Abstract

In this paper, the cavity model of a microstrip patch antenna in conjunction with the reciprocity theorem is used to develop a fast analytical solution for the radiation field of a microstrip patch antenna loaded with an engineered magnetic superstrate and to investigate the effect of the artificial superstrate on improving the gain and radiation pattern of the printed patch antenna. The broadside coupled split ring resonator (SRR) inclusions are used in the design of the engineered magnetic superstrate. The proposed antenna configuration has been designed, fabricated, and measured. A good agreement is observed between the analytical solution, numerical simulations and measurement results.
