For example, there are functions of data and voice communication, taking pictures and videos through a camera, recording voice, playing music files through a speaker system, and outputting images or videos 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 providing visual content such as broadcasting and video or television programs.

As shown, when the rear cover 103 is coupled to the rear case 102, a part of the side surface of the rear case 102 may be exposed. In some cases, when the rear case 102 is combined, the rear case 102 may be completely covered by the rear cover 103. Meanwhile, the rear cover 103 may be provided with an opening for exposing the camera 121b or the sound output unit 152b to the outside.

In addition, two or more display units 151 may exist depending on the implementation form of the electronic device 100. In this case, in the electronic device 100, a plurality of display units may be spaced apart or integrally disposed on one surface, or may be disposed on different surfaces, respectively.

The display unit 151 may include a touch sensor that senses a touch on the display unit 151 so as to receive a control command by a touch method.

The first and second operation units 123a and 123b may be employed in any manner as long as the user operates while receiving a tactile feeling such as touch, push, and scroll. In addition, the first and second manipulation units 123a and 123b may also be employed in a manner in which the first and second manipulation units 123a and 123b are operated without a user's tactile feeling through proximity touch, hovering touch, or the like.

Meanwhile, the electronic device 100 may be provided with a fingerprint recognition sensor for recognizing a user's fingerprint, and the controller 180 may use fingerprint information detected through the fingerprint recognition sensor as an authentication means.

The microphone 122 is configured to receive a user's voice and other sounds. The microphone 122 may be provided in a plurality of locations and configured to receive stereo sound.

The interface unit 160 becomes a passage through which the electronic device 100 can be connected to an external device. For example, the interface unit 160 is a connection terminal for connection with other devices (eg, earphones, external speakers), a port for short-range communication (eg, an infrared port (IrDA Port), a Bluetooth port (Bluetooth Port), a wireless LAN port, etc.], or at least one of a power supply terminal for supplying power to the electronic device 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card such as a subscriber identification module (SIM) or a user identity module (UIM), or a memory card for storing information.

Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover 103, or a case including a conductive material may be configured to function as an antenna.

Meanwhile, four or more antennas disposed on the side of the terminal may be implemented to support MIMO. In addition, when the 5G wireless communication module 112 operates in a millimeter wave (mmWave) band, since each of the plurality of antennas is implemented as an array antenna, a plurality of array antennas may be disposed in the electronic device.

The terminal body is provided with a power supply unit 190 (refer to FIG. 1A) for supplying power to the electronic device 100. The power supply unit 190 may include a battery 191 built in the terminal body or configured to be detachable from the outside of the terminal body.

Hereinafter, a structure of a multiplex 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 obvious 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.

2 shows a configuration of a wireless communication unit of an electronic device capable of operating 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. In addition, the electronic device may further include a modem 400 and an application processor 500. Here, the modem 400 and the application processor AP 500 may be physically implemented in one chip, and may be implemented in a logically and functionally separate 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) 410 to 440 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 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 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 in one chip.

Meanwhile, the application processor (AP) 500 is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP) 500 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 the idle mode, the application processor AP 500 may control the RFIC 250 through the modem 300 as follows. For example, if the electronic device is in the idle mode, the RFIC through the modem 300 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) 500 may control the modem 300 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) 500 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) 500 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 power of the electronic device is equal to or greater than a threshold, the modem 300 may be controlled to select an optimal wireless interface. For example, the application processor (AP, 500) 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, 500) 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, 500) 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 one transmitting and 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 components can be controlled by the integrated transceiver, the front-end components can be integrated more efficiently than when the transmission/reception system is separated for each communication system.

In addition, when separated for each communication system, 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.

Meanwhile, by integrating the transmitting and receiving unit and the receiving unit, it is possible to implement two different wireless communication systems with a single antenna using a transmitting and receiving antenna. At this time, 4x4 MIMO can be implemented using four 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 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 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) so as 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. Further, 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 having array antennas operating in different bands according to the present invention equipped with a multiple transmission/reception system as shown in FIG. 2 will be described below.

In the 5G communication system according to the present invention, the 5G frequency band may be a higher frequency band than the Sub6 band. For example, the 5G frequency band may be a millimeter wave band, but is not limited thereto and may be changed according to an application.

3 shows an example of a configuration in which a plurality of antennas of an electronic device according to the present invention can be disposed. Referring to FIG. 3, a plurality of antennas 1110a to 1110d or 1150B may be disposed on the rear surface of the electronic device 100. Alternatively, a plurality of antennas 1110S1 and 1110S2 may be disposed on the side of the electronic device 100.

Meanwhile, referring to FIG. 2, a plurality of antennas ANT 1 to ANT 4 may be disposed on a side or rear surface of the electronic device 100. Here, each of the plurality of antennas ANT 1 to ANT may be configured as an array antenna to perform beamforming in a millimeter wave band. Each of a plurality of antennas (ANT 1 to ANT) composed of a single antenna and/or a phased array antenna for use of a wireless circuit such as the transceiver circuit 250 is mounted on the electronic device 100 Can be.

