Analysis of Microstrip Patch Antennas on Spherical Structures

The paper presents the program for calculating input impedance and radiation pattern of spherical patch antennas. The patches can be of circular or quasi-rectangular shape, and they are fed by a coaxial line. The multilayer spherical structure is rigorously taken into account by using proper Green’ ; s functions, and the electric field integral equation is numerically solved by applying moment method This problem is solved in spectral domain, i.e. for each value of spectral variables only one-dimensional problem has to be solved. In order to avoid numerical problems a new definition of vector-Legendre transformation is implemented and normalized Legendre polynomials are used in solution procedure.
