Biconical Patch Antenna with Inscribed Fractal Sierpinsky Gasket for Low Range Wireless Communication Systems
Authors: , , , , ,
Abstract: In this paper, a biconical patch antenna with inscribed third iteration fractal Sierpinsky gasket is designed and optimized for operating at unlicensed ISM frequency bands. A circular split ring resonator (CSRR) is used as a defected ground-plane structure for improving antenna matching. The initial design step of the proposed antenna is based on the design methodology of multi-resonant Sierpinsky fractal patch antennas with inscribed triangular fractal geometry. Building on this, a simulation tool for high frequency electromagnetic structures is employed to optimize antenna performance. The experimental prototype is built and characterized using an antenna pattern measurement equipment and a network analyzer. Experimental results shown that the built antenna presents return losses of -23 dB, coupling bandwidth percentage of 10 %, antenna gain of 6.8 dBi, and VSWR of 1.14 at the 2.4 GHz resonant frequency. The corresponding values at the 5.9 GHz resonant frequency are -33 dB, 9 %, 8.7 dBi, and 1.043, respectively. These results show that the proposed antenna presents suitable characteristics for low range wireless communications such as WiFi (wireless LAN), Bluetooth, and ZigBee technologies.
