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...
In this paper, a very electrically small canopy antenna is introduced. The canopy antenna radiates at ap 297Mhz with a Qratio ap 1.75. An active internal matching network is applied to this canopy antenna; over a 10% fractional bandwidth is obtained for this ESA (a ~ lambda/137).
