High-Gain A-Shaped EBG-Backed Single-Band Planar Monopole Antenna

This paper presents the use of a backed electromagnetic band gap (EBG) structure which gives the radiation efficiently as a director for our designed monopole antenna. For the wearable applications, proposed planar monopole antenna A single EBG structure exploited towards radiation efficiently. The gap between the ground and the EBG layer, and shape of the EBG structure are fixed to work the antenna at 2.45 GHz in wireless local area network. A proposed model with unique EBG-backed monopole antenna is presented. The proposed antenna is fabricated on a 64.23 x 38 x 1.57 mm(3) board of FR4 substrate with relative permittivity of 4.4. The reported efficient and robust radiation performance with the high gain and the compact size, which make the proposed antenna to work for wearable communication applications. The detailed theoretical explanations are supported by simulations and experiments.
