An electrical model to design a Metamaterial Left Hand Antenna

Abstract

This paper proposes a novel approach to study the Left hand antenna using an adequate electrical model. The structure is composed by a periodic Split Ring Resonator and a metallic wires, that’s why the proposed model take into consideration the model of each element and the coupling between the element. Due to the complexity of the structure, the model becomes very important because it’s simple, accurate and a very fast. Besides, once the model is built, it will be easy to control the structure with any change in the structure, the excitation, the substrate. The proposed antenna was manufactured on a FR-4 epoxy. The antenna is designed to RFID application, exactly for an RFID Reader. The antenna presents a significant gain superior to 16dB, and it is designed to simulate at 2.45 GHz.
