Frequency Reconfigurable Wideband Metamaterial Antenna Design with CSRR

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.
