at least one of the plurality of cone antennas. A case in which the transceiver circuit 1250 transmits or receives a signal through only one cone antenna may be referred to as 1 Tx or 1 Rx, respectively. On the other hand, a case in which the transceiver circuit 1250 transmits or receives a signal through two or more cone antennas may be referred to as n Tx or n Rx depending on the number of antennas.

For example, a case in which the transceiver circuit 1250 transmits or receives a signal through two cone antennas may be referred to as 2 Tx or 2 Rx. However, when the transceiver circuit 1250 transmits or receives the first and second signals having the same data through two cone antennas, it may be referred to as 1 Tx or 2 Rx. A case in which the transceiver circuit 1250 transmits or receives the first and second signals having the same data through the two cone antennas as described above may be referred to as a diversity mode.

The electronic device having the cone antenna 1100 may be implemented as an antenna system including a plurality of cone antennas. In this regard, FIG. 4B shows the structure of an electronic device including a plurality of cone antennas, a transceiver circuit, and a processor according to the present invention.

Referring to FIG. 4B , the electronic device may include four cone antennas, that is, a first cone antenna 1100-1 to a fourth cone antenna 1100-4. Here, the number of cone antennas can be changed to various numbers according to applications. Here, the first cone antenna 1100-1 to the fourth cone antenna 1100-4 may be implemented in the same shape for the same antenna performance. In addition, the first cone antenna 1100-1 to the fourth cone antenna 1100-4 may be implemented in different shapes for optimal antenna performance and an optimal arrangement structure.

Here, the electronic device may be implemented in a communication relay apparatus, a small cell base station, or a base station in addition to a user terminal (UE). Here, the communication relay device may be a Customer Premises Equipment (CPE) capable of providing 5G communication services indoors.

Meanwhile, the antenna system disposed in the electronic device includes a plurality of cone antennas, for example, a first cone antenna 1100-1 to a fourth cone antenna 1100-4. Specifically, it may be implemented with a plurality of cone antennas disposed on the upper left, upper right, lower left, and lower right of the antenna system, that is, the first to fourth cone antennas 1100-1 to 1100-4. In this regard, the plurality of cone antennas 1100-1 to 1100-4 may include metal patches 1101-1 and 1101-2, a cone radiator 1100R, and a power supply unit 1105.

In addition, the antenna system may further include a transceiver circuit 1250 . Also, the antenna system may further include a processor 1400 . Here, the processor 1400 may be a baseband processor configured to control the transceiver circuit 1250 .

In this regard, the transceiver circuit 1250 is respectively connected to the cone radiator 1100R through the power supply unit 1105 . Also, the transceiver circuit 1250 may control the first signal of the first frequency band to be radiated through the cone antenna 1110 . Also, the transceiver circuit 1250 may control to radiate a second signal of a second frequency band lower than the first frequency band through the cone antenna 1110 .

In this regard, the processor 1400 may control the transceiver 1250 to perform multiple input/output (MIMO) through two or more of the plurality of cone antennas 1100-1 to 1100-4.

When the resource of the first frequency band is allocated to the electronic device, the processor 1400 transmits/receives unit 1250 to perform multiple input/output (MIMO) through two or more of the plurality of cone antennas 1100-1 to 1100-4. ) to control To this end, when the resource of the first frequency band is allocated to the electronic device, the processor 1400 may control the transceiver circuit 1250 to operate in the first frequency band. In this regard, the processor 1400 may inactivate some components of the transceiver circuit 1250 operating in the second frequency band.

On the other hand, when the resource of the second frequency band is allocated to the electronic device, the processor 1400 transmits/receives to perform multiple input/output (MIMO) through two or more of the plurality of cone antennas 1100-1 to 1100-4. control unit 1250 . To this end, when the resource of the second frequency band is allocated to the electronic device, the processor 1400 may control the transceiver circuit 1250 to operate in the second frequency band. In this regard, the processor 1400 may inactivate some components of the transceiver circuit 1250 operating in the first frequency band.

