Radiation pattern of spherical array of rectangular microstrip patches

A program for calculating the radiation pattern of spherical arrays consisting of quasi-rectangular patches is presented. The problem is solved in the spectral domain, i.e. for each value of spectral variable only a one-dimensional problem has to be solved. A general algorithm for calculating Green´s functions is used in the program, therefore the patches can be printed on or embedded in a multilayer spherical structure. Two different types of array grids are investigated: icosahedron grid and quasi-rectangular grid.
