Hereinafter, a structure of a multiplex transmission/reception system according to the present invention and an electronic device having the same, in particular, an antenna 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 can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

2A is a diagram illustrating a configuration of a wireless communication unit of an electronic device capable of operating in a wireless communication system of 5G Sub 6 band or less according to the present invention. Meanwhile, FIG. 2B shows a configuration of a wireless communication unit of an electronic device capable of operating in a wireless communication system below a mmWave band according to the present invention.

2A and 2B, the electronic device includes a first power amplifier 210, a second power amplifier 220, and an RFIC 250. In addition, the electronic device may further include a modem 400 and an application processor (AP) 450. Here, the modem (Modem, 400) and the application processor (AP, 450) and physically implemented in one chip, it may be implemented in a form that is logically and functionally separated. However, the present invention is not limited thereto and may be implemented in the form of a physically separated chip according to an 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 control unit 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 and has an 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 5G band and the 4G band have a large difference in bands, 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. In this way, when the RFIC 250 is configured as a 4G/5G separate type, there is an advantage in 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 physically, it is possible to be implemented on one chip.

On the other hand, 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 an electronic device. Accordingly, the modem 400 may operate the power circuit of the transmitter and the receiver through the RFIC 250 in a low power mode.

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 the idle mode, the RFIC through the modem 400 so that at least one of the first and

second power amplifiers

110 and 120 operates in a low power mode or is turned off. 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 an 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, even though the throughput is slightly sacrificed, 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.

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 capacity 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 capacity and available radio resources are sufficient, the application processor (AP, 450) may control the modem 400 and the RFIC 250 to receive reception through both the 4G base station and the 5G base station.

Meanwhile, in the multi-transceiving system of FIG. 2, the transmitting unit and the receiving unit of each radio system may be integrated into a single transmitting/receiving unit. Accordingly, there is an advantage in that a circuit part integrating two types of system signals can be removed from the RF front-end.

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

In addition, when the communication systems are separated, it is impossible to control other communication systems as necessary, or because a system delay is increased due to this, it is impossible to efficiently allocate resources. On the other hand, the multiple transmission/reception system as shown in FIG. 2 has the advantage of enabling efficient resource allocation since it is possible to control other communication systems as needed, and thereby minimize system delay.

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 can 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 may operate in the 4G band and the other may operate in the millimeter wave band. have.

On the other hand, by integrating the transmitting and receiving unit and the receiving unit, it is possible to implement two different wireless communication systems with one antenna using a transmission/reception combined antenna. In this case, 4x4 MIMO can be implemented using 4 antennas as shown in FIG. 2. In this case, 4x4 DL MIMO may be performed through 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 can be implemented 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 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 with 1 Tx, only one of the first and

second power amplifiers

210 and 220 needs to operate in the 5G band. Meanwhile, when the 5G communication system is implemented with 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, a switch-type splitter or power divider is built into the RFIC corresponding to the RFIC 250, so that separate parts do not need to be placed outside, thereby improving component mounting performance. I can. Specifically, it is possible to select the transmission unit (TX) of two different communication systems by using a single pole double throw (SPDT) type switch inside the RFIC corresponding to the control unit 250.

In addition, an 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 separate signals in the transmission band and the reception band from each other. In this case, the signal of the transmission band transmitted through the first and

second power amplifiers

210 and 220 is applied to the antennas ANT1 and ANT4 through the first output port of the duplexer 231. On the other hand, signals in the reception band received through the antennas ANT1 to ANT4 are received by the

low noise amplifiers

310 and 340 through the second output port of the duplexer 231.

In this regard, the antennas ANT1 to ANT4 of FIG. 2A are configured to transmit and/or receive signals at frequencies below the 5G Sub 6 band. In this regard, each of the antennas ANT1 to ANT4 of FIG. 2A may be implemented as one radiating element. In this regard, each of the antennas ANT1 to ANT4 of FIG. 2A corresponds to the cone antennas 1100-1 to 1100-4 of FIGS. 4A to 5A.

