Use of High-Impedance Screens for Enhancing Antenna Performance with Electromagnetic Compatibility

When developing a wireless communication system, a designer should consider the associated radiated power density, Electro-Magnetic Compatibility (EMC) and Specific Absorption Rate (SAR). In this paper, High-Impedance Surface (HIS) are designed as an EM protection screen to reduce the interaction between an antenna and the user behind the screen. The effects of an HIS screen with a finite number of cells placed near a monopole antenna for the application of the 2.4GHz WLAN band were thoroughly investigated.
