【摘要】：針對周期復合左/右手(Composite Right/Left-Handed,CRLH)傳輸線偶極子天線帶寬窄的問題,提出一種非周期CRLH傳輸線的天線模型.該模型主要由N個不同尺寸的LC梯形網絡單元組成,實現參差調諧,改善天線的阻抗匹配,拓展天線帶寬.設計了一種四單元非周期CRLH偶極子天線,模擬和實驗測試結果表明:天線的長度為0.135λ_0時,滿足回波損耗|S_(11)|≤-10dB的相對阻抗帶寬為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，
