Abstract :
Spherical arrays present a natural choice if complete hemispherical coverage with nearly constant beam width is needed. In this article, circular stacked-patch antennas embedded in a multilayer spherical structure are analyzed using the spectral-domain approach and the moment method. The influence of structure radius on input impedance and radiation pattern is investigated. The results confirm the importance of rigorous analysis of curved patch antennas. Furthermore, a laboratory model is built to validate the developed program. The agreement between measured and calculated results is good
