Abstract
Disclosed is an ultra high frequency radio communication apparatus having: a receiver antenna; a transmitter antenna; an IC chip being electrically connected to the receiver antenna and the transmitter antenna; a substrate on which the receiver antenna, the transmitter antenna and the IC chip are mounted; an input terminal for inputting to the IC chip a base band input signal; an output terminal for outputting a base band output signal from the IC chip; and a control signal terminal for inputting a control signal for controlling the IC chip to the IC chip. The IC chip is placed in a shielding space such that the cut-off frequency of the shielding space is higher than the frequency of a carrier signal for radio communication.
