Abstract :
This paper uses the electric surface current method to determine the radiation pattern and input impedance of cylindrical-rectangular microstrip antennas with a superstrate. The fields are solved taking into account both dielectric layers and the metallic cylinder through the proper Green´s function. It also discusses the effects of varying the thickness and dielectric permittivity of the superstrate.
