Wide-Scanning Conformal Linear Phased Array

In this paper, a wide-scanning linear conformal phased array is presented. The antenna element is mainly composed of a dipole, a Marchand balun, a shorting-pin, two directors and frequency selective surface (FSS) structure. Besides, the proposed array is implemented using the 1×12 radiating elements that are mounted onto a curved wing surface. Simulated results show that the array can achieve VSWR less than 3.0 over 20% bandwidth, within a wide-scanning range of ±60° in E plane. In addition, the array has a gain reduction of less than 0.86dBi when scanning to ±60° in the horizontal direction.
