Abstract-In this paper, the analysis and design of a compact Multiple Split Ring Resonator (MSRR) inspired microstrip rectangular patch antenna is presented. The MSRR is used with four rings. The size of the antenna is 25 × 31 × 1.6 mm 3 realized on a low cost FR4 substrate. The proposed rectangular microstrip patch antenna operates at the resonant frequency of 5.88 GHz prior to MSRR inclusion. The antenna characteristics are studied before and after inclusion of metamaterial. After including MSRRs at appropriate places, the proposed MSRR antenna induces a new resonant frequency of 2.78 GHz. In addition to rectangular patch's fundamental resonance, the additional resonance is obtained at 2.78 GHz, thus, exhibits dual bands. Hence, MSRR loading antenna attains a bandwidth of 197 MHz at 2.78 GHz and 703 MHz at 5.88 GHz. The prototype of the proposed antenna is fabricated and measured. Simulated results are verified with the measured ones. This proposed antenna can be effectively utilized for WLAN and RF-ID applications. Parametric studies are illustrated to yield the desired frequency bands. Equivalent circuit model analysis of the MSRR loading is determined. Band characteristics of split ring structure are used to determine the negative permeability characteristics.

Abstract-In present scenario, this paper intends to demonstrate the practicality of a miniaturized coplanar waveguide fed metamaterial inspired antenna that can be effectively operated at dual bands. A broad-side coupled Split Ring Resonator is used to obtain dual bands with an impedance bandwidth (−10 dB) of 840 MHz (3.00-3.84 GHz) and 310 MHz (5.94-6.25 GHz), which resonates at dual bands, viz., 3.42 GHz and 6.07 GHz. The impedance bandwidth (S 11 < −10 dB) is 25% for the first band and 5.1% for the second band. The size of the antenna is 31×25×1.6 mm 3 realized on a low-cost FR-4 Epoxy substrate. This antenna can be effectively utilized in worldwide interoperability for microwave access (WiMAX) and wireless access in vehicular environments (WAVE) applications. The prototype of the proposed antenna is fabricated and measured. Simulated and measured results are in agreeing nature. Experimental and simulated analyses of the antenna including parametric and dispersion characteristics are dealt in this communication.
