频带展宽的复合左右手传输线偶极子天线
Bandwidth-extended dipole antenna based on composite right/left handed transmission line
摘要
Abstract
To solve the problem of narrow bandwidth in electrically small antenna which employs pe-riodic composite right/left-handed(CRLH)transmission line,a new type of electrically small dipole anten-na using non-periodic CRLH transmission line is proposed.The model includes N units of various size LC ladder network cells.Staggered tuning is implemented to improve the antenna impedance matching and broaden the antenna bandwidth.A four units non-periodic CRLH dipole antenna is designed.The simula-tion and experiment show that when the length of the antenna is 0.135λ0 ,8.55% impedance bandwidth with |S1 1|≤-10 dB can be achieved.The matching performance of the antenna is improved to a large ex-tent.关键词
