具有三陷波特性的超宽带天线设计
Design of ultra-wideband antenna with triple band-notched characteristics
摘要
Abstract
A compact coplanar-waveguide-fed ultra-wideband antenna with triple band-notched characteristics is designed. The antenna uses rectangle patches as a radiation unit. By etching nested inverted U-shaped, circular arc shaped and S-shaped slots, band-notched function is achieved in the three subbands of 3. 3-3. 7 GHz for worldwide interoperability for microwave access (WiMAX) , 5. 150-5. 825 GHz for wireless local area networks(WLAN) and 7. 25-7. 75 GHz for the downlink of X-band satellite communication systems. The result shows that the voltage standing wave ratio(VSWR) of the antenna in the band of 3. 1-12. 0 GHz is less than 2. The proposed antenna has a stable gain and almost omnidirectional radiation patterns.关键词
