摘要：
In this article, a rigorous full-wave analysis for determining the resonant frequency and half-power bandwidth of inverted circular microstrip patch antenna is presented. Green's functions of the structure are determined in Hankel transform domain. Galerkin's is used in the resolution of the electric field integral equation. The TM set modes issued from the cavity model theory are used to expand to unknown current on the patch. The validity of the results is tested by comparing results with the experimental data. Also, numerical results for the variation of the resonant characteristics of the structure for high-order mode, and for several values of substrates thickness are presented.