Meanwhile, the antennas ANT1 to ANT4 of FIG. 2B are configured to transmit and/or receive signals at a frequency of a millimeter wave (mmWave) band. In this regard, each of the antennas ANT1 to ANT4 of FIG. 2B may be implemented as an array antenna in which a plurality of radiating elements are arranged.

Meanwhile, the antennas ANT1 to ANT4 of FIG. 2B implemented as array antennas may be connected to the power and phase controller 230. In this case, the magnitude and phase of a signal transmitted to each radiating element of the antennas ANT1 to ANT4 through the power and phase controller 230 may be controlled. Accordingly, beamforming may be independently performed for each antenna ANT1 to ANT4 in a millimeter wave (mmWave) band. In this regard, each of the antennas ANT 1 and ANT 2 of FIG. 2B corresponds to the first and second array antennas ANT1 and ANT2 of the millimeter wave array antenna module of FIG. 5A.

Meanwhile, the

power amplifiers

210 and 220 and the

low noise amplifiers

310 and 320 are configured to amplify signals in a millimeter wave (mmWave) band. In addition, the RF circuit of the transceiver circuit 250 is configured to operate in a millimeter wave (mmWave) band. Meanwhile, the baseband processor 400 of FIG. 2B may be integrally formed with the baseband processor 400 of FIG. 2A or may be formed separately.

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

The switch 233 is configured to transmit only either a transmission signal or a reception signal. In an embodiment of the present invention, the switch 233 may be configured in the form of a single pole double throw (SPDT) to separate a transmission signal and a reception signal in a time division multiplexing (TDD) scheme. 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.

Meanwhile, in another embodiment of the present invention, the switch 233 is applicable to a frequency division multiplexing (FDD) scheme. In this case, the switch 233 may be configured in the form of a Double Pole Double Throw (DPDT) so as to connect or block a transmission signal and a reception signal, respectively. On the other hand, 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 control unit (or a first processor) and a second control unit (a 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 divided into one circuit logically or functionally.

The modem 400 may perform control and signal processing 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 a 4G base station and/or a 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 at 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, specific operations and functions of an electronic device including a plurality of antennas operating in different bands according to the present invention equipped with a multiple transmission/reception system as shown in FIGS. 2A and 2B will be described below.

In the 5G communication system according to the present invention, the 5G frequency band may include a Sub6 band and/or an LTE frequency band higher than the LTE frequency band. As described above, whether a 4G communication system and a 5G communication system can be supported, a broadband antenna needs to be provided to the electronic device. In this regard, the present invention provides a broadband antenna (eg, a cone antenna) operable from a low frequency band to about 5 GHz band.

Here, the communication relay device may be a Customer Premises Equipment (CPE) capable of providing 5G communication services indoors. In addition, the cone antenna according to the present invention may be mounted on a vehicle other than electronic devices to provide 4G communication service and 5G communication service.

Meanwhile, referring to FIG. 2, a plurality of antennas (eg, cone antennas) ANT 1 to ANT 4 may be disposed on the side or rear surface of the electronic device 100.

Meanwhile, referring to FIGS. 2 and 3, at least one signal may be transmitted or received through a plurality of antennas 1110a to 1110d corresponding to the plurality of antennas ANT 1 to ANT 4. In this regard, each of the plurality of antennas 1110a to 1110d may be configured as one cone antenna. The electronic device can communicate with the base station through any one of the plurality of cone antennas 1110a to 1110d.

Hereinafter, an electronic device having a cone antenna according to the present invention will be described.

In this regard, FIGS. 4A and 4C show a communication relay apparatus including a broadband antenna (eg, a cone antenna) capable of operating from a low frequency band to about 5 GHz band according to the present invention. Specifically, FIG. 4A shows a perspective view of a three-dimensional structure of a communication relay device including a plurality of cone antennas in relation to the present invention. Meanwhile, FIG. 4B is a side view of a 3D structural diagram of a communication relay device having a plurality of cone antennas according to the present invention.

Meanwhile, FIG. 5A shows a front view of a communication relay device having a plurality of cone antennas according to the present invention. In this regard, FIG. 5B shows a perspective view of a single cone antenna element constituting a plurality of cone antennas according to the present invention.

