Abstract :
This paper presents an analysis of radiation from a cylindrical-rectangular microstrip patch antenna loaded with a superstrate and an air gap between the substrate and the superstrate, using the full-wave approach and the electric surface current model. Numerical results are presented in the form of normalized radiation patterns for various thicknesses of the air gap and also for superstrates made of lossy dielectric material, to show the effects of these on the radiation from the antenna.
