Novel Active FET Circular Patch Antenna Arrays for Quasi-Optical Power Combining

摘要

This paper discusses two dimensional planar arrays of weakly coupled activecircular patch antennas suitable for quasioptical power combiners. A novel radiating element that has low cross polarization is described. A two dimensional array analysis was developed to address radiation pattern and phase problems. Equivalent isotropic radiated power levels of 1.5 W for a two by two FET array and 3.8 w for a two by four FET array have been obtained at X band.
