Abstract

In this paper, metamaterial approaches are used to improve the gain, bandwidth, and radiation efficiency of microstrip patch antennas for 60GHz applications. In order to lower surface wave losses and improve the performance of proposed antennas, this work investigates a variety of techniques, including the use of metamaterials as antenna lens and as electromagnetic bandgap (EBG) structures.
To overcome the narrow bandwidth (2 GHz) and low gain (1.9 dB) of a conventional GaAs-based microstrip patch antenna operating at 60GHz, several enhancements were investigated via HFSS simulations, the result were cross validated and compared using CST Microwave Studio. Integrating an Electromagnetic Band-Gap (EBG) structure improved performance to a 7.3GHz bandwidth and 3.5dB gain. The most substantial enhancement was realized by combining the EBG with a lens technique, achieving a 10GHz bandwidth and 4.8dB gain. These results confirm that metamaterial-inspired techniques are highly effective for advancing high-frequency antennas, particularly for 60GHz communication systems.
