An EBG microstrip antenna for 5.4 GHz WLAN/HIPERLAN applications

This study proposed a compact microstrip antenna for 5.4 GHz WLAN/HIPERLAN applications, which achieved a bandwidth of 230 MHz and peak gain of 3.6 dB at 5.4 GHz. The antenna is incorporated with a new electromagnetic bandgap structure that is comprised of a 3×3 array of N-like shape unit. The EBG antenna gives wider bandwidth of 320 MHz, better return loss and improved gain up to 5.46 dB. Enhancement of antenna performances proves the effectiveness of the proposed EBG structure. The design is simulated and analyzed with finite element method based solver HFSS.
