Abstract

In this study, a dual-band high-impedance surface (HIS) structure and a dual-band monopole antenna were designed for 2.45 GHz and 5.25 GHz WLAN applications. This HIS structure was proposed as an electromagnetic (EM) protective sheet to reduce undesirable EM radiation of antenna. The effects of EM protection sheets including metallic plates, R-cards, and HIS on the specific absorption rate (SAR) and on the antenna performance were then numerically and experimentally investigated. It was found that that the HIS can serve as an EM protective sheet without affecting the forward radiation power of the antenna.
