Abstract

This paper presents a metamaterial loaded interdigital capacitor antenna having fractal geometry. The antenna consists of multiple split ring resonators (MSRR) with shorted ground. The metamaterial loading is achieved by MSRR that enhances the gain. Furthermore, multiband characteristics is obtained by two L-shaped rings providing the fractal geometry. The antenna has the physical dimension of 27 × 39.20 mm for the outer ring and in terms of wavelength has the dimension of 0.486 × 0.707λ. This antenna structure is designed and simulated on an FR-4 epoxy substrate of thickness h = 1.56 mm and dielectric constant εr = 4.4. The antenna resonates at multiple frequencies i.e. 1.5 GHz, 2.2 GHz, 2.70 GHz, 4.20 GHz, 4.9 GHz, 5.3 GHz, 7.2 GHz, 7.5 GHz and 8.8 GHz respectively at different matching values with gains of 9.5 dB, 14.5 dB, 11.9 dB, 3.6 dB, 4 dB, 1.5 dB, 3.8 dB and 6.5 dB. The comparison of the simulated and measured return losses shows a good agreement. The antenna finds its applications in GPS, space and satellite communication, radar, body area network (BAN) communication system.
