Modified bifin fractal antenna with size reduction

Abstract

This paper discusses the resonance of a modified bifin fractal antenna in comparison to the corresponding printed modified bifin having a centrefeed microstrip line. The antennas are designed based on a finite biconical antenna operating at 1.575 GHz.The Global Positioning Satellite system receiver operates at this frequency. Modifications have been made to the bifin struclure which is half-wavelength long. The modification done on the bifin is intended to maintain the operating frequency. Hence, a compact structure can be obtained. By employing a configuration that resembles the fractal, the modified antenna is further reduced in size. The modified bifin antennas have 60' arm flare angle. The antennas have been successfully investigated using numerical simulations. The one-port performance of each modified fractal bifin is investigated and analysed. The structures operate at the corresponding frequency of operations.