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 an array antenna. The electronic device can communicate with the base station through any one of the plurality of antennas 1110a to 1110d. Alternatively, the electronic device may perform multiple input/output (MIMO) communication with a base station through two or more of the plurality of antennas 1110a to 1110d.

Meanwhile, according to the present invention, at least one signal may be transmitted or received through a plurality of antennas 1110S1 and 1110S2 on the side of the electronic device 100. Unlike illustrated, at least one signal may be transmitted or received through the plurality of antennas 1110S1 to 1110S4 on the side of the electronic device 100. In this regard, each of the plurality of antennas 1110S1 to 1110S4 may be configured as an array antenna. The electronic device can communicate with the base station through any one of the plurality of antennas 1110S1 to 1110S4. Alternatively, the electronic device may perform multiple input/output (MIMO) communication with the base station through two or more of the plurality of antennas 1110S1 to 1110S4.

Meanwhile, the present invention may transmit or receive at least one signal through a plurality of antennas 1110a to 1110d, 1150B, 1110S1 to 1110S4 on the back and/or side of the electronic device 100. In this regard, each of the plurality of antennas 1110a to 1110d, 1150B, and 1110S1 to 1110S4 may be configured as an array antenna. The electronic device can communicate with the base station through any one of the plurality of antennas 1110a to 1110d, 1150B, and 1110S1 to 1110S4. Alternatively, the electronic device may perform multiple input/output (MIMO) communication with the base station through two or more of the plurality of antennas 1110a to 1110d, 1150B, and 1110S1 to 1110S4.

Hereinafter, an electronic device having a double polarized antenna operating in a millimeter wave band according to the present invention will be described.

In this regard, FIG. 4 shows a perspective view of an electronic device having a double polarized antenna according to the present invention. Meanwhile, FIG. 5 shows a top view of an electronic device having a double polarized antenna according to the present invention. Further, FIG. 6 shows a side view of an electronic device having a double polarized antenna according to the present invention.

4 to 6, the electronic device includes a first antenna element 1110 and a second antenna element 1120. In addition, the electronic device further includes a transceiver circuit 1210 and a control unit 1250.

The first antenna element 1110 is configured to radiate a first signal having a first polarization from a side surface of the electronic device. On the other hand, the second antenna element 1120 is configured to emit a second signal having a second polarization different from the first polarization from the side. Here, the first polarization and the second polarization may be horizontal polarization (HP) and vertical polarization (VP), respectively. However, the shape of the first polarization wave and the second polarization wave is not limited thereto, and may be a substantially orthogonal linear polarization (LP) type according to an application. In addition, the shape of the first polarization wave and the second polarization wave may be a substantially orthogonal circular polarization (CP) or elliptical polarization (EP) shape depending on the application.

The transceiver circuit 1210 is connected to the first antenna element 1110 and the second antenna element 1120. In addition, the transceiver circuit 1210 controls to radiate at least one of the first signal and the second signal through at least one of the first antenna element 1110 and the second antenna element 1120.

In this regard, the transceiver circuit 1210 may simultaneously emit (transmit and/or receive) a first signal and a second signal through the first antenna element 1110 and the second antenna element 1120, respectively. Here, the electronic device may perform a multiple input/output (MIMO) mode to transmit or receive different data using the first signal and the second signal. To this end, the electronic device may acquire channel information through a process of exchanging or measuring control information with a base station. For example, if the level of interference between the horizontal polarization and the vertical polarization is less than a certain level, the electronic device may perform a multiple input/output (MIMO) mode to transmit or receive different data using the first signal and the second signal. have. In this regard, the controller 1250 may demodulate and decode different data received through the first received signal and the second received signal. In addition, the controller 1250 may code and modulate different data and transmit them to the base station through the first transmission signal and the second transmission signal.

On the other hand, if the level of interference between the horizontal polarization and the vertical polarization is higher than a certain level, the electronic device may perform a diversity mode to transmit or receive the same data using the first signal and the second signal. In this regard, the electronic device may obtain channel information through a process of exchanging or measuring control information with the base station. For example, if the level of interference between the horizontal polarization and the vertical polarization is higher than a certain level, the electronic device may transmit or receive the same data using the first signal and the second signal by performing a diversity mode. . In this regard, the controller 1250 may demodulate and decode data through a signal having a high signal quality among the first and second received signals. Alternatively, the controller 1250 may demodulate and decode data through a signal in which the first and second received signals are optimally combined. In addition, the controller 1250 may code and modulate the same data and transmit the same data to the base station through the first transmission signal and the second transmission signal.

Meanwhile, referring to FIGS. 4 to 6, at least a partial area of the second antenna element 1120 may be disposed to be parallel to the first antenna element 1110. Accordingly, as described above, by arranging at least a portion of the second antenna element 1120 to be parallel to the first antenna element 1110, there is an advantage that the height of the second antenna element 1120 can be reduced. have. Accordingly, when the second antenna element 1120 is disposed on the side of the electronic device, a problem in that the height of the electronic device is increased can be solved.