Meanwhile, when both the resource of the first frequency band and the resource of the second frequency band are allocated to the electronic device, the processor 1400 may use only one cone antenna. To this end, the processor 1400 may control the transceiver circuit 1250 to perform carrier aggregation (CA) on the first signal and the second signal received through one cone antenna. Accordingly, the processor 1400 may simultaneously acquire both the first and second information included in the first and second signals, respectively.

Meanwhile, the cone antenna according to the present invention may be configured to operate in both the middle band (MB) and the high band (HB). In this regard, the cone antenna may be configured to operate in all of the low band (LB), middle band (MB) and high band (HB). However, when the cone antenna operates even in the low band LB, the volume of the cone radiator may increase and impedance matching characteristics may deteriorate in the high band HB.

In this regard, FIG. 5A is a side view of a cone antenna and a conceptual diagram illustrating a multi-resonance principle according to an exemplary embodiment. Meanwhile, FIG. 5B shows reflection coefficient characteristics of a cone antenna according to an exemplary embodiment.

In this regard, the low band LB may be considered to include 650 MHz to 900 MHz or 600 MHz to 960 MHz. However, the low band LB is not limited thereto and may be changed according to applications. Meanwhile, the middle band (MB) may be regarded as a frequency band starting from 1400 MHz, but is not limited thereto and may be changed according to applications. In addition, the high band (HB) is a band higher than the middle band (MB) and may be considered as a frequency band starting from 2500 MHz or 3500 MHz, but is not limited thereto and may be changed according to an application.

4A and 5A , the first path including the cone radiator 1100R, the metal patch 1101 and the shorting pin 1102 resonates at a first frequency f1 corresponding to the low band LB. This can happen. Meanwhile, resonance may occur at the second frequency f2 corresponding to the middle band MB by the second path including the cone radiator 1100R and the fastener 1104 fastened through the outer rim. Also, resonance may occur at the third frequency f3 corresponding to the high band HB by the third path by the cone radiator 1100R.

In this regard, referring to FIGS. 4A, 5A and 5B , it can be seen that the cone antenna 1000 operates as a multi-band antenna resonating in both the middle band MB and the high band HB. Specifically, it can be seen that the cone antenna 1000 operates in a wide band from about 1.2 GHz to about 4.3 GHz.

On the other hand, it is necessary to change the design of the cone antenna 1000 according to the present invention to operate in the 5G Sub 6 band, about 5 GHz to 6 GHz. In this regard, it will be described in detail with reference to FIGS. 7A to 9C.

On the other hand, when examining the radiation pattern requirements by the antenna provided in the electronic device according to the present invention, that is, a communication relay device as follows. In this regard, FIG. 6A shows a radiation pattern pattern by an antenna of a communication relay device. Specifically, FIG. 6a (a) shows a radiation pattern by a dipole or monopole type antenna provided in a communication relay device in relation to the present invention. On the other hand, FIG. 6a(b) shows a radiation pattern by an antenna provided in a communication relay device according to an example. In this regard, FIG. 6B shows a current distribution diagram for different antennas of the communication relay device of FIG. 6A, that is, a data device, and a principle of forming a radiation pattern according thereto.

Referring to FIG. 6A, unlike the omnidirectional radiation pattern of a general external antenna, it is necessary to concentrate the antenna radiation in the upper hemisphere region, which is advantageous for the customer use scene. Therefore, by using the cone antenna of the structure as shown in Figs. 4a and 4b, it has the same or better performance as the external communication repeater based on the Hemisphere and has a design merit differentiated by the small height characteristic.

Specifically, in the structure shown in FIG. 6a (a), the antenna size supporting LTE + Sub 6GHz requires a height of at least 140 mm or more due to the antenna size. However, in the structure shown in FIG. 6A( b ), the data device including the cone antenna has a low profile structure to have a size of about 40 mm and a height of about 16 mm.

Meanwhile, referring to FIGS. 6A (a) and 6B (a), a monopole or dipole antenna generates a surface current in a surrounding area by a current on the surface of the antenna. In this case, the monopole or dipole antenna is formed substantially perpendicular to the data device surface. Thus, a data device with a monopole or dipole antenna would have a height of about 140 mm. In addition, the radiation pattern is mainly formed in the horizontal direction in the data device according to the surface current formed around the direction perpendicular to the surface of the data device. Accordingly, communication performance may be deteriorated at a position greater than or equal to the height at which the data device is disposed.

