In this paper a short backfire antenna fed by an electromagnetic coupled patch (EMCP) operating at X-band is constructed and its performance is experimentally investigated and reported. The antenna is excited in the TM10 -mode. The resonant frequency is also measured and its value is compared with the predicted values as a mutual check of the experimental data. The experimental results indicate a remarkable improvement in the radiation pattern as well as in the gain and a noticeable increment in the bandwidth of the backfire antenna as compared with those of a single patch microstrip radiator.

Keywords: Backfire antenna, electromagnetic coupled patch feed element, X-band
