Abstract :
The radiation field produced by v.o.r. antennas consisting of Alford loops located above a circular conducting ground plane is investigated theoretically and experimentally. Geometrical theory of diffraction is applied to obtain the theoretical expressions for the far field produced by such an antenna. Within the range of approximation, the agreement between theory and experiment has been found to be very good.
