Fractal microstrip antenna with Minkowski Island split ring resonator for broadband application

A fractal microstrip antenna with Minkowski Island split ring resonator (MI-SRR) is proposed in this paper. Four minis MI-SRR structure had been connected to the corner of the main Minkowski Island Fractal to improve the bandwidth of the antenna. This antenna radiates at the broadband range from 2.09 GHz to 3.64 GHz with a bandwidth of 1.55 GHz. The first resonant frequencies for this antenna are at 2.292 GHz with - 14.515 dB of return loss while the second resonant frequency is at 3.428 GHz with - 28.585 dB. Design A and Design B have compared its return loss, resonant frequency, gain and bandwidth performance with the previous Minkowski Island antenna. The simulation work in CST Microwave Studio simulation software also had been compared with the measured fractal microstrip antenna.
