摘要: A compact and novel fractal dual band notched UWB antenna with time domain characteristics is presented. tapered microstrip fed circular radiating patch along a semi defected ground structure produce − 10 dB bandwidth from 3.73 to 16.7 GHz. The proposed miniature size of 16 × 21 mm2 printed on FR-4 substrate two high frequency bands 7.29–7.76 GHz 9.53–11.17 GHz notch X-band satellite communications link by incorporating L C-shaped parasitic elements respectively. exhibits uniform gain 2–4.26 dBi, flat group delay around 1.2 ns, peak radiation efficiency about 96% in operating frequencies makes it suitable for wireless portable devices.
