Abstract
In this paper, the input impedance and radiation pattern of spherical rectangular patch antennas are studied. The electric field integral equation is numerically solved by applying the method of moments where the multilayer spherical structure is rigorously considered, using the spectralโdomain algorithm for calculating Green's functions. In order to avoid numerical problems, a modified vectorโLegendre transformation and normalized Legendre polynomials are defined and applied to the solution procedure. ยฉ 2003 Wiley Periodicals, Inc.
