In this work, metamaterial (MTM) inspired a compact CPW-fed antenna with triple operating band is proposed. A rectangular Split Ring Resonator (SRR) is unified in a circular slot of the polygon-shaped radiator in MTM inspired antenna. The antenna exhibits three operating band which are based on metamaterial characteristics of unit cell. The CPW-fed antenna is ensuing 10 dB impedance bandwidth varies from 2.28 to 2.38 GHz, 3.07 to 3.78 GHz, and 5.05 to 7.03 GHz, whereas notch band exist from 2.39 to 3.06 GHz frequency. Metamaterial behaviour leads into the bandwidth enhancement as well as miniaturization in lower operating band with electric length of 0.14λ 0 × 0.21λ 0. The antenna archives the peak gain of 1.49 dB at 2.34 GHz, 2.04 dB at 3.32 GHz, and 4.14 dB at 6.5 GHz frequency. The measured results authenticate the simulated outcomes and consequently the proposed antenna can be pertinent in LTE, WLAN, and 5G communications.

用于 LTE/5G/WLAN 通信的 CPW 馈电超材料启发的紧凑型多频带天线

在这项工作中，超材料 (MTM) 启发了一种具有三重工作频带的紧凑型 CPW 馈电天线。矩形裂环谐振器 (SRR) 统一在 MTM 启发天线中的多边形辐射器的圆形槽中。该天线具有三个基于晶胞超材料特性的工作频带。CPW 馈电天线的 10 dB 阻抗带宽从 2.28 到 2.38 GHz、3.07 到 3.78 GHz 和 5.05 到 7.03 GHz 不等，而陷波带从 2.39 到 3.06 GHz 频率存在。超材料行为导致带宽增强以及较低工作频带的小型化，电长度为 0.14λ 0× 0.21λ 0. 该天线在 2.34 GHz 时的峰值增益为 1.49 dB，在 3.32 GHz 时为 2.04 dB，在 6.5 GHz 频率时为 4.14 dB。测量结果验证了模拟结果，因此建议的天线可适用于 LTE、WLAN 和 5G 通信。
