Abstract

A reconfigurable beam shape patch antenna (RBS-PA) is proposed in this paper. The RBS-PA antenna which consists of two rectangular elements is fed by a 50Ω microstrip feed line. A feed network technique is implementing to combine both radiating elements. The PIN diode switch is positioned at the transmission line at the ideal location. The activation of certain PIN diode switches configuration would then determine the beam shape angle and main lobe magnitude (dB). The RBS-PA is capable of shaped its radiated beam to 9.9dB and 6.7dB. All design and simulations have been carried out using CST Microwave Studio. This antenna is a promising candidate to be installed for a WiFi and WiMAX smart antenna system.
