A Method to Synthesize the Multiple‐Pattern Frequency‐Invariant Conformal Arrays

Abstract

This paper presents a method to synthesize the multiple‐pattern frequency‐invariant conformal arrays for the first time. In this method, the extended generalized matrix pencil method is applied to obtain the optimized linear arrays. Then with the help of the quasi‐conformal transformation optics, the conformal arrays are designed by employing the inhomogeneous metamaterials. A set of numerical simulations on Taylor pattern, pencil‐beam pattern and flat‐beam pattern is shown to demonstrate the results. © 2022 Institute of Electrical Engineers of Japan.
