Modal Antenna Array For Interference Mitigation

Modal Antenna Array For Interference Mitigation

A modal antenna array is described where modal antenna elements capable of generating multiple radiation modes are used to form array radiation patterns. Nulls in the array radiation pattern can be formed and positioned by proper modal antenna element mode selection, with these nulls used to provide...

description A modal antenna array is described where modal antenna elements capable of generating multiple radiation modes are used to form array radiation patterns. Nulls in the array radiation pattern can be formed and positioned by proper modal antenna element mode selection, with these nulls used to provide interference suppression or mitigation. The shift in array radiation pattern maxima generated by modal element mode selection can be used to improve communication system link quality by optimizing array radiation pattern characteristics. Specifically, a ring or circular array configuration is described where a simplified common feed port can be implemented to feed multiple modal antenna elements used to form the array. A switch can be used to connect or disconnect one modal element from the array, with this feature providing additional unique array beam states. The modal array can be commanded via a look-up table or algorithm.
