COMMUNICATIVE TRANSCEIVER USING ADAPTIVE DIRECTIONALITY ANTENNA

摘要

PURPOSE: A communicative transceiver using an adaptive directionality antenna is provided to increase the intensity of received signals and the mount of noise by radiating the RF power to a cellular phone station or another station. CONSTITUTION: A communicative transceiver using an adaptive directionality antenna includes two individual antennas(102,102'), an antenna pattern generation circuit, a switch(220), and a switch operator. The antennas are connected to the transceiver in order to receive the first signal from a base station. The antenna pattern generation circuit is connected to one of the antennas in order to generate a plurality of antenna patterns. The switch is used for selecting one pattern to provide the maximum intensity of the first signal. The switch operator is used for operating the switch to select one of plural antenna patterns.
