| Summary: | This paper discusses the resonance of a modified bifin fractal antenna in comparison to the corresponding printed modified bifin having a centre-feed 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 structure 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. |