On the other hand, referring to FIGS. 6A(B) and 6B(B) , a current is generated along the surface of the cone antenna and the circuit board disposed parallel to the data device. Therefore, a surface current is generated by the electric field generated along the surface of the circuit board and the cone antenna. Further, the radiation pattern is mainly formed in a direction substantially perpendicular to the surface current. Accordingly, communication performance may be improved at a position at an angle greater than or equal to the height at which the data device is disposed.

A method of feeding a signal to a cone radiator through a feeding unit in the electronic device having the aforementioned cone antenna and performing wideband matching around the feeding unit through a wideband impedance matching unit will be described. In this regard, FIG. 7A shows the detailed configuration of the cone radiator and the power feeding unit connected to the feeding unit. Meanwhile, FIG. 7B shows a Smith chart showing impedance characteristics of the cone antenna of FIG. 7A and an equivalent circuit.

Meanwhile, FIG. 8A shows a detailed configuration of a cone antenna combined with a power feeding unit and a matching stub according to an exemplary embodiment. Meanwhile, FIG. 8B shows a Smith chart showing impedance characteristics of the antenna of FIG. 8A and an equivalent circuit.

Meanwhile, the structural and technical characteristics of the broadband cone antenna using the T-Type stub matching structure according to the present invention are as follows.

- In this regard, 5G Data Device is mainly installed and used on walls, desks, and top surfaces of tables. Therefore, it is advantageous for the antenna radiation direction to radiate in the hemisphere direction as shown in FIG. 6a(b) rather than in the omnidirectional direction like a mobile terminal.

- The existing data device uses an external antenna having an Omni-Directional Radiation Pattern as shown in FIG. 6a(a). However, the built-in antenna of the 5G Data Device can apply a Cone Type Antenna structure having a hemisphere radiation pattern characteristic.

- 5G Data Device Support Band: Requires broadband frequency coverage from 1175MHz (GPS L5) to 6GHz (Sub-6 N79, B46).

- Limitations of the prior art: The operating band of the cone antenna that can be used as a vehicle antenna has an operating band of 1175 MHz to 4.5 GHz. Therefore, it is insufficient to cover the entire Sub6 Band (N79 4.4 to 5 Hz) and B46 Band (5.15 to 5.925 GHz).

- The method of improving the resonance characteristics by changing the cone shape and size has limitations in common use of parts and requires modification of the mold.

- On the other hand, when matching with Lumped Element at the feeding stage, it is difficult to apply a matching structure that can satisfy the entire broadband due to the high Q characteristic of the element itself.

- Necessity of the concept of the present invention: In the basic operating band of the wideband Cone antenna, that is, 1175 MHz to 4.3 GHz, there is a need for a method to selectively improve the resonance characteristics among the 4 GHz to 6 GHz bands.

Meanwhile, the effects of the T-Type Stub Matching structure according to the present invention are as follows. Capacitive Matching effect can be generated by adding T-Type Ground Stub on the opposite side of PCB of Feeding Line of cone emitter. On the other hand, the T-Type length is adjusted to about 1/10 wavelength of the desired tuning frequency, so that frequency tuning is possible.

In this regard, the second substrate S2 serving as the lower substrate may be spaced apart from the first substrate S1 by a predetermined distance and may be configured to include a ground layer. Meanwhile, the cone radiator 1100R may be configured to be provided between the first substrate S1 and the second substrate S2 . Also, the cone radiator 1100R may be connected to the first substrate S1 and the lower portion connected to the second substrate S2, and may be configured to have an upper opening and a lower opening.

Meanwhile, the metal patch 1101 may be formed on the first substrate S1 and spaced apart from the upper opening. In addition, the shorting pin 1102 may be formed to electrically connect the metal patch 1101 and the ground layer of the second substrate S2 .

