Patch Antenna Gain Improvement with Metamaterial Structures

This work presents an approach for improving both the gain and the matching of a circular patch antenna using metamaterials (MTMs). It shows that with appropriate MTMs layers, a gain increase of +1.759 dB and an optimization band of 800 MHz can be achieved. In this simulation-based study, the proposed design has been realized using CST Microwave Studio. The solution proposed here is planar, simple to manufacture and has multiple applications.
