Abstract

Fractal and reconfigurable antennas are the need of modern wireless communication systems that operate under dynamic scenarios catering to the diversified needs of modern wireless applications. In this dissemination, a novel multiband Fractal Reconfigurable Antenna (FRA) has been presented and discussed using two RF PIN diodes as switching elements for electronic reconfiguration. It is analyzed using equivalent circuit concept and investigated in terms of various antenna performance parameters. The proposed FRA can operate in various frequency bands resonating at four different frequencies with switchable bandwidth and gain. The highest gain is observed to be about 8.37 dB at 9.68 GHz while the highest bandwidth is about 540 MHz in the X-band. The simulation and measurement results obtained are found to be in agreement. The multiband characteristics of the proposed FRA make it useful for smart wireless communication applications in the S (2-4 GHz), C (4-8 GHz) and X (8-12 GHz) microwave bands.