Meanwhile, the power feeding unit 1105 may be formed on the second substrate S2 and configured to transmit a signal through the lower opening. The transceiver circuit 1250 may be connected to the cone radiator 1100R through the feeding unit 1105 , and may be configured to control to radiate a signal through the cone antenna 1100 . In this regard, the power feeding unit 1105 may be formed on the front surface of the second substrate S2 , and matching stubs TS1 and TS2 may be disposed on the rear surface of the second substrate S2 . In this case, the ground layer may be removed around the area where the matching stubs TS1 and TS2 are disposed.

Meanwhile, the feeder 1105 may be configured to include a transmission line 1105 - 1 and a signal feeder 1105 - 2 . In this regard, the transmission line 1105 - 1 may be connected to the transceiver circuit and configured to receive a signal from the transceiver circuit. Also, the signal feeding unit 1105 - 2 may have an end portion having a ring shape to correspond to the shape of the lower opening.

4A, 5B, 7A and 7B, the cone antenna 1100 including the cone radiator 1100R, the metal patch 1101, the shorting pin 1102, and the fastening fastened to the outer rim It can be seen that multiple resonance occurs by the sphere 1104 .

Meanwhile, the matching stub may be configured to include a first stub TS1 and a second stub TS2. In this regard, the first stub TS1 may be disposed on the rear surface of the second substrate S2 in parallel to the transmission line 1105 - 1 . For example, the width of the first stub TS1 may be the same as the width of the transmission line 1105 - 1 or may be wider by a certain ratio. Accordingly, a signal transmitted through the transmission line 1105 - 1 may be guided and transmitted along the transmission line 1105 - 1 without being radiated to the outside.

For example, the width of the first stub TS1 may be the same as the width of the transmission line 1105 - 1 . Also, the first stub TS1 may be aligned at a position corresponding to the front surface of the second substrate S2 on which the transmission line 1105 - 1 is disposed.

Meanwhile, the second stub TS2 may be connected to an end of the first stub TS1 and may be configured to extend in a direction perpendicular to the first stub TS1 . In this regard, a signal transmitted through the transmission line 1105 - 1 may be reflected due to impedance mismatch at a point where it is transmitted to the ring-shaped signal feeding unit 1105 - 2 . Accordingly, the signal reflected by the impedance mismatch is matched through the second stub TS2 and transmitted to the signal feeding unit 1105 - 2 again.

Meanwhile, referring to FIGS. 4A, 8A and 8B , the cone antenna 1100 including a cone radiator 1100 includes a cone radiator 1100R, a metal patch 1101, a shorting pin 1102, and a fastener fastened to the outer rim. It can be seen that multi-resonance occurs by the first and second stubs TS1 and TS2 together with 1104 . In this case, it can be seen that the first and second stubs TS1 and TS2 are capacitively coupled to the power supply unit 1105 and thus have a wider resonance than that of FIG. 7B .

In this regard, FIGS. 9A to 9C show Smith charts and VSWRs showing impedance characteristics of antennas according to different types of matching stubs and without a matching stub. 9A shows the Smith chart and VSWR in the absence of a matching stub. On the other hand, FIG. 9B shows the Smith chart and VSWR when the first and second stubs TS1 and TS2 are provided.

Referring to FIG. 9A , it can be seen that the cone antenna has a VSWR of 3 or less at about 1.1 GHz to 4.3 GHz, and thus the operating band is about 1.1 GHz to 4.3 GHz. On the other hand, referring to FIG. 9B , it can be seen that the cone antenna has a VSWR of 3 or less at about 1.1 GHz to 5.3 GHz, and thus the operating band is about 1.1 GHz to 5.3 GHz.

As described above, FIGS. 9A to 9C show Smith charts and VSWRs showing impedance characteristics of antennas according to different types of matching stubs and without a matching stub.

4A, 4B, and 8C , the matching stub may further include a third stub TS3. In this regard, the third stub TS3 may be connected to a point of the first stub TS1 and may be configured to extend in a direction perpendicular to the first stub TS1 . Meanwhile, the third stub TS3 may be disposed parallel to the second stub TS2 .

