Abstract

In this paper, a novel simple compact electromagnetic band gap (EBG) configuration is proposed and analyzed using 3D finite difference time domain (FDTD) method. The proposed EBG structure consists of metallic square patches that arranged on ordered circular rings. The bandgap feature of surface wave suppression is demonstrated by calculating the transmission responses and near field distributions. From the investigated transmission curves, the surface wave bandgap is found to be 6.2 GHz and extends from 4.8 GHz to11 GHz. By inserting a 5.67 GHz patch antenna over the proposed 3-rings EBG structure, the -10 dB bandwidth has been enhanced by around 500% and the multiband ability is investigated. Further, the average value of the directivity over the wide frequency band has been improved by around 1.6 dB. On top of that, the design of 4-rings EBG structure is used to decrease the mutual coupling between two coupled rectangular patches with planar separation of quarter the wavelength by 5 dB. Much isolation between closely-packed antenna elements can be easily achieved by using more EBG circular rings. The proposed Microstrip antennas that utilize the proposed EBG structure are appropriate for WLAN applications
