Efficient design of finite conformal antenna arrays using VSIE formulation and P-FFT method

Abstract

A rigorous and effective analysis of finite conformal microstrip antenna array of arbitrary shape is presented using volume-surface integral equation (VSIE) formulation and Precorrected-fast fourier transform method (P-FFT) method where combined conducting and dielectric materials are considered. Three typical conformal arrays including cylindrical, spherical and conical arrays with thin dielectric sheets are considered. Microstrip-line and probe feed methods are used to excite the arrays.