4A to 5B, a communication relay apparatus 1000 having an antenna according to the present invention includes a conical array antenna 1100. Here, the cone array antenna 1100 is configured to include a plurality of cone antennas 1100-1 to 1100-4. Here, the number of cone array antennas 1100 is not limited to a 2x2 cone array antenna, but can be variously changed according to an application. For example, the number of cone array antennas 1100 may include a 2x1 cone array antenna, a 4x2 cone array antenna, or a 4x4 cone array antenna.

Meanwhile, since the cone array antenna 1100 operates up to the 5G Sub 6 band, separate beamforming is not required. Accordingly, the cone array antenna 1100 can be configured such that each antenna element performs multiple input/output (MIMO) without beamforming.

The cone array antenna 1100 is provided between the first substrate S1 as the upper substrate and the second substrate S2 as the lower substrate, and the upper part is connected to the first substrate S1, and the lower part is the second substrate S2. ) And is configured to be connected. Here, the first substrate S1 corresponds to the upper substrate, and the second substrate S2, which is the lower substrate, is spaced apart from the first substrate S1 by a predetermined interval and includes a ground layer GND. In addition, in the cone array antenna 1100, 　 cone radiators 1100R having an opening thereon may be arranged at predetermined intervals.

Meanwhile, the metal patches 1101-1 to 1101-4 disposed adjacent to each of the cone radiators 1100R1 to 1100R4 of the cone array antenna 1100 may also be configured with a patch array radiator 1101. have. In this regard, the patch array radiator 1101 is formed on the first substrate S1, and the metal patches 1101-1 to 1101-4 formed to be spaced apart from the upper openings of the cone radiators 1100R are arranged to be arranged. Can be.

Meanwhile, each of the metal patches 1101-1 to 1101-4 may include shorting pins 1102-1 to 1102-4 and feeders 1105-1 to 1105-4. In addition, each of the metal patches 1101-1 to 1101-4 may further include outer rims 1103-1 to 1103-4 and fasteners 1104-1 to 1104-4. .

In this regard, the shorting pins 1102-1 to 1102-4 are formed to electrically connect the metal patches 1101-1 to 1101-4 and the ground layer GND of the second substrate S2.

Meanwhile, referring to FIGS. 4A to 5B, the shape of each element of the patch array radiator 1101 may be configured differently to optimize performance. In this regard, some of the patch array radiators 1101 may have a circular patch shape, and some of the patch array radiators 1101 may have a rectangular patch shape. Specifically, the fourth metal patch 1101-4 at the lower right may have a rectangular patch shape, and the remaining first to third metal patches 1101-1 to 1101-3 may have a circular patch shape.

Meanwhile, the cone array antenna 1100 and the patch array radiator 1101 may be configured as 2x2 cone array antennas spaced apart from each other at predetermined intervals in the horizontal direction and the vertical direction. Specifically, the radiators 1101R1 to 1101R4 of the cone array antenna 1100 and the metal patches 1101-1 to 1101-4 are spaced apart at predetermined intervals to form a 2x2 cone array antenna.

Accordingly, the transceiver circuit 1250 may be configured to radiate a signal through the 2x2 cone array antenna 1100 to perform multiple input/output (MIMO). To this end, the transceiver circuit 1250 may be connected through the feeding units 1105-1 to 1105-4 of the 2x2 cone array antenna 1100.

Meanwhile, among the cone array antennas 1100 according to the present invention, the antennas 1100-3 and 1100-4 disposed at the lower portion are arranged by shifting a predetermined interval with respect to the cone antennas 1100-1 and 1100-2 disposed above Can be. Accordingly, interference between the cone array antennas 1100 may be reduced to increase the isolation between signals according to multiple input/output (MIMO).

