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 × 8 circular patch antenna elements with a hybrid feed‐line network providing dual‐polarization function and high isolation (∼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. © 2009 Wiley Periodicals, Inc.
