Wideband frequency reconfigurable metamaterial antenna employing SRR and CSRR for WLAN application

Abstract

This paper presents the design of Wideband Frequency Reconfigurable Metamaterial Antenna by Employing Split Ring Resonator (SRR) and Complementary Split Ring Resonator (CSRR) for Wireles Area Network (WLAN) Apllication. The design is based on reconfiguring wideband metamaterial antenna by applying frequency reconfiguration technique. This was achieved by employing SRR and CSRR for bandwidth enhacement and two PIN Diode switches at different position for reconfiguration. The antenna has electrical dimention of at 2.4 GHz. Computer Simulation Technology (CST) Software was used to determine the effectiveness of the technique. This design has several advantages like wider bandwidth which cover 2.4 GHz and 5.2 GHz WLAN bands, with three different single bands. From the simulation results, it was found that, the antenna has a bandwidth which covered 2.4 to 5.6 GHz, single bands at 2.5 GHz, 3.0 GHz and 3.5 GHz, with realized peak gain of 2.24 dBi and 3.9 dBi at 2.4 GHz and 5.2 GHz respectively and average efficiency of 96%. The antenna can be used for wireless application and cognitive radio application.

Wideband frequency reconfigurable metamaterial antenna design with double H slots

“…Also [17] achieved compound reconfiguration with dual frequency band. Multi band antennas were obtained in [18][19][20][21][22]. From the overview, up to now, there is limited bandwidth of operation from the latest work done in [12,13,23,24].…”

A new double ш-shaped compact negative refractive index metamaterial for wideband applications

“…Bashar et al proposed a dual band modified split square resonator metamateraial structure [21]. Adamu et al designed a metamaterial antenna employing SSR and CSRR for WLAN application [22]. Hossain et al designed a "combination of double Tand double U-shaped split ring resonators with square split ring resonator" metamaterial in the microwave range, whereas the size of the published design structure was 10.5 × 12 × 1.6 mm 3 that was large compared to proposed design structure [23].…”
