Planar monopole antenna with compact EBG for wireless body area network (WBAN) applications

Abstract

The letter presents a planar antenna backed with an EBG structure. The properties of the EBG have been studied and obtained efficient radiation of an antenna which is used for wearable applications. The gap that separates the ground and the EBG layer is varied due to which the antenna radiates at 2.48 GHz. The prototype models of antenna show measured gain of 6.5 dBi with the EBG structure on the background. The proposed prototype is fabricated on a 30 x 20 x 0.7 mm3 denim substrate has dielectric constant of 1.7mm as its property. Detailed analysis of the prototype and results exhibited for various cases are shown, and in all conditions the antenna withholds its performance. The efficient radiation patterns, high gain and compact size makes the proposed antenna a worthy choice for wireless body area network communication.