In this regard, the first antenna element 1110 is a printed antenna element printed on a circuit board 1100 disposed parallel to a top surface and a back surface of the electronic device in the electronic device. It can be implemented with (printed antenna element). Accordingly, the first antenna element 1110 is configured to transmit and receive a horizontal polarization (HP) signal.

On the other hand, the second antenna element 1120 may be implemented as an antenna element formed perpendicular to a circuit board disposed parallel to the top and back surfaces of the electronic device. Do. Accordingly, the second antenna element 1120 is configured to transmit and receive a vertical polarization (VP) signal.

Accordingly, the first antenna element 1110 and the second antenna element 1120 may be referred to as a horizontal antenna and a bent vertical antenna, respectively.

Meanwhile, the first antenna element 1110 may be formed as a dipole antenna, and the second antenna element 1120 may be formed as a monopole antenna. However, the present invention is not limited thereto, and both the first antenna element 1110 and the second antenna element 1120 may be formed of a dipole antenna according to an application. Alternatively, both the first antenna element 1110 and the second antenna element 1120 may be formed as monopole antennas.

Meanwhile, the first antenna element 1110 and the second antenna element 1120 may be configured to operate in the same frequency band of the millimeter wave band in order to support multiple input/output (MIMO). In this regard, since the antenna types of the first antenna element 1110 and the second antenna element 1120 are different, electrical characteristics between them cannot be completely the same. Accordingly, the first antenna element 1110 as a dipole antenna and the second antenna element 1120 as a monopole antenna have similar electrical characteristics, that is, impedance matching characteristics, radiation efficiency, and radiation pattern in the same frequency band, which is at least some of the millimeter wave bands. It can be implemented to have.

In this regard, in order to reduce the size of the antenna in the existing LTE band, a monopole antenna may be preferred. However, in the 5G band, particularly the millimeter wave band, a dipole antenna having a larger size may be preferred from the viewpoint of radiation efficiency.

On the other hand, when both the first antenna element 1110 and the second antenna element 1120 are formed of a monopole antenna, it is advantageous in terms of radiation efficiency. However, interference may occur between monopole antennas of the same type.

Accordingly, an object of the present invention is to reduce interference between dual polarized antennas. To this end, the first antenna element 1110 and the second antenna element 1120 may be implemented as a dipole antenna and a monopole antenna, which are different types of antennas. Meanwhile, when a vertical type antenna such as the second antenna element 1120 is implemented as a dipole antenna, the height (thickness) of the side of the electronic device may increase. Accordingly, in the present invention, the second antenna element 1120 as a vertical polarized antenna may be implemented as a monopole antenna, and the first antenna element 1110 as a horizontal polarized antenna may be implemented as a dipole antenna.

As described above, the reason that the first antenna element 1110 and the second antenna element 1120 are disposed horizontally and vertically on the circuit board 1100, respectively, is to form horizontal polarization and vertical polarization. Meanwhile, a dipole antenna generally radiates a signal through the side of a circuit board. On the other hand, monopole antennas generally radiate signals through the front surface of a circuit board.

Meanwhile, in the present invention, the first antenna element 1110 and the second antenna element 1120 are disposed horizontally and vertically on the circuit board 1100, respectively. Accordingly, the first antenna element 1110 as a dipole antenna forms a radiation pattern in a direction parallel to the electronic device, that is, in the lateral direction of the circuit board 1100. In addition, the second antenna element 1120, which is a monopole antenna, forms a radiation pattern in a direction parallel to the electronic device by ground, that is, in the lateral direction of the circuit board 1100.

Accordingly, in the present invention, there is an advantage that both the radiation patterns of the first antenna element 1110 and the second antenna element 1120 can be formed in the lateral direction of the circuit board 1100. Through this, even when the first signal is transmitted and/or received through the first antenna element 1110, and the second signal is transmitted and/or received through the second antenna element 1120, the radiation pattern is the same. There is an advantage that it can be formed in a direction.

Accordingly, even when the electronic device rotates without moving, there is an advantage in that signal transmission and reception characteristics can be optimized only by changing the antenna polarization without beamforming. For example, when changing from the first antenna element 1110 to the second antenna element 1120 according to the rotation of the electronic device, only the polarization may be changed while forming the radiation pattern in the same direction.

Meanwhile, in order to implement the second antenna element 1120, which is a vertically polarized antenna, as a monopole antenna, a ground plane needs to be formed vertically. Accordingly, as shown in FIGS. 4 to 6, a ground wall 1130 formed perpendicular to the front surface of the circuit board 1100 disposed in the electronic device and operating as a ground for the second antenna element 1120. ) May be further included.

Meanwhile, the ground wall 1130 is configured to include a first ground 1131 and a second ground 1132. As described above, the first ground 1131 and the second ground 1132 formed vertically have the advantage of reducing the side height (thickness) of the electronic device.

The first ground 1131 is formed perpendicular to the entire surface of the circuit board 1100. That is, the first ground 1131 may be formed perpendicular to the front surface of the first circuit board 1101 corresponding to the front surface of the multilayer circuit board 1100.

