    a controller configured to switch the transmit circuit and the receive circuit from transmitting and receiving wireless communications via the first antenna to transmitting and receiving wireless communications via the second antenna in response to detecting;

    a first receive power level of the first antenna is less than a second receive power level of the second antenna;

    a difference between the second receive power level and the first receive power level is greater than a first threshold; and

    the difference between the second receive power level and the first receive power level added to a difference between a second transmit power limit of the second antenna and a first transmit power limit of the first antenna is greater than a second threshold.