In this regard, FIG. 6 is a conceptual diagram comparing isolation between cone array antennas of various structures according to the present invention. In this regard, FIG. 6(a) shows a structure in which the cone array antenna 1100 is formed symmetrically with each other. That is, metal patches 1101-1 and 1101-3 are formed on different sides of the cone radiators 1100R1 and 1100R3. Accordingly, the shorting pins 1102-1 and 1102-3 formed on the metal patches 1101-1 and 1101-2 are also disposed adjacent to each other. Accordingly, interference signals between the cone array antennas 1100 formed in a mutually symmetrical shape may be mutually canceled. In particular, since the shorting pins 1102-1 and 1102-3 are disposed adjacent to each other, a long signal path can be formed between the interference signals, so that the interference signals can cancel each other. In this regard, the degree of isolation between the cone antennas 1100-1 and 1100-3 has a value of 10 dB or more.

On the other hand, FIG. 6B shows a structure in which the cone array antenna 1100 is formed in the same arrangement structure. That is, metal patches 1101-1 and 1101-3 are formed on the same side of the cone radiators 1100R1 and 1100R3. Accordingly, the shorting pins 1102-1 and 1102-3 formed on the metal patches 1101-1 and 1101-3 are also disposed on the same side. Accordingly, there is a problem in that interference signals between the cone array antennas 1100 formed in the same arrangement structure are difficult to cancel each other. In this regard, the degree of isolation between the cone antennas 1100-1 and 1100-3 has a value of about 7dB.

Accordingly, the shorting pins 1102-1 and 1102-2 formed on the metal patches 1101-1 and 1101-2 are also disposed on the same side. Accordingly, there is a problem in that interference signals between the cone array antennas 1100 formed in the same arrangement structure are difficult to cancel each other.

Specifically, FIG. 7A shows a structure in which the cone array antenna 1100 is symmetrical with respect to the top and bottom, but is disposed at the same position in the left and right directions. On the other hand, FIG. 7B shows that among the cone array antennas 1100, the antennas 1100-3 and 1100-4 disposed at the bottom are shifted by a predetermined interval with respect to the cone antennas 1100-1 and 1100-2 disposed at the top.

Accordingly, the fourth cone antenna 1100-4 including the fourth metal patch 1101-4 is configured to operate up to a lower frequency band lower than the operating frequency of the remaining cone antennas 1100-1 to 1100-3. .

The fourth metal patch 1101-4 may be formed to have a larger size than other metal patches so that the fourth cone antenna 1100-4 operates up to a low frequency band. In addition, a shorting pin 1102-5 may be further provided at a position other than the shorting pin 1102-4 disposed in the upper center of the fourth metal patch 1101-4. According to current paths of different lengths formed by the plurality of shorting pins 1102-4 and 1102-5, the bandwidth characteristics of the fourth cone antenna 1100-4 may be improved.

Meanwhile, regardless of the shape of the metal patches of the plurality of cone antennas 1100-1 to 1100-4, the inner side shape of the metal patches 1101-1 to 1101-4 is a circular shape. I can. Specifically, the inner shape of the square patch corresponding to the fourth metal patch 1101-4 may be formed in a circular shape to correspond to the shape of the outline of the upper opening of the cone radiator 1100R4. Accordingly, a signal radiated from the fourth cone radiator 1100R4 may be formed to be coupled through the inside of the rectangular patch.

As described above, each of the metal patches 1101-1 to 1101-4 further includes feeders 1105-1 to 1105-4 in addition to the shorting pins 1102-1 to 1102-4. can do.

In this case, the number of fasteners 1104-1 to 1104-4 is not limited thereto, and may be variously changed according to an application. In addition to mechanical stability, the number of outer rims and fasteners for each radiator can be increased for multiple resonances in the low frequency band. In this way, in consideration of the number of outer rims and fasteners provided for each radiator, the corresponding cone antenna may be referred to as a “multi-wing structure”.

It may be placed in the upper area of (1100-3). In addition, one of the array antenna modules (that is, the second array antenna module ANT2) is a lower area of the second cone antenna 1100-2 disposed in the upper right and the fourth cone antenna 1100 disposed in the lower right. It can be placed in the upper area of -4).

Meanwhile, the first array antenna module ANT1 and the second array antenna module ANT2 may further include a transmission/reception circuit connected thereto in addition to the array antenna, respectively.

