Disclosed is a wireless receiving apparatus, whereby inter-antenna interference can be reduced without inducing an increase of a mounting area due to an increase of the number of antennas, and the number of RFIC input terminals, circuit scale and power consumption can be reduced. In the wireless receiving apparatus (100), when a receiving antenna (110-1) and a down-converter (130) are connected with a multiplexer (120) therebetween, a capacity control unit (190-2) controls the capacity value of the capacity-variable parasitic element (180-2) connected to the receiving antenna (110-2) such that the communication capacity of the receiving antenna (110-1) is maximum. Furthermore, when the receiving antenna (110-2) and the down-converter (130) are connected with the multiplexer (120) therebetween, the capacity control unit (190-1) controls the capacity value of the capacity-variable parasitic element (180-1) connected to the receiving antenna (110-1) such that the communication capacity of the receiving antenna (110-2) is maximum.
