摘要：
An ultra-wideband fractal antenna is proposed, which has an isosceles trapezoid ground-plane. Increasing fractal iterations and optimizing ground-plane shape can achieve a better impedance matching so as to realize Ultra-WideBand (UWB) antenna performance. The presented fractal antenna offers a -10 dB return loss bandwidth in the range of 4.2 to 17.5 GHz (relative band is 122.6%) with electrical dimension of 0.35λ× 0.35λ. Thus, this type of antenna is suitable for C, X, Ku and UWB band communications, which may have a wide application prospect. The measured results fit well with the simulation results, and the effectiveness is validated using the measured results. ©, 2015, Science Press. All right reserved.
