Printed CPW-fed dual-band antenna using square closed-ring and square split-ring resonator

This paper presents the design of dual-band antenna using metamaterial structures as radiating elements. Dual resonance is obtained by making use of square closed-ring resonator and square split-ring resonator. This research develops an antenna having dimensions of 31.7 × 27 × 1.6 mm3 which operates at two bands from 2.40 to 2.50 and from 3.41 to 4.27 GHz. This antenna can be used for WLAN and WiMAX applications at 2.45-GHz and 3.5-GHz band, respectively. This paper includes necessary parametric analyses. Comparison between numerical and actual results of an antenna is given to validate the proposed design. The proposed antenna has been fabricated and tested. Good equivalence has been found between simulated and measured results. This demonstrates the applicability of the proposed antenna.
