Analysis of Spherical Arrays of Microstrip Antennas Using Moment Method in Spectral Domain and G1DMULT
The input and mutual impedances of rectangular microstrip patches mounted on a multilayer spherical structure are studied in the paper. The multilayer spherical structure is rigorously taken into account using proper Green’ s functions calculated by the G1DMULT algorithm, and the electric field integral equation is numerically solved by applying the moment method. The 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 difficulties a modified vector-Legendre transformation and normalized Legendre polynomials are defined and applied to the solution procedure. The influence of the structure radius as well as of deviation from the spherical symmetry on input impedance is studied. A laboratory model is built to test different configurations of patch antennas and to validate the developed program.
