Abstract
A wideband cavity backed slot antenna is designed for automotive-borne monopulse radar applications. A rectangular slot is used to realise broad bandwidth; the slot is backed by a cavity, and the vertical walls of the cavity are implemented by discrete vias; and the slot is fed by a microstrip line. The proposed antenna is compact, robust, fully planar and easy to integrate. A two-element array is fabricated and tested. Measured input impedance is matched to 50 ?? within band [2.61 GHz, 3.44 GHz] (27.5% bandwidth); and monopulse beam-scanning is successfully demonstrated.
