Abstract :
The far field radiation patterns of a wraparound microstrip antenna mounted on a sphere are studied theoretically. The radiator is replaced by an assumed surface current distribution. The effects of the dielectric layer and the metallic sphere are rigorously taken into account by a spectral domain Green´s function formulation. Some practical results with different dielectric substrate thickness and radius of sphere are illustrated.<>
