A phased array antenna is designed for multifunction phased array radar simulation test bed. Effect of element pattern, mutual coupling between elements, phase quantization, amplitude and phase error and elements failure rates on array pattern are discussed. Target angle measurement and side lobe cancelling, in order to reduce jamming power through side lobes, is illustrated in this antenna. Also antenna beam width is broadened with different methods and compared with narrow beam characteristics. It is shown that, for special broadening factors, beam broadening may lead to a better coverage and power efficiency relative to narrow beam antenna.
