CB-CPW fed compact antenna for WLAN applications

Abstract

In this paper, a novel conductor backed coplanar waveguide (CB-CPW) compact antenna for wireless local area network (WLAN) applications is proposed. CB-CPW is different from conventional CPW in a sense that it has an additional ground at the bottom surface of the substrate material. This bottom ground plane not only offers mechanical support to the substrate but also works as a heat sink for circuits with active devices. The antenna is designed on a flame retardant woven glass reinforced epoxy resin (FR4) substrate material. The proposed design has reduced total area by 55 percentage with respect to the previous similar antenna. The antenna parameters such as 2D radiation patterns, gain, VSWR, return loss, and antenna efficiency are obtained and all of them meet acceptable standards of basic antenna. Numerical simulations are carried out using IE3D software based on Method of Moment (MoM) technique.
