A dipole antenna composed of composite right/left-handed transmission line (CRLH TL) has been proposed. The antenna is composed of lumped or distributed LC elements and interconnecting wires. The CRLH dipole antenna can be miniaturized in the fundamental resonant mode of n = −1. However, the bandwidth narrows by using CRLH TL as antenna element. In this paper, the right-handed (RH) dipole antenna with the CRLH parasitic element is presented. The proximity effect of the CRLH parasitic element has the feature of the band rejection at the resonant frequency of the original RH dipole antenna. The return loss characteristics are simulated to confirm the band rejection characteristics. The radiation patterns at the resonant and rejection frequencies are also shown. |
