Method for Modeling of Cavity-Backed Conformal Array Antenna

A method for modeling of cavity-backed conformal array antenna is proposed to precisely design arbitrary-shaped conformal antenna with low profile. The method is based on meshing tools which can obtain units’ position information and normal direction. The antenna designed by the method shows high uniformity in units compared with installation method with flexible materials and lower profile while the units’ cavities are embedded in the carrier. The arrangement of units is chosen as quasi-rectangular in order to obtain better radiation patterns. An arbitrary-shaped conformal array antenna is modeled and simulated. The results reach the expected target and show that the method is feasible and effective.
