Abstract
This article presents the Pin Wheel Fractal Antenna (PWFA) loaded with Split Ring Resonator (SRR) for X-band and Ku-band wireless applications. The performance of the final iteration of the proposed PWFA has been improved with the loading of SRR in terms of reflection coefficient, bandwidth and gain. The proposed design is fed with 50 Ω microstrip line along with the quarter-wave impedance matching line. To obtain the resonance and radiation characteristics, ground plane length and width of matching line has also been optimized. The bandwidth and gain improved by 26.6% and 31.3% respectively in the first resonance (C-band) and by 16.5% and 8.1% respectively in second resonance (Ku-band) in SRR loaded structure. A prototype of the proposed PWFA is also fabricated and comparison of the simulated and measured results are found in good agreement. The overall dimension of the proposed design is 30 mm × 30 mm, which can be used for various commercial, military and mobile communication systems for C-band and Ku-band.
