COMMUNICATION APPARATUS

摘要

A communication apparatus wherein oscillation of a power amplifier, which is a problem due to having a conductor for suppressing influence of noise to a chip antenna, is eliminated. The communication apparatus is provided with a chip antenna (2) for capturing radio waves of a desired frequency; a RF circuit (3) , which is mounted on a printed wiring board (1) and converting the received signals inputted from the chip antenna (2) into low frequency signals; a digital circuit (4), which is mounted on the printed wiring board (1) and demodulates the low frequency received signals inputted from the RF circuit (3); a conductor (5), which is arranged between the chip antenna (2) and the digital circuit (4) and extends to a position at a prescribed height from the printed wiring board (1), with one end connected to the ground conductor of the printed wiring board (1); and a radio wave absorber (13) added to the conductor (5).