Meanwhile, the second ground 1132 is vertically connected to the first ground 1131 and is formed parallel to the front surface of the circuit board 1100. In this regard, the second ground 1132 may not cover the second conductive member 1122 of the second antenna element 1120 and may cover only a partial region (ie, the upper portion of the circuit board 1100 ). This is because when the second ground 1132 is formed to cover the second conductive member 1122, there is a restriction that the second ground 1132 must be disposed above the second conductive member 1122.

In this regard, when the second ground 1132 is disposed above the second conductive member 1122, signal radiation by the second conductive member 1122 is directed to the bottom of the electronic device. Accordingly, signal radiation by the second conductive member 1122 may affect the first antenna element 1110. Accordingly, interference between the first antenna element 1110 and the second antenna element 1120 may be increased. Accordingly, in the present invention, the second ground 1132 is not formed in a peripheral region of the second conductive member 1122 so as not to operate as a ground for the second conductive member 1122.

Meanwhile, referring to FIG. 6, the height of the ground wall 1130 may be formed substantially the same as the height of the second antenna element 1120. In this way, by limiting the height of the ground wall 1130, it is possible to improve the impedance matching characteristic of the second antenna element 1120 while minimizing the thickness of the electronic device. To this end, the distance d between the second ground 1132 and the second antenna element 1120 may be optimized so that the impedance characteristic in the corresponding frequency band is optimized.

In this regard, the height of the ground wall 1130 is not limited to the shape of FIG. 6. Depending on the application, the height of the ground wall 1130 may be formed higher than the height of the second antenna element 1120. Accordingly, it is possible to improve the radiation efficiency of the second antenna element. When the height of the second antenna element 1120 is the same as the height of the ground wall 1130, the antenna performance may be degraded at the end of the second antenna element 1120. In this regard, this is because the second antenna element 1120 may not operate entirely as a monopole antenna according to a finite ground effect at the edge of the second antenna element 1120.

On the other hand, when the height of the ground wall 1130 is formed higher than the height of the second antenna element 1120, as described above, the second ground 1132 is the second conductive member 1122 of the second antenna element 1120. ) Can be formed not to cover. That is, the second ground 1132 may not cover the second conductive member 1122 of the second antenna element 1120, but may cover only a partial area (ie, the upper portion of the circuit board 1100 ).

Meanwhile, a detailed shape and electrical characteristics of the second antenna element, which is a vertically polarized antenna according to the present invention, are as follows. In this regard, FIG. 7 shows the shape of the vertically polarized antenna according to the present invention. Specifically, FIG. 7(a) shows a'C' type bending antenna as shown in FIGS. 4 to 6. On the other hand, FIG. 7(b) shows a'T' type bending antenna.

Referring to FIGS. 4 to 6 and 7A, the second antenna element 1120 may be configured to include a first conductive member 1121 and a second conductive member 1122. In this regard, the first conductive member 1121 is formed perpendicularly to the circuit board 1110 disposed parallel to the top surface and the back surface of the electronic device in the electronic device. Here, the first conductive member 1121 is connected to the feeder 2 of the circuit board 1110 and receives an RF signal from the feeder 2.

Here, the meaning of a conductive member is broadly interpreted as including a conductive pattern. Accordingly, the first and second

conductive members

1121 and 1122 may be interpreted as first and second

conductive patterns

1121 and 1122. In this regard, the first and

second antenna elements

1110 and 1120 may be implemented as a metal frame like a conductive member. In addition, the first and

second antenna elements

1110 and 1120 may be implemented as a conductive pattern or a metal pattern printed on a substrate such as a conductive strip.

In addition, the second conductive member 1122 is vertically connected to the first conductive member 1121 and disposed in parallel with the first antenna element 1120. Specifically, the second conductive member 1122 is disposed substantially parallel to the feeder 1 of the first antenna element 1110. In addition, the second conductive member 1122 is disposed substantially parallel to the feeder 2 of the second antenna element 1120. As described above, there is an advantage in that the space in which the vertically polarized antenna is disposed can be reduced by the second antenna element 1120 formed by the first conductive member 1121 and the second conductive member 1122.

Meanwhile, referring to FIGS. 4 to 6 and 7A, the second antenna element 1120 includes a first conductive member 1121, a second conductive member 1122, and a third conductive member 1123. Can be configured to In this regard, the first conductive member 1121 is formed perpendicularly to the circuit board 1110 disposed parallel to the top surface and the back surface of the electronic device in the electronic device. Here, the first conductive member 1121 is connected to the feeder 2 of the circuit board 1110 and receives an RF signal from the feeder 2.

In addition, the second conductive member 1122 is vertically connected to the first conductive member 1121 and disposed in parallel with the first antenna element 1120. Specifically, the second conductive member 1122 is disposed substantially parallel to the feeder 1 of the first antenna element 1110. In addition, the second conductive member 1122 is disposed substantially parallel to the feeder 2 of the second antenna element 1120.

