Abstract

PURPOSE:To obtain higher antenna gain, by taking the transmission gain smaller when the level is greater and taking it greater when the level is smaller, through the detection of the reception input level for the pilot signal coming into the element antenna. CONSTITUTION:The transmission signal is weighted according to the recption level with a gain control section 34 and retransmission is made from an antenna element 31 again via a transmission signal transmission line 37. The control section 34 performs smaller weighting when the reception signal level is greater and greater weighting when the reception signal level is smaller respectively. The reception signal transmission line 35 transmits the input level of the pilot signal of the element 31.