Meanwhile, FIGS. 9A and 9B are front views of a cone antenna having a Cone with single shorting pin structure according to various embodiments of the present disclosure. That is, FIGS. 9A and 9B show cone antennas implemented by one shorting pin by one radiator. Here, as shown in FIGS. 9A and 9B,

metal patches

1101 and 1101 ′ may be disposed only on one side of the cone radiator 1100R. In this regard, in the case of the circular patch 1101 of FIG. 9A, the inside of the metal patch 1101 may be formed in a circular shape to correspond thereto.

Meanwhile, the Cone with single shorting pin structure as shown in FIGS. 9A and 9B may be implemented by one shorting pin (or shorting support). Specifically, FIG. 8A shows a shape in which a circular metal patch is disposed on one side of an upper opening of the cone radiator. On the other hand, FIG. 8B shows a shape in which a rectangular metal patch is disposed on one side of the upper opening of the cone radiator.

Meanwhile, referring to FIGS. 9A and 9B, the cone antenna 1100 is formed between a first substrate as an upper substrate and a second substrate as a lower substrate. Meanwhile, the cone antenna 1100 may include

metal patches

1101, 1101 ′, 1101a and 1101b and a shorting pin 1102. Here, the metal patch 1101 may be formed in a peripheral area of one side of the upper aperture of the cone antenna 1100. In this regard, the metal patch 1101 may be formed on the first substrate. Here, the cone antenna 1100 may refer to only a hollow cone antenna or may refer to an entire antenna structure including the metal patch 1101.

Specifically, the

metal patches

1101, 1101 ′, 1101a, and 1101b may be formed in a peripheral region of the upper opening of the cone antenna 1100 and may be disposed on the first substrate. Accordingly, the metal patch 1101 may be disposed at a position spaced apart from the upper opening of the cone antenna 1100 in the z-axis by the thickness of the first substrate. In this way, when the metal patch 1101 is disposed on the first substrate, there is an advantage that the size of the cone antenna 1100 can be further reduced. Specifically, since a first substrate having a predetermined dielectric constant is disposed in an upper region of the cone antenna 1100 including the metal patch 1101, there is an advantage in that the size of the cone antenna 1100 can be further reduced.

Alternatively, the

metal patches

1101, 1101 ′, 1101a, and 1101b may be formed in a peripheral area of the upper opening of the cone antenna 1100 and may be disposed under the first substrate. Accordingly, the metal patch 1101 may be spaced apart from the upper opening of the cone antenna 1100 at a predetermined interval on the same plane on the z-axis. When the metal patch 1101 is disposed under the first substrate as described above, the first substrate may operate as a radome of the con antenna 1100 including the metal patch 1101. Accordingly, there is an advantage in that the cone antenna 1100 including the metal patch 1101 can be protected from the outside, and a gain of the cone antenna 1100 can be increased.

The shorting pin 1102 is configured to connect the

metal patches

1101, 1101', 1101a, 1101b and the ground layer GND formed on the second substrate. In this way, by the shorting pin 1102 configured to connect the metal patch 1101 and the ground layer GND formed on the second substrate, there is an advantage that the size of the cone antenna 1100 can be reduced. Meanwhile, the number of shorting pins 1102 may be one or two. A case in which the number of shorting pins 1102 is one may be most advantageous from the viewpoint of miniaturization of the cone antenna 1100. Accordingly, the shorting pin 1102 may be formed as a single shorting pin between the metal patch and the second substrate, which is a lower substrate. However, the number of shorting pins is not limited thereto, and two or more shorting pins may be used from the viewpoint of performance and structural stability of the cone antenna 1100. Depending on the application, some pins other than the shorting pin 1102 may be implemented as a non-metal supporting pin in a non-metal type.

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

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 signals through two or more cone antennas may be referred to as n Tx or n Rx according to 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. In this way, a case in which the transceiver circuit 1250 transmits or receives the first and second signals having the same data through two cone antennas may be referred to as a diversity mode.

Meanwhile, the shape of the metal patch 1101 may be configured in the form of a circular patch as shown in FIG. 9A.

