1. An antenna system for reducing by one half the number of antennas required by an adaptive array means to reject interference signals, said system comprising:

  • at least one antenna array means which includes at least two dipole element means; and

    phase shifter means coupled to recieve the output signal of the first terminal of the antenna array means for changing the phase of the output signal;

    where the output terminal of the phase shifter means and the second terminal of the antenna array means are each disposed to be coupled to different input terminals of the adaptive array such that direction of arrival phase information is retained;

    the said adaptive array means having a number of input terminal pairs that correspond to the number of antenna array means.
