Abstract
A communication device which solves a new problem, that is, a power amplifier has oscillation caused by providing a conductive body which reduces the effects of the noise on a chip antenna, includes: a chip antenna which catches radio waves of a desired frequency; an RF circuit which is implemented on a printed wiring board and which converts received signals input from the chip antenna to a low frequency; a digital circuit which is implemented on the printed wiring board and which demodulates the received signals in a low frequency input from the RF circuit; a conductive body which is extended between the chip antenna and the digital circuit while being maintained at a certain height from the printed wiring board, and which has an end connected to a ground conductive body of the printed wiring board; and a radio wave absorption body which is attached to the conductive body.
