摘要: 為了濾除WIMAX(3.3~3.8 GHz)和WLAN(5.125~5.825 GHz)窄帶信號(hào)對(duì)超寬帶系統(tǒng)的干擾,該文提出一款共面波導(dǎo)饋電的小型化雙陷波漸變槽天線。共面波導(dǎo)結(jié)構(gòu)可以有效地?cái)U(kuò)展天線的帶寬,實(shí)現(xiàn)對(duì)整個(gè)UWB(3.1~10.6 GHz)頻段的全覆蓋。通過(guò)在天線的饋線上開(kāi)L型縫隙和在輻射貼片上開(kāi)一對(duì)E字型縫隙的方法,有效實(shí)現(xiàn)了在3.15~3.97 GHz和4.94~6.05 GHz頻段的雙陷波特性,能夠抑制WIMAX和WLAN對(duì)超寬帶系統(tǒng)的干擾。該天線結(jié)構(gòu)簡(jiǎn)單緊湊,尺寸非常小,僅為40 mm×18 mm×0.813 mm。仿真和實(shí)測(cè)結(jié)果表明該天線在超寬帶波段內(nèi)具有良好的陷波特性、增益特性,可以應(yīng)用于小型化超寬帶系統(tǒng)中。文中方法對(duì)于陷波漸變槽天線的研究具有一定的借鑒意義。Abstract: In order to filter out the interference of WIMAX (3.3~3.8 GHz) and WLAN (5.125~5.825 GHz) narrowband signals to Ultra WideBand(UWB) system, a Co-Planar Waveguide (CPW) fed miniaturized tapered slot antenna with dual band-notched characteristics is proposed. The CPW structure can effectively extend the bandwidth of the antenna and realize the full coverage of the whole UWB (3.1~10.6 GHz) frequency band. The dual band-notched characteristics (3.15~3.97 GHz and 4.94~6.05 GHz) are effectively achieved by etching the L-shaped slot in the antenna feeder and opening a pair of E-shaped slots in the radiating patch, which can inhibit WIMAX and WLAN interference to the UWB system. The antenna is simple and compact, and the size is very small, only 40 mm×18 mm×0.813 mm. The simulated and measured results show that the antenna has good notch and gain characteristics in the ultra wideband band, and can be used in miniaturized UWB system. The method has certain reference significance for the research of notched tapered slot antenna.
