Paper Title:A Compact Microstrip-Fed Patch Antenna with Enhanced Bandwidth for Wi-Fi/Wi-Max Applications using Metamaterial


A microstrip fed patch antenna with features of bandwidth enhancement is proposed. For this purpose a pair of λ/4 resonators was introduced with insert fed technique to a rectangular patch. The wide bandwidth property can be obtained by using the radiating patch and non- radiating λ/4 resonators. Substrate used for this purpose is FR-4 EPOXY with an operating frequency of 4.8 GHz which reduces the cost of the designed antenna and hence results in the increased bandwidth. The bandwidth thus obtained is twice the bandwidth of the traditional microstrip patch thus resulting in higher range for Wi-Fi/Wi-Max applications.