In addition, the shape of the metal patch 1101 may be configured as a rectangular patch as shown in FIG. 9B. In this regard, the shape of the metal patch 1101 may be implemented in the form of a circular patch or an arbitrary polygonal patch in terms of antenna miniaturization and performance depending on the application. In this regard, it can be approximated to a circular patch shape as the degree of the polygon increases in an arbitrary polygonal patch shape.

Referring to FIG. 9A, the metal patch 1101 may be formed as a circular patch having an outer side shape of a circular shape. Meanwhile, the inner side shape of the circular patch may be formed in a circular shape so as to correspond to the shape of the outline of the upper opening. Accordingly, since the signal radiated from the cone antenna is formed to be coupled through the inside of the circular patch 1101, there is an advantage in that antenna performance can be optimized.

Referring to FIG. 9B, the metal patch 1101 ′ may be formed as a rectangular patch having an outer side shape of a square shape. Meanwhile, the inner side shape of the square patch may be formed in a circular shape so as to correspond to the shape of the outline of the upper opening. Accordingly, since the signal radiated from the cone antenna is formed to be coupled through the inside of the square patch 1101, there is an advantage in that antenna performance can be optimized.

In this regard, FIGS. 10A and 10B illustrate an electronic device including a cone antenna having a cone with two shorting pin structure according to an embodiment of the present invention. In this regard, the Cone with two shorting pin structure is a cone antenna implemented by two shorting pins (or shorting supports). Here, the structures of FIGS. 10A and 10B are not limited to the Cone with two shorting pin structure, and may be a Cone with single shorting pin structure. In this regard, one of the two support structures may be implemented as a shorting pin and the other as a non-metallic support. Specifically, one of the shorting pins 1102a of FIG. 10A may be replaced with a non-metallic support 1106. Accordingly, one of the non-metallic supports 1106 may be formed on a metal patch disposed on the other side.

Meanwhile, referring to FIGS. 4A to 10B, the cone antenna 1100a is formed between a first substrate as an upper substrate and a second substrate as a lower substrate. Meanwhile, the cone antenna 1100a may include a metal patch 1101a and a shorting pin 1102a. Here, the metal patch 1101a may be formed in a peripheral area of the upper aperture of the cone antenna 1100a. In this regard, the metal patch 1101 may be formed on the first substrate.

Meanwhile, the

metal patches

1101 and 1101a may be implemented as circular patches to surround the entire upper opening of the

cone antennas

1100 and 1100a. However, the present invention is not limited thereto, and the metal patch 1101a may be implemented as a circular patch surrounding a part of the upper opening of the cone antenna 1100a. Accordingly, the circular patch may be formed on both sides of the upper opening of the cone antenna 1100a or may be formed on one side.

Accordingly, in the cone antenna 1100a according to the present invention, the circular patch 1101a may be formed in the entire area so as to surround the entire area of the upper opening of the cone antenna 1100a. Specifically, a metal patch such as the circular patch 1101a may be disposed on both one side and the other side corresponding to the one side so as to surround the entire upper opening of the cone antenna.

Accordingly, the cone antenna 1100a including the symmetrical circular patch 1101a and the shorting pin 1102a may have a slightly increased overall size than when a metal patch disposed on only one side is provided. However, the cone antenna 1100a having the symmetrical circular patch 1101a and the shorting pin 1102a has an advantage that the radiation pattern is symmetrical and can be implemented with broadband characteristics.

Meanwhile, in the cone antenna 1100a according to the present invention, the circular patch 1101a may be formed only in a partial region so as to surround a partial region of the upper opening. Accordingly, there is an advantage of minimizing the size of the cone antenna 1100a including the metal patch 1101a.

Specifically, the metal patch 1101a may be formed in a peripheral region of the upper opening of the cone antenna 1100a and may be disposed on the first substrate. Accordingly, the metal patch 1101a may be disposed at a position spaced apart from the upper opening of the cone antenna 1100a in the z-axis by the thickness of the first substrate. In this way, when the metal patch 1101a is disposed on the first substrate, there is an advantage that the size of the cone antenna 1100a can be further reduced. Specifically, since a first substrate having a predetermined dielectric constant is disposed in an upper region of the cone antenna 1100 including the metal patch 1101a, there is an advantage that the size of the cone antenna 1100 can be further reduced.

