【摘要】：針對(duì)周期復(fù)合左/右手(Composite Right/Left-Handed,CRLH)傳輸線偶極子天線帶寬窄的問(wèn)題,提出一種非周期CRLH傳輸線的天線模型.該模型主要由N個(gè)不同尺寸的LC梯形網(wǎng)絡(luò)單元組成,實(shí)現(xiàn)參差調(diào)諧,改善天線的阻抗匹配,拓展天線帶寬.設(shè)計(jì)了一種四單元非周期CRLH偶極子天線,模擬和實(shí)驗(yàn)測(cè)試結(jié)果表明:天線的長(zhǎng)度為0.135λ_0時(shí),滿足回波損耗|S_(11)|≤-10dB的相對(duì)阻抗帶寬為8.55%,天線的匹配性能得到了改善.
[Abstract]:Aiming at the problem of narrow band width of dipole antenna of periodic composite left / right hand composite right / left left handed CRLH transmission line, an antenna model of aperiodic CRLH transmission line is proposed.The model is mainly composed of N LC trapezoidal network elements with different sizes to achieve staggered tuning improve impedance matching and expand antenna bandwidth.A four-element aperiodic CRLH dipole antenna is designed. The simulation and experimental results show that when the antenna length is 0.135 位 _ 0, the relative impedance bandwidth of 鈮，
