Wireless communication apparatus and antenna device
A wireless communication apparatus includes a first communication system, and a second communication system configured to transmit a transmission signal in a communication frequency band which is the same or substantially the same as that of the first communication system and at an electric power which is stronger than that of a reception signal of the first communication system. The first communication system includes a feeder circuit having a resonant frequency, the resonant frequency being within the communication frequency band if a reception signal of the first communication system is input, and the resonant frequency being out of the communication frequency band if a transmission signal of the second communication system is input.
