Design of Notch Ultra-Wideband Antenna with New Oval CRSS Structure
摘要：The paper has achieved a more efficient narrowband filter for multi-notch ultra-wideband antenna in the case of international spectrum resource constraints. The paper is improving to the original design multi-notch ultra-wideband antenna.The way of coplanar-waveguide（CPW） coupled-fed have achieved band widening. The antenna has a large bandwidth covering the frequency band from 2.4 GHz15.1 GHz with return loss larger than 10 d B. There is the improved elliptical CSRR（complementary split-ring resonator） structure on the radiation patch of a wine glass shaped ultra-wideband antenna, which have achieved notch features ultra-wideband antenna. The new antenna has finished band rejection in WLAN uplink and downlink frequency bands, and exhibited excellent filtering characteristic. Multi-notch is implemented in 5.06 GHz to 5.46 GHZ, 5.72 GHz 6.22 GHZ. at the same time avoiding interference the part of the C-band satellite communications downlink frequency band in 5.9 GHz 6.425 GHz.The design of multi-notch ultra-wideband antenna has a good omni-directional radiation in their workspace.
