摘要：

A dual-polarized X-band array antenna for advanced airborne weather hazard monitoring radar applications is presented. This low-profile array is composed of 8 x 8 circular patch antenna elements with a hybrid feed-line network, providing dual-polarization function and high isolation (similar to 40 dB) between H- and V-ports. The antenna operation bandwidth is from 9.9 to 10 GHz. and has a radiation gain of 19 dBi and cross-polarization of 31 dB. The array can be easily placed on the aircraft fuselage because of its ultra-thin thickness (0.13 mm), ultra-lightweight, and conformal structure, and it has potential applications in radar surveillance, remote sensing, and wireless communications.
