Three Unit Cell Crlh-Tl Based Zeroth Order Resonance Antenna

In this paper a Zeroth order resonance antenna based on CRLH-TL technique is proposed. To achieve a compact size antenna utilizes the ZOR phenomenon and its reactive parameters determine the resonant frequency. It consists of three top patches and the meander lines are connected to the rectangular patch. Here the meander lines acts as an inductor and the rectangular patch as a virtual ground capacitor. The proposed antenna has the benefit of compact size and easy to fabricate. The efficiency of 77% and gain of 5.445 dBi and operates at 3.1049GHz.
