Abstract

In this study, a composite right-/left-handed transmission line (CRLH TL) is used as a parasitic element. It is shown that a right-handed (RH) dipole antenna with the CRLH parasitic element has band rejection characteristics. Moreover, transmission characteristics and electric field distribution confirm that mutual coupling between the two dipole antennas can be reduced by using CRLH parasitic elements between the two antennas.

由左/右复合传输线组成的寄生元件偶极子天线间的相互耦合减小
在这项研究中,一个复合的右/左手传输线(CRLH TL)被用作寄生元件。结果表明,带有CRLH寄生元件的右手偶极子天线具有带抑制特性。此外,传输特性和电场分布证实了在两根偶极子天线之间使用CRLH寄生元件可以降低两根偶极子天线之间的相互耦合。