Alternatively, the metal patch 1101 may be formed in a peripheral region of the upper opening of the cone antenna 1100a and may be disposed under the first substrate. Accordingly, the metal patch 1101a may be spaced apart from the upper opening of the cone antenna 1100a at a predetermined interval on the same plane on the z-axis. When the metal patch 1101a is disposed under the first substrate as described above, the first substrate may operate as a radome of the cone antenna 1100a including the metal patch 1101a. Accordingly, there is an advantage in that the cone antenna 1100a including the metal patch 1101a can be protected from the outside, and a gain of the cone antenna 1100a can be increased.

The shorting pin 1102a is configured to connect between the metal patch 1101a and the ground layer GND formed on the second substrate. As described above, the shorting pin 1102a configured to connect the metal patch 1101a and the ground layer GND formed on the second substrate has the advantage of miniaturizing the size of the cone antenna 1100a.

Meanwhile, the

metal patches

1101 and 1101a may be formed as circular patches having a circular shape in an outer side shape. Meanwhile, the inner side shape of the circular patch may be formed in a circular shape so as to correspond to the shape of the outline of the upper opening. Accordingly, since the signal radiated from the cone antenna is formed to be coupled through the inside of the circular patch 1101a, there is an advantage that antenna performance can be optimized.

Meanwhile, a resonance length may be formed by an opening of the metal patch 1101a having an opening size larger than that of the upper opening of the cone antenna. Accordingly, a signal radiated from the cone antenna 1100a may be coupled through the inside of the circular patch 1101a. Accordingly, there is an advantage in that the cone antenna 1100a can be miniaturized by the opening of the circular patch 1101a having a larger opening size than the upper opening of the cone antenna.

Meanwhile, the

metal patches

1101 and 1101b may be implemented as square patches to surround the entire upper opening of the

cone antennas

1100 and 1100b. However, the present invention is not limited thereto, and the metal patch 1101b may be implemented as a rectangular patch surrounding a part of the upper opening of the cone antenna 1100b. Accordingly, the square patch may be formed on both sides of the upper opening of the cone antenna 1100a or may be formed on one side.

Accordingly, in the cone antenna 1100a according to the present invention, the rectangular patch 1101b may be formed in substantially the entire area so as to surround the upper opening area of the cone antenna 1100b. In this regard, in order to reduce the size of the square patch 1101b, the square patch 1101b may not be formed in a region around the fastener 1104 supporting the cone antenna 1100b. Accordingly, the square patch 1101b may be disposed in the left area and the right area of the cone antenna 1100b, respectively.

In this regard, the metal patch 1101b may include a first metal patch 1101b1 and a second metal patch 1101b2. Specifically, the first metal patch 1101b1 may be formed on the left side of the upper opening to surround the upper opening of the cone antenna 1100b. In addition, the second metal patch 1101b2 may be formed on the right side of the upper opening to surround the upper opening of the cone antenna 1100b.

Accordingly, the first metal patch 1101b and the second metal patch 1101b2 are formed so that the metal pattern is separated, so that the total antenna size can be reduced. In this regard, when the first metal patch 1101b and the second metal patch 1101b2 are interconnected, the metal patch 1101b may partially operate as a radiator. Accordingly, due to the influence of the metal patch 1101b having a bandwidth narrower than that of the cone antenna 1100b, the bandwidth may be partially limited due to unwanted resonance.

In order to prevent such bandwidth limitation, the first metal patch 1101b and the second metal patch 1101b2 may be formed so that the metal pattern is separated. Accordingly, the cone antenna 1100b in which the metal pattern is separated by the first metal patch 1101b and the second metal patch 1101b2 may operate as a broadband antenna. Accordingly, the first metal patch 1101b and the second metal patch 1101b2 may not be formed in a region corresponding to the outer rim 1103 forming the upper opening.