In addition, the third conductive member 1123 is vertically connected to the second conductive member 1122 and disposed parallel to the first conductive member 1121. Specifically, the third conductive member 1123 is disposed substantially perpendicular to the first antenna element 1110. In addition, the third conductive member 1123 is disposed substantially perpendicular to the feeder 2 and the second conductive member 1122 of the second antenna element 1120. As described above, the first conductive member 1121 and the third conductive member 1123 may be formed by bending in different directions to be disposed in a side surface space of the electronic device. Accordingly, the second antenna element 1120 formed by the first conductive member 1121 to the third conductive member 1123 may further reduce an arrangement space in which the vertically polarized antenna is disposed.

Meanwhile, referring to FIG. 7B, the second antenna element 1120 may be configured to include a first conductive member 1121 and a second conductive member 1122b. In this regard, the first conductive member 1121 is formed perpendicularly to the circuit board 1110 disposed parallel to the top surface and the back surface of the electronic device in the electronic device. Here, the first conductive member 1121 is connected to the feeder 2 of the circuit board 1110 and receives an RF signal from the feeder 2.

In addition, the second conductive member 1122b is vertically connected to the first conductive member 1121 and disposed parallel to the first antenna element 1120. Specifically, the second conductive member 1122b extends in both directions along one axis of the side surface in a horizontal direction with the side surface of the electronic device. Here, the center of the second conductive member 1122b is connected to the first conductive member 1121 so that the radiation pattern may be formed in a symmetrical shape. Meanwhile, the second conductive member 1122b is disposed substantially parallel to the first antenna element 1110 and disposed substantially perpendicular to the feeder of the first antenna element 1110. In addition, the second conductive member 1122b is disposed substantially perpendicular to the feeder 2 of the second antenna element 1120. As described above, there is an advantage in that the space in which the vertically polarized antenna is disposed can be reduced by the second antenna element 1120 formed by the first conductive member 1121 and the second conductive member 1122b.

Meanwhile, the second antenna element 1120 may be configured to include a first conductive member 1121, a second conductive member 1122b and a third conductive member 1123b. In this regard, the first conductive member 1121 is formed perpendicularly to the circuit board 1110 disposed parallel to the top surface and the back surface of the electronic device in the electronic device. Here, the first conductive member 1121 is connected to the feeder 2 of the circuit board 1110 and receives an RF signal from the feeder 2.

In addition, the second conductive member 1122b is vertically connected to the first conductive member 1121 and disposed parallel to the first antenna element 1120. Specifically, the second conductive member 1122b extends in both directions along one axis of the side surface in a horizontal direction with the side surface of the electronic device. Here, the center of the second conductive member 1122b is connected to the first conductive member 1121 so that the radiation pattern may be formed in a symmetrical shape. Meanwhile, the second conductive member 1122b is disposed substantially parallel to the first antenna element 1110 and disposed substantially perpendicular to the feeder of the first antenna element 1110. In addition, the second conductive member 1122b is disposed substantially perpendicular to the feeder 2 of the second antenna element 1120.

Further, the third conductive member 1123b is vertically connected to the second conductive member 1122b. Specifically, the third conductive member 1123 may be vertically connected to the second conductive member 1122b at both ends of the second conductive member 1122b. In addition, the third conductive member 1123b is disposed substantially perpendicular to the feeder 2 and the second conductive member 1122b of the second antenna element 1120. As described above, the first conductive member 1121 to the third conductive member 1123b may be formed by bending in different directions so as to be disposed in the side surface space of the electronic device. Accordingly, the second antenna element 1120 formed by the first conductive member 1121 to the third conductive member 1123b has the advantage of further reducing an arrangement space in which the vertically polarized antenna is disposed.

The'T'-type bending antenna of FIG. 7(b) has the advantage of further reducing an arrangement space in which the vertically polarized antenna is disposed than the'C'-type bending antenna of FIG. 7(a). In this regard, when the size of the electronic device is the same, the'T' type bending antenna of FIG. 7(b) is disposed farther from the side end of the electronic device than the'C' type bending antenna of FIG. 7(a). Can be. Accordingly, the'T' type bending antenna of FIG. 7(b) has the advantage of being less affected by the usage state of the electronic device. For example, in an electronic device such as a mobile terminal, there is little change in characteristics according to a user's grab.

On the other hand, the'C' type bending antenna of FIG. 7(a) has an advantage in that electrical characteristics such as vertical polarization characteristics are better than the'T' type bending antenna of FIG. 7(b). Accordingly, in the present invention, the second antenna element 1120 is implemented in a form in which the'C' type bending antenna of FIG. 7(a) and the'T' type bending antenna of FIG. 7(b) are combined. It can be implemented to include a switch. Specifically, a first switch disposed between the first conductive member 1121 and the second conductive member 1122, and second and third disposed on both sides of the first conductive member 1121 and the second conductive member 1122b. It may include a switch.

