For example, the first duplexer 132-1 separates the frequency of the signal transmitted through the first antenna 116-1 from the frequency of the signal transmitted through the first antenna 116-1, thereby receiving and transmitting the received signal. Interference between signals can be prevented.

When the first power amplifier 133-1 transmits a first signal (or a transmission signal) to the base station 10, the first power amplifier 133-1 amplifies the first signal and thus the first duplexer 132-1 and the first coupler 131-1. Can be sent to.

In the case of the second antenna 116-2, since the I / Q value is P24 in the constellation diagram, the processor 140 may detect that the user's hand is in contact with the electronic device 100.

In the above embodiment, since the external object detected through the first antenna 116-1 is an ear jack, the electronic device 100 may not sweep the phases of the antennas. On the other hand, since the external object detected by the second antenna 116-2 is a human body, the electronic device 100 may sweep the phases of the antennas. In this case, the electronic device 100 may sweep the phases of the antennas so that the direction of the beam pattern is formed away from the body.