Specifically, the square patch 1101b may be formed in a peripheral region of the upper opening of the cone antenna 1100b and may be disposed on the first substrate. Accordingly, the metal patch 1101b may be disposed at a position spaced apart from the upper opening of the cone antenna 1100b in the z-axis by the thickness of the first substrate. In this way, when the metal patch 1101b is disposed on the first substrate, there is an advantage that the size of the cone antenna 1100b can be further reduced. Specifically, since the first substrate having a predetermined dielectric constant is disposed in the upper region of the cone antenna 1100 including the metal patch 1101b, there is an advantage that the size of the cone antenna 1100b can be further reduced.

Alternatively, the rectangular patch 1101b may be formed in a peripheral region of the upper opening of the cone antenna 1100b and may be disposed under the first substrate. Accordingly, the metal patch 1101b may be spaced apart from the upper opening of the cone antenna 1100b at a predetermined interval on the same plane on the z-axis. When the metal patch 1101b is disposed under the first substrate as described above, the first substrate may operate as a radome of the cone antenna 1100b including the metal patch 1101b. Accordingly, there is an advantage in that the cone antenna 1100b including the metal patch 1101b can be protected from the outside, and a gain of the cone antenna 1100b can be increased.

The shorting pin 1102b is configured to connect between the metal patch 1101a and the ground layer GND formed on the second substrate. As described above, the shorting pin 1102a configured to connect the metal patch 1101a and the ground layer GND formed on the second substrate has the advantage of miniaturizing the size of the cone antenna 1100a.

The transceiver circuit 1250 may be connected to the cone antenna 1100b and control to emit a signal through the cone antenna 1100b. A detailed description in this regard is replaced with the description in FIG. 8.

Referring to FIG. 10B, the rectangular patch 1101b may be formed as a rectangular patch having an outer side shape of a square shape. Meanwhile, the inner side shape of the square patch may be formed in a circular shape so as to correspond to the shape of the outline of the upper opening. Accordingly, since the signal radiated from the cone antenna is formed to be coupled through the inside of the rectangular patch 1100b, there is an advantage that antenna performance can be optimized.

Meanwhile, a resonance length may be formed by a circular opening of the square patch 1101b having an opening size larger than that of the upper opening of the cone antenna. Accordingly, a signal radiated from the cone antenna 1100b may be coupled through the inside of the rectangular patch 1101b. Accordingly, there is an advantage in that the cone antenna 1100b can be miniaturized by the circular opening of the square patch 1101b having an opening size larger than that of the upper opening of the cone antenna.

On the other hand, the electronic device having the cone antenna according to the present invention, that is, the communication relay device has excellent reception performance in almost all directions through the cone antenna. Specifically, the radiation pattern of the cone antenna has excellent reception performance even at the bore site in the elevation direction. In this regard, FIG. 11A shows the radiation pattern for a symmetrical structure, such as a cone antenna with two shorting pins. On the other hand, FIG. 11B shows a radiation pattern for a structure such as a cone antenna having one shorting pin.

Referring to FIG. 11A, a cone antenna having two shorting pins has a problem in that reception performance is degraded because a null of a radiation pattern is generated at a bore site in a direction of an elevation angle. In order to solve this problem, in the present invention, through a structure in which the cone antenna 1110 is connected to one shorting pin 1102, the null of the radiation pattern can be removed from the boresite in the elevation direction. In this regard, referring to FIG. 9A, a cone antenna having one shorting pin includes a power supply unit 1105-a cone radiator 1100R-a metal patch 1101-a short pin 1102-a ground layer GND. To form a current path. In this way, through the asymmetric current path of the feed part 1105-the cone radiator 1100R-the metal patch 1101-the short pin 1102-the ground layer GND, the radiation pattern at the bore site in the elevation direction is null ( null) can be prevented from being generated.

Referring to FIG. 11B, in the cone antenna having one shorting pin, the null of the radiation pattern may be removed from the bore site in the elevation direction. Accordingly, in the present invention, there is an advantage that reception performance can be improved in almost all directions.
