A high-efficiency compact split-ring resonator (SRR)–complimentary split-ring resonator (CSRR)–substrate integrated waveguide (SIW) rectangular resonator antenna based on a composite right/left-handed transmission line is presented in this paper. A four-element rectangular CSRR structure is etched on the front of the antenna, and a four-element rectangular SRR structure is loaded on the back of the metal to correspond with each other, thus forming a composite right/left-handed transmission line structure. By meandering technique, a rectangular CSRR is etched on the front of the metal surface to reduce the frequency and realize the miniaturization of the antenna. Combined with SIW rectangular resonator, the high-efficiency compact antenna is finally realized. Simulation and experimental results show that the −10 dB impedance bandwidth of the SRR–CSRR–SIW rectangular resonator antenna is 5.26∼5.29 GHz (1.14%) and 9.07∼9.15 GHz (0.88%). The resonance frequency is 5.26 and 9.11 GHz. The gains are 5.33 and 5.25 dBi. The antenna can be widely used in WLAN and WiMAX.

基于CRLH-TL的高效紧凑型SRR-CSRR-SIW天线
本文提出了一种基于复合右/左手传输线的高效紧凑型裂环谐振器(SRR)-互补裂环谐振器(CSRR)-基板集成波导(SIW)矩形谐振器天线。天线正面蚀刻四元矩形CSRR结构,金属背面加载四元矩形SRR结构相互对应,从而形成复合的左右手传输线结构. 通过曲折技术,在金属表面的正面蚀刻出矩形CSRR,以降低频率,实现天线的小型化。结合SIW矩形谐振器,最终实现了高效紧凑型天线。仿真和实验结果表明,SRR-CSRR-SIW矩形谐振器天线的-10 dB阻抗带宽为5.26∼5.29 GHz (1.14%)和9.07∼9.15 GHz (0.88%)。谐振频率为 5.26 和 9.11 GHz。增益为 5.33 和 5.25 dBi。该天线可广泛应用于WLAN和WiMAX。