Accordingly, when it is determined that the difference in the level of the received signal is large according to the user's grab or the surrounding environment, the first conductive member 1121 and the second conductive member 1122b are connected using the second and third switches. Thus, the'T' type bending antenna of FIG. 7(b) can be configured.

On the other hand, if it is determined that the difference in the received signal level is small depending on the surrounding environment, the first conductive member 1121 and the second conductive member 1122 are connected using a first switch to obtain'C' of FIG. 7(a). It is possible to optimize the electrical characteristics by configuring a bending antenna. Accordingly, in the present invention, there is an advantage in that an antenna performance optimized for a situation can be obtained through a T'type bending antenna and a C'type bending antenna that can be adaptively changed according to different environments.

Meanwhile, according to the present invention, beamforming for optimal signal transmission and reception may be implemented by implementing the first antenna element 1110 and the second antenna element 1120 as array antennas. In addition, according to the present invention, beamforming for optimal signal transmission and reception can be implemented together with multiple input/output (MIMO) by implementing the first antenna element 1110 and the second antenna element 1120 as a plurality of array antennas. In this regard, FIG. 8A shows an electronic device in which a horizontally polarized antenna and a vertically polarized antenna according to the present invention are configured with a plurality of array antennas. On the other hand, FIG. 8B is a diagram illustrating that a horizontal polarized antenna and a vertical polarized antenna according to the present invention are disposed on one side of an electronic device.

8A and 8B, the first antenna element 1110 and the second antenna element 1120 are composed of a first array antenna ANT1 and a second array antenna ANT2 in which a plurality of antenna elements are arranged. I can. In this regard, the first array antenna ANT1 and the second array antenna ANT2 can be expanded to 2, 4, 6, 8, 16, etc. depending on the application.

8A and 8B, the first array antenna ANT1 and the second array antenna ANT2 may be implemented as 2x2 array antennas to enable beamforming in horizontal and vertical directions. Alternatively, the first array antenna ANT1 and the second array antenna ANT2 may be implemented as a 4x1 array antenna so that beamforming is possible only in a horizontal direction.

Meanwhile, referring to FIGS. 8A and 8B, the electronic device includes a first antenna element 1110 and a second antenna element 1120. In addition, the electronic device further includes a transceiver circuit 1210 and a control unit 1250. Here, the transmission/reception unit circuit 1210 may include a plurality of transmission unit circuits, that is, first and second transmission/

reception unit circuits

1211 and 1212, and may be referred to as

RFICs

1211 and 1212.

Meanwhile, the electronic device may further include an IFIC 1220 configured to control the plurality of

transmitter circuits

1211 and 1212. Meanwhile, the controller 1250 may control the first and

second transceiver circuits

1211 and 1212 through the IFIC 1220. Here, the controller 1250 may be referred to as the baseband processor 1250 or the modem 1250.

4 to 6, 8A, and 8B, the first antenna element 1110 is configured to radiate a first signal having a first polarization from a side surface of the electronic device. On the other hand, the second antenna element 1120 is configured to emit a second signal having a second polarization different from the first polarization from the side. Here, the first polarization and the second polarization may be horizontal polarization (HP) and vertical polarization (VP), respectively. However, the shapes of the first polarization and the second polarization are not limited thereto, and as described above, any orthogonal polarization may be used.

The first transceiver circuit 1211 is connected to the first array antenna ANT1 and the second array antenna ANT2. In addition, the first transceiver circuit 1211 controls to radiate at least one of the first signal and the second signal through at least one of the first array antenna ANT1 and the second array antenna ANT2.

Meanwhile, the first transmission/reception unit circuit 1211 may control the first array antenna ANT1 and the second array antenna ANT2 to form beams in different directions, thereby reducing a level of mutual interference.

According to the present invention, the first antenna element 1110 and the second antenna element 1120 are implemented as a plurality of array antennas, as described above, to implement beamforming for optimal signal transmission and reception along with multiple input/output (MIMO). .

In this regard, a third array antenna ANT3 and a fourth array antenna ANT4 corresponding to the first array antenna ANT1 and the second array antenna ANT2 may be further disposed on the other side of the electronic device. Meanwhile, the first to fourth array antennas ANT1 to ANT4 may be disposed on four different side surfaces of the electronic device as illustrated in FIG. 3. However, according to the present invention, multiple input/output (MIMO) can be implemented by disposing antennas having different double polarizations on one side of an electronic device. Accordingly, in the present invention, it is not necessary to arrange all antennas on four different side surfaces of the electronic device. As shown in FIG. 8A, there is an advantage that an array antenna only needs to be provided on two different sides of the electronic device.

Meanwhile, the second transceiver circuit 1212 is connected to the third array antenna ANT3 and the fourth array antenna ANT4. In addition, the second transceiver circuit 1212 controls to radiate at least one of the third signal and the fourth signal through at least one of the third array antenna ANT3 and the fourth array antenna ANT4.

The control unit 1250 is configured to be connected to the first transmission/reception unit circuit 1211 and the second transmission/reception unit circuit 1212. Meanwhile, the control unit 1250 may control to transmit or receive a signal through the most optimal array antenna through the first transmission/reception unit circuit 1211 and the second transmission/reception unit circuit 1212.

