DESIGN AND ANALYSIS OF HETERO TRIANGLE LINKED HYBRID WEB FRACTAL ANTENNA FOR WIDE BAND APPLICATIONS

Design and analysis of a novel wide-band covering, hetero triangle linked hybrid web fractal antenna is presented in this paper. The hetero triangle linked hybrid web structure has been designed through multiple iterations in the CST MICROWAVE STUDIO electromagnetic simulation tool and has been fabricated on FR4 dielectric of εr = 4.4 with height of 1.6 mm. The proposed antenna offers a comprehensive bandwidth of 18.055 GHz, covering from 1.945 GHz to 20 GHz. It supports various applications starting from 3G, LTE, ISM, Bluetooth, Wi-Fi, WLAN (2.4–2.48 GHz) and 5.2/5.8 GHz (5.15–5.35 GHz/5.72–5.82 GHz), WiMAX operating in the 2.3/2.5 GHz (2.305–2.36 GHz/2.5–2.69 GHz), 5.5 GHz (5.25–5.85 GHz) and Satellite communication (Ku band: Uplink of 14 GHz and Downlink of 10.9–12.75 GHz). The proposed antenna provides peak realized gain of 7.17 dB with efficiency more than 78% in the operating band. The antenna parameters such as reflection coefficient, gain and radiation patterns are determined through numerical simulation, and good matching is obtained with measured results.
