Theoretical and experimental studies of the driving-point impedance of corner-reflector antennas

The corner-reflector has been widely used to increase the directivity of antennas. When excited by a tilted dipole, it is also capable of producing circularly polarized radiation. The driving-point impedance of this antenna, however, has not been adequately dealt with in the literature. A method for calculating this parameter is presented based on the method of images. Numerical values are given for the case when the driven element is a half-wave dipole. The experimental results for the driving-point impedance measurement also are presented and compared with the theoretical predictions.
