Abstract

This paper presents the design and development of an X-band microstrip gap-coupled sectoral patch array antenna for application in wireless systems. A novel concept of bandwidth enhancement is considered for gap-coupled sectoral microstrip patch array antenna, which uses one active receiving antenna and multiple parasitic elements with finite ground plane. The parasitic elements give the possibility of creating a directive antenna beam. A broadband of 1 GHz with a return loss of −50 dB has been achieved in X-band along with a directivity of 11.1 dBi and reduced side lobe level to −23.7 for 3 dB angular width.
