Abstract:
1. An antenna diversity system for radio reception comprising: a) a receiver; b) a plurality of antennas; c) a plurality of antenna feed lines forming at least one input signal path coupled to said plurality of antennas; d) a high frequency line coupled to said receiver; e) an antenna diversity module disposed external to said receiver and coupled to said plurality of antenna feed lines and to said high frequency line, said antenna diversity module comprising: f) an evaluation circuit which evaluates a quality of the reception signal and which is in communication with said at least one addressable logic signal selection switch; wherein if an interference occurs in a summed signal, said at least one evaluation circuit detects said interference and signals said addressable logic signal selection switch to select a different coordinated setting of a switching position; said system further comprising an electronic control device having a memory, for coordinated setting of discrete phase rotation angles φ
