Abstract

In this paper, an array of 7*7 novel compact metamaterial unit cells is characterized and employed for the gain enhancement of a microstrip antenna operating at 7.1 GHz. This 7.1 GHz operating frequency is the C-band frequency which is use in the long distance for the satellite communication. The unique property of the metamaterial gathers the wave radiated from the antenna and collimates it towards the normal direction when used as a superstrate array. The proposed unit cell is obtained by suitably adding extra metal strips to the conventional mirrored S like structures. The unit cell analysis and parameter extraction using periodic boundary condition confirms the near zero index behaviour as well as significant reduction (almost 52%) in the unit cell footprint. The proposed design provides a gain enhancement of 9.4dB using a single layer superstrate, when suspended above a microstrip patch at 7.1 GHz. Simulation and measurement results confirm that Near-Zero Index Metamaterial (NZIM) lens significantly improves the gain (by more than 1.8 dBi) . A parameter-retrieval method using the S parameters is used to calculate the curves for the complex permittivity and permeability of the metamaterial based on its unit element. The S parameters are extracted using HFSSTM, which is a Finite-Element-Method (FEM)-based full-wave simulator. , Near Zero Index Metamaterials (NZIM) have the ability to control the direction of radiation.
