Abstract
A wideband Minkowski fractal antenna with complimentary quadruple P-spiral split ring resonator (QPS-SRR) is proposed in this paper. Four minis complimentary QPS-SRR structure had been connected to the corner of the main Minkowski Island fractal to investigate the effect to the resonant frequency, return loss, bandwidth and gain of the antenna. Firstly a basic Minkowski Island of Design A is simulating. Then 2-N of complimentary QPS-SRR (Design B1 and Design B2) is added to the antenna. Lastly, five different sizes of complimentary 4-N QPS-SRR (Design C1, Design C2, Design C3, Design C4 and Design C5) is added in the antenna to compared its effect. Design C is effect to resonate at two different frequencies of 2.28 GHz and 3.336 GHz with return loss of – 13.252 dB and – 19.296 dB. This antenna also can be applies at 2.4 GHz of WLAN application and 3.5 GHz WiMAX application with return loss performance of – 13.252 dB and -12.26 dB, respectively. It shows the single bandwidth of the 4.8 mm width x 4.8 mm length QPS-SRR (Design C3) is 1.218 GHz.
