发明名称 Angle diversity dual antenna system
摘要 <p>An angle diversity antenna system utilizes a first antenna, a second antenna, and a panel combiner coupled to the first and second antenna. In a transmit mode, the first and second antenna are coupled to a transmit sum channel of the panel combiner. In a receive mode, either the sum channel or a difference channel of the panel combiner is chosen as the active channel. By monitoring the sum channel and difference channel, the antenna system according to the present invention is able to select the channel which supplies the greatest signal strength. <IMAGE></p>
