AbstractA simple, compact and single element rectangular microstrip antenna with three pairs of shorting plates has been proposed and investigated experimentally for broad impedance bandwidth and improved cross polarized (XP) radiation compared to maximum co-polarized (CO) gain without affecting the co-polarized radiation pattern. Around 25–40 dB isolation between copolarized radiation to cross polarized radiation (CO-XP isolation) along with 1.32 GHz impedance bandwidth is achieved with the proposed structure. The present structure is very simple and easy to manufacture and provides high CO-XP isolation over entire angular range around the broadside direction. Moreover, the present structure is free from back radiation in terms of XP fields. The present investigation provides an insightful, visualization-based understanding of concurrent improvement in impedance bandwidth and the XP radiation characteristics with the present structure.
