Design of Rectangular shape Meta-Material Antenna for C band applications

The demand for Wireless technologies has been increasing in recent years which enabled research on antenna design. Microstrip patch antennas were preferred in modern wireless devices because of its low profile design with compact size. The major limitation of the patch antenna is its low bandwidth. The parameters of the antenna can be altered to a larger extent by adding Meta material to the substrate. This paper presents the design of rectangular-shaped Meta material antenna using Computer Simulation Technology (CST) studio suite. This paper compares the design of the antenna with and without Meta material in the substrate. At first, various designs of antennas were simulated without adding Meta material in the substrate by optimizing the shapes and the parameters such as return loss, gain, directivity etc were noted. The spanner and rectangular shaped antenna were selected based on the simulation and Meta material was added to the substrate. The rectangular-shaped patch antenna shows enhanced results than the spanner shaped antenna after adding the Meta material to the substrate. The return loss of rectangular patch antenna with Meta material was observed as -27.38 using the simulation. This range of return loss is best suited for RF energy harvesting and bio-medical applications in the C band.
