Design of miniaturized fractal quasi-self complimentary antenna for UWB applications

A novel microstrip-fed quasi self-complementary fractal antenna is designed and fabricated to achieve the desired Ultra Wideband (UWB) features. The prospective antenna has a total size of 15 × 13 × 1.5 mm3 that empowers planting in different portable devices. A wide impedance bandwidth is achieved covering the band from 3.6 GHz to more than 14 GHz with reflection coefficient superior to - 10dB. Omnidirectional radiation pattern with stable radiation characteristics is acquired. Good agreement is achieved between simulated and measurement results as a proof of concept.
