β¦ Synopsis
Formulas available in the literature for the design of the physical properties of rectangular microstrip antenna elements are discussed, and their validity is assessed. Their variations have been experimentally
examined by analyzing a set of newly designed antenna elements with substrates satisfying the criterion h I 0.0815A0 for 2.22 5 E~ I 10.2, where A, is the free-space wauelength, h i s the thickness, and sr is the relative permittivity of the dielectric substrate. New formulas that can determine the antenna physical properties and the effective dielectric constant are empirically determined.

## Abstract This letter presents the closedβfrom formulas for determining the patch dimensions of electrically thin and thick rectangular microstrip antennas. The presented formulas constructed by utilizing a differential evolution algorithm become very useful as computerβaided design (CAD) models
Formulas based on the two-slot, the ca¨ity, 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 ¨alidity assessed. Three closed-form formulas are presented for the calculation of the r
