Patent ID: 8633863

Claim:
A modal antenna system, comprising: a modal antenna, and a memory-enhanced spatial filter for use with the modal antenna; said modal antenna comprising: an antenna radiator disposed above a circuit board forming an antenna volume therebetween; a first frequency tuning parasitic element connected to said circuit board and positioned between the circuit board and the antenna radiator within the antenna volume, and a second beam steering parasitic element positioned outside of the antenna volume and adjacent to the antenna radiator; said memory-enhanced spatial filter for use with the modal antenna comprising: an adaptive processor adapted to receive a plurality of input radio signals and deliver weighted signals therefrom; a plurality of memory modules each being adapted to store one of said input radio signals; a plurality of signal combiners, each of said signal combiners being connected to one of said memory modules and further connected to said adaptive processor, the signal combiners each being adapted to combine the corresponding input radio signal from the connected one of said memory modules with the weighted signal from said adaptive processor to form an output signal, the signal combiners collectively forming a plurality of output signals; and a summing circuit connected to each of said signal combiners and adapted to sum each of the output signals from said signal combiners to form an enhanced signal, the summing circuit being further adapted to resample the enhanced signal through said adaptive processor for actively reconfiguring the enhanced signal and adjusting said weight signals; wherein a bank of said input radio signals is stored in said memory and used for enhanced signal processing for use with a single modal antenna.
