Abstract :
Numerical study of a high impedance surface built in microstrip technology by using periodically arranged elliptical patches, grounded through one to four vias is presented. The effect of the variation of the number of vias manifests in different manner on the electromagnetic band gap aperture and position, as results from the parametric study in function of the patch dimensions and diameters of the vias. We show that stop bands cover a frequency range with limits in a ratio of 2.48:1. The results are useful in the design of high impedance surfaces for various applications.
