Abstract : Two circular array antennas 2 ft in diameter operating in S-band are described. One array has its radiating elements vertically polarized and the other has its radiating elements oriented at 45 degrees to detect both linear polarizations. Both arrays are fed with an R-2R parallel-plate lens feed system. Measurement results include radiation patterns, cross-polarization data, and gain, impedance, and mutual-coupling measurements.
