Abstract :
A reflector antenna utilizing three planar reflectors and a 3/4λ-unipole radiator has been used to increase the gain of the two-dimensional corner reflector antenna. The calculation of the antenna parameters were based on the image and electromotive force (EMF) methods. The method of moments is used for calculating the input impedance, gain and radiation patterns for two cases. In the first case continuous grounded conducting plane reflectors were used with the method of images. In the second case grided type plane reflectors consisting of parallel wires of suitable radii separation and length are used directly without the method of images. A good agreement between the results is indicated
