Abstract: PURPOSE: A device for damping a radiated power of a duplex antenna is provided to damp a radiated power of a duplex antenna included in a communication terminal. CONSTITUTION: An antenna switch(110) connects an RF signal being transmitted/received from a wireless communication terminal to one antenna out of two antennas in accordance with a switch control signal being received from a control unit of the terminal. The first antenna(130) is used for a calling process, and the second antenna(140) is an additional antenna. Thus, a radiated power is applied from the first antenna(130) to the second antenna(140). When the communication terminal is a waiting status, the control unit controls the antenna switch(110) for selecting and connecting to the first antenna(130). When a call is set or a preliminary operation for setting a call is existed, the control unit controls the antenna switch(110) for selecting and connecting to the second antenna(140). If the second antenna(140) is selected, a damping circuit(120) damps and cuts-off a radiated power applied to the first antenna(130) from the second antenna(140) and a power amplifier. In case that the first antenna(130) is selected, the control unit decreases a damping amount. In case that the second antenna(140) is selected, the control unit increases a damping amount.
