Coplanar waveguide slot-coupled patch antenna electronic scanning array for on-the-move SATCOM

The design of a Ka-band coplanar waveguide slot-coupled patch antenna ESA with integrated MEMS phase shifters has been described above. The incorporation of MEMS phase shifters into the ESA design results in a compact, efficient uplink mechanism for a future Army satellite communication system. A control board for biasing the phase shifters and initiating beam steering will be incorporated into the final array. The details of this design and the measured beam steering results of the fully-fabricated demonstrator array will be presented at the 2009 IEEE Antennas and Propagation Society Conference.