In this regard, a signal transmitted through the transmission line 1105 - 1 may be reflected due to impedance mismatch at a point where it is transmitted to the ring-shaped signal feeding unit 1105 - 2 . Accordingly, the signal reflected by the impedance mismatch is matched through the second stub TS2 and the third stub TS3 to be transmitted to the signal feeding unit 1105 - 2 again.

In this regard, the third stub TS3 may be disposed on the rear surface of the second circuit board S2 with a predetermined length to remove unwanted radiation at discontinuous points where the ground layer is removed. In particular, at the boundary point of the circular dielectric region DR1 , the third stub TS3 may be formed to have a predetermined length equal to the width of the rectangular dielectric region.

In this regard, FIG. 9C shows a Smith chart and VSWR when the first to second stubs TS1 to TS3 are provided. Referring to FIG. 9C , it can be seen that the cone antenna has a VSWR of 3 or less in about 1.1 GHz to 6.0 GHz, and thus the operating band is about 1.1 GHz to 6.0 GHz.

In addition, the width of the second stub TS2 and the width of the third stub TS3 may be formed to have the same width as the width of the transmission line 1105 - 1 . In this case, the length of the second stub TS2 may be longer than that of the third stub TS3.

Meanwhile, the length of the second stub TS2 may be longer than the diameter of the lower opening of the cone radiator 1100R. Accordingly, the signal fed from the signal feeding unit 1105 - 2 and reflected from the lower opening of the cone radiator 1100R can be effectively transmitted back to the lower opening of the cone radiator 1100R.

Meanwhile, a dielectric region DR1 from which a ground is removed may be formed on the rear surface of the second substrate S2 centered on the region in which the power feeding unit 1105 is disposed. Accordingly, impedance matching characteristics of the signal feeding unit 1105 - 2 corresponding to the shape of the lower opening of the cone radiator 1100R may be improved. Meanwhile, the signal loss issue due to the formation of the grounded dielectric region DR1 on the rear surface of the second substrate S2 can be solved by the wideband matching stubs TS1, TS2, and TS3 proposed in the present invention.

In this regard, the first dielectric region DR1 may be formed to have a larger diameter than the diameter of the lower opening of the cone radiator 1100R. Also, the second dielectric region DR2 may extend from the first dielectric region DR1 and may be formed as a rectangular region having a predetermined width and length.

Meanwhile, referring to FIG. 8A ( b ), the sum of the length of the first matching stub TS1 formed from the end of the second dielectric region DR2 and the length of the second matching stub TS2 is the first length. can Here, the first length may be set to 6 mm, but is not limited thereto and may be set differently depending on the resonance frequency and the dielectric constant and thickness of the substrate.

Meanwhile, referring to FIG. 8C , the length from the end of the second matching stub TS2 to the end of the third matching stub TS3 may be the second length. Here, the second length may be shorter than the first length. In this regard, the second length may be set to 4 mm, and the first length may be set to 6 mm. However, the first length and the second length are not limited thereto and may be set differently depending on the resonance frequency and the dielectric constant and thickness of the substrate.

As described above, the third stub TS3 may be disposed on the rear surface of the second circuit board S2 with a predetermined length to remove unwanted radiation at discontinuous points where the ground layer is removed. In particular, at the boundary point of the circular dielectric region DR1 , the third stub TS3 may be formed to have a predetermined length equal to the width of the rectangular dielectric region.

On the other hand, a signal transmitted through the transmission line 1105 - 1 may be reflected due to impedance mismatch at a point where it is transmitted to the ring-shaped signal feeding unit 1105 - 2 . Accordingly, the signal reflected by the impedance mismatch is matched through the second stub TS2 and transmitted to the signal feeding unit 1105 - 2 again. Accordingly, the length of the second stub TS2 may be longer than the length of the third stub TS3.

Meanwhile, referring to FIG. 4A , the shorting pin 1102 may be formed as a single shorting pin vertically connected between the metal patch 1101 and the second substrate S2 . By the single shorting pin, it is possible to prevent a null of the radiation pattern of the cone antenna from being generated. Meanwhile, in addition to the shorting pin 1102 , a plurality of non-metallic supports 1106 may be disposed to connect the first substrate S1 and the second substrate S2 for structural stability of the cone antenna assembly.

