Design and Simulation of Dual-polarized Non-planar Conformal Phased Array Antenna

In this paper, a non-planar conformal dual-polarized phased array antenna is proposed. The design of non-planar conformal antenna and optimized simulations are presented. The antenna design is based on a dual-polarized patch antenna element with vertical orthogonal baluns. The antenna element is backed by a compact cavity, to reduce the inter-element mutual coupling and to enhance the scanning performance of the curved conformal array. The proposed array achieves a wide fractional bandwidth of over 20%, when scanning up to ±45° in E and H planes. The validity of design is confirmed by simulation outcomes of 10 × 10 array model.
