Abstract

This work presents the design of wideband metamaterial MTM antenna loaded with frequency reconfiguration capability. The bandwidth enhancement is based on locating best point of the horizontal slot through parametric studies within the length L3. This horizontal slot is responsible for left-handed capacitor C L to improve bandwidth. Employing CSRR generate negative permittivity which result further bandwidth enhancement at lower and upper band with better matching condition. Two Pin Diode switch reconfigured the antenna from wideband antenna to dual-band antenna. Computer Simulation Technology (CST) Software was used for simulation to determine the accuracy of the technique and it operation. Wideband with bandwidth range (2.3-5.6) GHz was obtained. This wideband is reconfigured to dual band at 2.0 GHz and 5.2 GHz were obtained. Highest peak gain obtained in H-plane are 2.75dBi and 3.24dBi at 2.4 GHz and 5.2 GHz respectively. Based on the results obtained, the antenna can be used for GSM band, lower 5G band and WLAN applications band.

基于CSRR的频率可重构宽带超材料天线设计

本文提出了一种具有频率重构能力的宽带超材料MTM天线的设计。带宽增强是基于在长度L3内通过参数研究找到水平槽的最佳点。这个水平槽负责左电容lc，以提高带宽。利用CSRR产生负介电常数，使上下带宽进一步增强，匹配条件更好。双管脚二极管开关将天线从宽带天线重新配置为双频天线。采用计算机模拟技术(CST)软件进行模拟，以确定工艺的准确性和操作方法。获得了带宽范围为(2.3-5.6)GHz的宽带。该宽带被重新配置为2.0 GHz和5.2 GHz的双频段。在2.4 GHz和5.2 GHz时，h平面的峰值增益分别为2.75dBi和3.24dBi。实验结果表明，该天线可用于GSM频段、低5G频段和WLAN应用频段。