Meanwhile, the shorting pin 1102 may be formed of a screw having a predetermined diameter configured to vertically connect between the metal patch 1101 and the second substrate S2 . In addition, it may further include a second dielectric formed to surround the screw corresponding to the shorting pin 1102 and configured in a cylindrical shape with a predetermined diameter.

Meanwhile, the cone antenna 1100 is configurable to further include a plurality of outer ribs 1103 and fasteners 1104 . The outer rim 1103 may be configured to form an upper opening of the cone antenna 1100 and connect the cone antenna 1100 to the first substrate S1 . In addition, the outer rim 1103 may be provided in plurality, and may be expanded to 2, 3, 4, 5, 6, etc. to generate multiple resonance. In addition, the fastener 1104 may be configured to connect the outer rim 1103 and the first substrate S1 .

Meanwhile, the metal patch 1100 may be disposed on only one side to surround a partial area of the upper opening of the cone antenna 1100 . Accordingly, the size of the cone antenna 1100 including the metal patch 1100 may be minimized. In addition, it is possible to prevent the formation of nulls in the radiation pattern of the cone antenna 1100 in the bore site direction by forming the current flow in an asymmetrical shape.

Accordingly, the signal reflected by the impedance mismatch is matched through the second stub TS2 and the third stub TS3 to be transmitted to the signal feeding unit 1105 - 2 again.

In this regard, the third stub TS3 may be disposed on the rear surface of the second circuit board S2 with a predetermined length to remove unwanted radiation at discontinuous points where the ground layer is removed. In particular, at the boundary point of the circular dielectric region DR1 , the third stub TS3 may be formed to have a predetermined length equal to the width of the rectangular dielectric region.

In addition, the width of the second stub TS2 and the width of the third stub TS3 may be formed to have the same width as the width of the transmission line 1105 - 1 . In this case, the length of the second stub TS2 may be longer than that of the third stub TS3.

Meanwhile, the length of the second stub TS2 may be longer than the diameter of the lower opening of the cone radiator 1100R. Accordingly, the signal fed from the signal feeding unit 1105 - 2 and reflected from the lower opening of the cone radiator 1100R can be effectively transmitted back to the lower opening of the cone radiator 1100R.

Meanwhile, a dielectric region DR1 from which a ground is removed may be formed on the rear surface of the second substrate S2 centered on the region in which the power feeding unit 1105 is disposed. Accordingly, impedance matching characteristics of the signal feeding unit 1105 - 2 corresponding to the shape of the lower opening of the cone radiator 1100R may be improved. Meanwhile, the signal loss issue due to the formation of the grounded dielectric region DR1 on the rear surface of the second substrate S2 can be solved by the wideband matching stubs TS1, TS2, and TS3 proposed in the present invention.

Meanwhile, the dielectric region from which the ground is removed from the second substrate S2 centered on the region in which the power feeding unit 1105 is disposed may be configured to include the first dielectric region DR1 and the second dielectric region DR2 . In this regard, the first dielectric region DR1 may be formed to have a larger diameter than the diameter of the lower opening of the cone radiator 1100R. Also, the second dielectric region DR2 may extend from the first dielectric region DR1 and may be formed as a rectangular region having a predetermined width and length.

Meanwhile, a DL-MIMO stream of up to 4 RX may be received from the 5G base station 700 of FIG. 5B through the plurality of cone antennas 1100-1 to 1100-4 according to the present invention. Meanwhile, the plurality of cone antennas 1100-1 to 1100-4 having the first and second stubs TS1 and TS2 according to the present invention may be configured to operate at about 1.1 GHz to 5.3 GHz. In addition, the plurality of cone antennas 1100-1 to 1100-4 having the first to second stubs TS1 to TS3 according to the present invention may be configured to operate at about 1.1 GHz to 5.3 GHz.

