DESIGN CONSIDERATIONS FOR A SIMPLE 5GHz PATCH ANTENNA

Abstract

Patch antennas have many advantages for different applications, such as their small size and compatibility with modern communication systems and devices. However, there is a lack of theoretical understanding of how the geometry of these antennas affects their performance. Previous studies have tried various shapes and sizes of the patches, ground planes and feed methods, but they often achieved good results at the cost of complexity and without clear explanations. This gap in knowledge is a common problem and needs to be addressed to improve the design and understanding of patch antennas. This article reveals the physical principles behind the optimal geometry tuning (VSWR 1.05) for a 5GHz patch antenna. It also shows how geometry tuning can enable other features, such as beam steering (Up to 25 degrees). It provides useful insights for tuning patch antennas that can help researchers and engineers in this field. Therefore, the simulation and analysis of a 5GHz antenna presented in this article is a significant contribution to the patch antenna design literature.
