The effectiยจe design and analysis of microstrip antennas presupposes the quantitatiยจe knowledge of the effects of the physical and mechanical properties of the patch, the ground plane, and the substrate material on electromagnetic properties of the antenna. The behaยจior of antenna electromagnetic pr

Fonnulas based on transmission-line, cauiiy, and magnetic-wall models to determine the resonant fie quencks of u rectungular microstrip antenna element haue been studied and their ualidiiy assessed. Their cariations were experimentally r;erifred by analyzing u set of newly designed untennu elements
In this article, pattern nulling techniques for linear antenna arrays that make use of phase and position perturbations based on the genetic algorithm are inยจestigated, respectiยจely. Both nulling techniques are found to be capable of steering the array nulls to the prescribed interference directions

## Abstract This letter presents the closedโfrom 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 computerโaided design (CAD) models