In the above, an electronic device having an antenna according to the present invention, that is, a 5G communication relay device has been described. An electronic device having such an antenna, that is, a wireless communication system including a 5G communication relay device and a base station, will be described below. In this regard, FIG. 12 illustrates a block diagram of a wireless communication system to which the methods proposed in the present specification can be applied.

Referring to FIG. 12 , the wireless communication system includes a first communication device 910 and/or a second communication device 920 . 'A and/or B' may be interpreted as having the same meaning as 'including at least one of A or B'. The first communication device may represent the base station and the second communication device may represent the electronic device (or the first communication device may represent the electronic device and the second communication device may represent the base station).

Base station (BS) is a fixed station (fixed station), Node B, evolved-NodeB (eNB), gNB (Next Generation NodeB), BTS (base transceiver system), access point (AP: Access Point), gNB (general NB), 5G system, network, AI system, RSU (road side unit), may be replaced by terms such as robot. In addition, the terminal (Terminal) may be fixed or have mobility, UE (User Equipment), MS (Mobile Station), UT (user terminal), MSS (Mobile Subscriber Station), SS (Subscriber Station), AMS (Advanced Mobile) Station), WT (Wireless terminal), MTC (Machine-Type Communication) device, M2M (Machine-to-Machine) device, D2D (Device-to-Device) device, vehicle, robot, AI module may be replaced by terms such as

The first communication device and the second communication device include a processor 911,921, a memory 914,924, one or more Tx/Rx radio frequency modules 915,925, Tx processors 912,922, Rx processors 913,923 , including antennas 916 and 926 . The processor implements the functions, processes and/or methods salpinned above. More specifically, in DL (communication from a first communication device to a second communication device), a higher layer packet from the core network is provided to the processor 911 . The processor implements the functions of the L2 layer. In DL, the processor provides multiplexing between logical channels and transport channels, allocation of radio resources to the second communication device 920, and is responsible for signaling to the second communication device. A transmit (TX) processor 912 implements various signal processing functions for the L1 layer (ie, the physical layer). The signal processing function facilitates forward error correction (FEC) in the second communication device, and includes coding and interleaving. The coded and modulated symbols are divided into parallel streams, each stream mapped to OFDM subcarriers, multiplexed with a reference signal (RS) in the time and/or frequency domain, and using Inverse Fast Fourier Transform (IFFT) are combined together to create a physical channel carrying a stream of time domain OFDMA symbols. The OFDM stream is spatially precoded to generate multiple spatial streams. Each spatial stream may be provided to a different antenna 916 via a separate Tx/Rx module (or transceiver) 915 . Each Tx/Rx module may modulate an RF carrier with a respective spatial stream for transmission. In the second communication device, each Tx/Rx module (or transceiver) 925 receives a signal via each antenna 926 of each Tx/Rx module. Each Tx/Rx module recovers information modulated with an RF carrier and provides it to a receive (RX) processor 923 . The RX processor implements the various signal processing functions of layer 1. The RX processor may perform spatial processing on the information to recover any spatial streams destined for the second communication device. If multiple spatial streams are destined for the second communication device, they may be combined into a single OFDMA symbol stream by multiple RX processors. The RX processor uses a Fast Fourier Transform (FFT) to transform the OFDMA symbol stream from the time domain to the frequency domain. The frequency domain signal includes a separate OFDMA symbol stream for each subcarrier of the OFDM signal. The symbols and reference signal on each subcarrier are recovered and demodulated by determining the most probable signal placement points transmitted by the first communication device. These soft decisions may be based on channel estimate values. The soft decisions are decoded and deinterleaved to recover the data and control signal originally transmitted by the first communication device on the physical channel. Corresponding data and control signals are provided to a processor 921 .

The UL (second communication device to first communication device) is handled in the first communication device 910 in a manner similar to that described with respect to the receiver function in the second communication device 920 . Each Tx/Rx module 925 receives a signal via a respective antenna 926 . Each Tx/Rx module provides an RF carrier and information to the RX processor 923 . The processor 921 may be associated with a memory 924 that stores program code and data. Memory may be referred to as a computer-readable medium.
