ABSTRACT:
Disclosed is an antenna system having a first antenna directed to receive a desired signal wave and a second antenna directed to receive only an interference signal wave superposed on the desired signal wave. Both signals received by the first and second antennas are combined and the amplitude and phase shift necessary for the second antenna signal to cancel the interference signal component existing in the first antenna signal is calculated from the combined signal. By combining the controlled second antenna signal with the first antenna signal, the desired reception signal having an improved S/N ratio can be obtained.
