Abstract
- A wideband and dual-polarization antenna array with high efficiency and high isolation is proposed. In order to achieve the desired performance, a wideband radiating element and a full-corporate waveguide feed network are employed in the design. In particular, ${{E}}-plane waveguides are utilized for the feed-network configuration so as to suppress wave leakage between adjacent layers when the antenna is fabricated via conventional machining techniques. The operational mechanism is presented and a \text16 \times \text16 antenna array is tested for verification. Experimental results show that the bandwidths of VSWR < \text2.0 for both of the polarizations are about 17.1% (12.45–14.78 GHz) and the isolation between the two polarization ports is better than 39.5 dB. In addition, more than 70% antenna efficiency with higher than 29.4 dBi gain is achieved over the operational bandwidth. [ABSTRACT FROM PUBLISHER]
