Recent Results on Conformal Antennas at the University of Zagreb

The purpose of this paper is to present different programs, developed recently at the University of Zagreb, which rigorously analyze different types of cylindrical and spherical arrays. The analysis approach is based on solving the electric field integral equation via moment method approach. The three-dimensional problem is reduced to a spectrum of one-dimensional problems by applying the Fourier transformation in the directions where the structure is homogeneous. Consequently, the elements of the moment method matrix and the excitation vector are calculated in the spectral domain. The kernel of the integral operator is a Green's function, which is different for different structures. In order to analyze various structures we have developed an algorithm, called G1DMULT, that calculates spectral-domain Green's functions of multilayer planar, circular-cylindrical and spherical structures.
