โฆ Synopsis
Seueral formulas based on the cauity model and the transmission-line model are combined to produce closed-form expressions for calculating the input resonant resistance of probe-fed rectangular microstrip antenna elements with thick substrates. These apressions take into account the patch and substrate physical properties and the effect of sulface waue, radiation, conductor, and dielectric losses with their equivalent resistances. Experimental results are compared with computed results to demonstrate the accuracy and versatility of this apresswns.

Simple techniques haยจe been deยจeloped for eยจaluating mutual coupling coefficients between two identical probe-fed rectangular antenna elements with thick substrates.

Formulas based on the two-slot, the caยจity, and the surface current models to compute the far-field radiation patterns in both the E and H planes for rectangular microstrip antenna elements are studied and their ยจalidity assessed.

## Abstract In this paper, an efficient neural network model is suggested to determine the input resonant resistance of coaxial fed rectangular microstrip antennas (MSAs) with thin and thick substrates. The NN results are in good agreement with experimental results reported in literature. This meth