Specifically, when the horizontal movement of the electronic device is greater than the vertical movement, the controller 1250 may control to emit a signal through an array antenna having the same polarization as follows. In this case, the controller 1250 may control to search for an optimal beam in the horizontal direction through the antenna rather than changing the polarization of the antenna. Accordingly, the control unit 1250 may control to emit a signal through the array antenna of the same polarization by changing the operating states of the first transmission/reception unit circuit 1211 and the second transmission/reception unit circuit 1212.

For example, the controller 1250 may transmit and receive signals through the second transceiver circuit 1212 from the first array antenna ANT1, which is a horizontal polarization antenna, through the first transceiver circuit 1211. Accordingly, the control unit 1250 may transmit and receive signals through the third array antenna ANT3 having the same horizontal polarization as before through the second transceiver circuit 1212. Accordingly, the control unit 1250 may turn off the first transceiver circuit 1211 and turn on the second transceiver circuit 1212. Accordingly, there is an advantage in that the beam formation can be adaptively responded to the movement of the terminal and changes in the surrounding environment by using array antennas disposed at different positions on the side of the electronic device.

Alternatively, the controller 1250 may transmit and receive signals through the second transceiver circuit 1212 from the second array antenna ANT2, which is a vertically polarized antenna, through the first transceiver circuit 1211. Accordingly, the control unit 1250 may transmit and receive signals through the fourth array antenna ANT4 having the same vertical polarization as before through the second transceiver circuit 1212. Accordingly, the control unit 1250 may turn off the first transceiver circuit 1211 and turn on the second transceiver circuit 1212. Accordingly, there is an advantage in that the beam formation can be adaptively responded to the movement of the terminal and changes in the surrounding environment by using array antennas disposed at different positions on the side of the electronic device.

Alternatively, the controller 1250 may transmit and receive signals through the first transceiver circuit 1211 from the third array antenna ANT3, which is a horizontal polarized antenna, through the second transceiver circuit 1212. Accordingly, the control unit 1250 may transmit and receive signals through the first array antenna ANT1 having the same horizontal polarization as before through the first transmission/reception unit circuit 1212. Accordingly, the control unit 1250 may turn on the first transmission/reception unit circuit 1211 and turn off the second transmission/reception unit circuit 1212. Accordingly, there is an advantage in that the beam formation can be adaptively responded to the movement of the terminal and changes in the surrounding environment by using array antennas disposed at different positions on the side of the electronic device.

Alternatively, the controller 1250 may transmit and receive signals through the first transceiver circuit 1211 from the fourth array antenna ANT4, which is a vertically polarized antenna, through the second transceiver circuit 1212. Accordingly, the control unit 1250 may transmit and receive signals through the second array antenna ANT2 having the same vertical polarization as before through the first transmission/reception unit circuit 1211. Accordingly, the control unit 1250 may turn on the first transmission/reception unit circuit 1211 and turn off the second transmission/reception unit circuit 1212. Accordingly, there is an advantage in that the beam formation can be adaptively responded to the movement of the terminal and changes in the surrounding environment by using array antennas disposed at different positions on the side of the electronic device.

On the other hand, when the vertical movement of the electronic device is greater than the horizontal movement, the controller 1250 may control to radiate a signal through array antennas of different polarizations as follows. In this case, the controller 1250 may control the polarization of the antenna to be changed once rather than searching for an optimal beam through the same polarized antenna. Accordingly, the control unit 1250 may control to emit signals through array antennas having different polarizations. In this case, switching between the first transmission/reception unit circuit 1211 and the second transmission/reception unit circuit 1212 does not occur.

For example, the control unit 1250 may transmit and receive signals from the first array antenna ANT1, which is a horizontal polarization antenna, through the second array antenna ANT2, which is a vertical polarization antenna through the first transceiver circuit 1211. I can. Accordingly, the control unit 1250 may transmit and receive signals through the second array antenna ANT2 having a different vertical polarization than before through the same first transmission/reception unit circuit 1211. Accordingly, the control unit 1250 maintains the first transmission/reception unit circuit 1211 in an ON state and the second transmission/reception unit circuit 1212 in an OFF state, thereby minimizing and configuring a circuit topology change. There is an advantage in that it is possible to minimize changes in the state of a component.

Alternatively, the control unit 1250 may transmit and receive signals from the second array antenna ANT2, which is a vertical polarization antenna, through the first array antenna ANT1, which is a horizontal polarization antenna through the first transceiver circuit 1211. I can. Accordingly, the control unit 1250 may transmit and receive signals through the first array antenna ANT1 having a horizontal polarization different from the previous one through the same first transmission/reception unit circuit 1211. Accordingly, the control unit 1250 maintains the first transmission/reception unit circuit 1211 in an ON state and the second transmission/reception unit circuit 1212 in an OFF state, thereby minimizing and configuring a circuit topology change. It has the advantage of minimizing changes in the state of the part.

