A high efficient compact CPW fed hexagonal slot antenna for diversified applications

Abstract

In this paper, a compact, high efficient CPW (co-planar waveguide) fed antenna which is used for various applications is proposed. In this work, the proposed antenna is evaluated using IE3D simulation software. The proposed antenna has the compact size of 16.55mm × 20.05mm × 1.6 mm and the substrate is RT_Duroid 5880 used (εr is 2.2 and tanδ is 0.0009). The antenna resonates at 8.5 to 8.7 GHz frequency, with a return loss value of proposed antenna shows −48dB at 8.64 GHz. The gain obtained is 5.5 dBi, VSWR of around 1.1 at 8.64 GHz. The antenna is found to have 80% efficiency.
