A high performance low-profile antenna array with low sidelobe level (SLL) and optimum beamwidth is in general preferred in several communication related applications. In this paper a planar microstrip array antenna with low SLL up to-20 dB and high gain performance is designed for 10 GHz. The dimensions of patch antenna is tapered to achieve low SLL. The results for patch array with individual feed and a common feed are presented.