Alternatively, the control unit 1250 may transmit and receive signals from the third array antenna ANT3, which is a horizontal polarized antenna, through the fourth array antenna ANT4, which is a vertically polarized antenna through the second transceiver circuit 1212. I can. Accordingly, the controller 1250 may transmit and receive signals through the fourth array antenna ANT4 having a different vertical polarization than before through the same second transceiver circuit 1212. Accordingly, the control unit 1250 maintains the first transmission/reception unit circuit 1211 in an OFF state and the second transmission/reception unit circuit 1212 in an ON state, thereby minimizing and configuring the circuit topology change. It has the advantage of minimizing changes in the state of the part.

Alternatively, the control unit 1250 may transmit and receive signals from the fourth array antenna ANT4, which is a vertical polarization antenna, through the third array antenna ANT3, which is a horizontal polarization antenna through the second transceiver circuit 1212. I can. Accordingly, the controller 1250 may transmit and receive signals through the third array antenna ANT3 having a horizontal polarization different from the previous one through the same second transceiver circuit 1212. Accordingly, the control unit 1250 maintains the first transmission/reception unit circuit 1211 in an OFF state and the second transmission/reception unit circuit 1212 in an ON state, thereby minimizing and configuring the circuit topology change. It has the advantage of minimizing changes in the state of the part.

In the above, a structure of a double polarized antenna operating in a millimeter wave band according to the present invention has been described. Hereinafter, the technical effect of the structure of the dual polarized wave antenna operating in the millimeter wave band according to the present invention will be compared with the control group.

In this regard, FIG. 9 is a comparison between a vertically polarized antenna and a ground wall structure having a bending structure according to the present invention and a case without a bending structure. In this regard, a vertically polarized antenna having a bending structure and a dual polarized antenna having a ground wall structure according to FIGS. 4 to 6 and 9(b) may be configured as follows.

The first antenna 1110 is configured to radiate a first signal having a first polarization from a side surface of the electronic device. Meanwhile, the second antenna 1120 is configured to emit a second signal having a second polarization different from the first polarization by being substantially perpendicular to the first antenna 1110. Here, the first polarization and the second polarization may be horizontal polarization (HP) and vertical polarization (VP), respectively. However, the shapes of the first polarization and the second polarization are not limited thereto, and as described above, any orthogonal polarization may be used.

The transceiver circuit 1210 is configured to be connected to the first antenna 1110 and the second antenna 1120. Also, the transceiver circuit 1250 may control to radiate at least one of the first signal and the second signal through at least one of the first antenna 1110 and the second antenna 1120.

In this regard, referring to FIGS. 4 to 6 and 9(b), at least a partial area of the second antenna 1120, that is, the second

conductive members

1122 and 1122b, is the first antenna 1110. It is placed parallel to. Accordingly, there is an advantage that the height of the antenna module can be reduced by 50% or more compared to the structure of FIG. 9(a) through the vertically polarized antenna of the bending structure according to the present invention.

In addition, the bending structure according to the present invention can be applied to a ground wall structure together with a vertically polarized antenna. In this regard, the ground wall 1130 may be formed perpendicular to the front surface of the circuit board 1100 disposed in the electronic device to operate as a ground for the second antenna 1120.

Meanwhile, the second ground 1132 is vertically connected to the first ground 1131 and is formed parallel to the front surface of the circuit board 1100. In this regard, the second ground 1132 may not cover the second conductive member 1122 of the second antenna 1120, but may cover only a partial area (ie, the upper portion of the circuit board 1100 ). This is because when the second ground 1132 is formed to cover the second conductive member 1122, there is a restriction that the second ground 1132 must be disposed above the second conductive member 1122.

In this regard, when the second ground 1132 is disposed above the second conductive member 1122, signal radiation by the second conductive member 1122 is directed to the bottom of the electronic device. Accordingly, signal radiation by the second conductive member 1122 may affect the first antenna 1110. Accordingly, interference between the first antenna 1110 and the second antenna 1120 may be increased. Accordingly, in the present invention, the second ground 1132 is not formed in a peripheral region of the second conductive member 1122 so as not to operate as a ground for the second conductive member 1122.

Meanwhile, referring to FIGS. 6 and 9B, the height of the ground wall 1130 may be formed substantially the same as the height of the second antenna element 1120. In this way, by limiting the height of the ground wall 1130, it is possible to improve the impedance matching characteristic of the second antenna 1120 while minimizing the thickness of the electronic device.

Referring to FIG. 12B, the height of the ground wall 1130 may be formed substantially equal to the height of the second antenna element 1120. In this way, by limiting the height of the ground wall 1130, it is possible to improve the impedance matching characteristic of the second antenna 1120 while minimizing the thickness of the electronic device. To this end, the distance d between the second ground 1132 and the second antenna 1120 may be optimized so that the impedance characteristic in the corresponding frequency band is optimized.

Here, port 2 means port 2 of the second antenna 1120 which is a vertically polarized antenna.

structures

1 and 2 of FIG. 13B, inflection points, that is, multiple resonance points, are formed.
