MATCHING DEVICE FOR A HF ANTENNA

摘要

The invention relates to a high frequency antenna tuning device. The antenna is connected to a power transmitter, which periodically supplies power signals at predetermined high frequencies. For each frequency, the tuning device comprises a tuning capacitor connected to a switch. These switches are connected to control means, which are in turn connected to identification outputs of the frequencies of the signals supplied by the generator. The device also comprises means for detecting power signals transmitted by the antenna, so as to prevent any switching throughout the duration of a power transmission by the antenna on one of the predetermined frequencies.
