ELECTRONIC DEVICE COMPRISING MULTIPLE ANTENNAS

Abstract: an electronic device is provided. the electronic device includes a first antenna, a second antenna, a third antenna, a first radio frequency front end (rffe) connected to the first antenna, the first rffe including a duplexer passing a first signal in a downlink frequency range of a first frequency band and a second signal in an uplink frequency range of the first frequency band, a second rffe connected to the second antenna, the second rffe including a filter passing the first signal, a third rffe connectable to the second antenna or the third antenna, the third rffe including another duplexer passing a third signal in a downlink frequency range of a second frequency band and a fourth signal in an uplink frequency range of the second frequency band, memory storing one or more computer programs; and one or more processors comprising processing circuitry communicatively coupled to the first antenna, the second antenna, the third antenna, the first rffe, the second rffe, third rffe, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to connect the third rffe to the second antenna from among the second antenna and the third antenna to transmit the fourth signal while the second signal is transmitted via the first antenna, while the third rffe is connected to the second antenna, identify a defined event, and based on the defined event, connect the third rffe to the third antenna from among the second antenna and the third antenna to transmit the fourth signal while the second signal is transmitted.
