| Popis: | In this paper, an UWB (ultra-wideband) fractal antenna with VSWR < 2 bandwidth of 1.2-10.8 GHz is proposed, covering the UWB spectrum (3.1-10.6 GHz). An extended C-shaped slit, a CIDCLIR (complementary interdigital capacitance loading loop resonator) and CIDCLIR with the extension line thereof are etched at the intersection of the feed line and the main radiation patch, and at the bottom and the right coplanar floor of the feeder, respectively. So that the antenna with the tripe band-notched characteristics, and the problem that the notch band is too wide to waste useful spectrum is solved, thus it has high selection filtering characteristics. Multiple notch bands are 2.4-2.6GHz, 5.05-5.8GHz, 7.83-8.44GHz, it can better filter out interference from 2.4G WLAN (Wireless Local Area Network), 5G WLAN, X-band uplink frequency, respectively. It has good radiation characteristics and certain practicability. |
