Abstract :
A reflector antenna utilizing three planar reflectors and a 3/4 λ-unipole radiator is proposed. Calculations based on image- and EMF-methods predict that the gain is about 5 dB greater than that of the two-dimensional corner reflector antenna, and that the input impedance is roughly between 50 and 75 Ω. Experiments conducted on the three-dimensional corner reflector antenna with rectangular corners confirmed the predicted properties and also showed the sidelobe in the electric plane being suppressed by the effect of diffraction. This effect is explained by the calculated radiation pattern of 3/4 λ-unipole on conducting half plate
