Comparative Analysis of Hexagonal Stub Antenna for Wireless Applications

Abstract

This paper presents the design and analysis of a Single-layer and Multilayer Hexagonal microstrip patch antenna with the goal of enhancing bandwidth and directivity in Wireless applications. Microstrip antennas due to their small profile design take less area. Further, they can be modified by two techniques that introduce different dielectric layers by adding an Air gap between the Ground and the conducting surface to improve its Bandwidth, Gain, VSWR, Return Loss, and Directivity. In this paper, we have simulated the Single-layer and Multilayer Hexagonal Stub MSA by studying various Microstrip configurations & Mathematical designs using High-Frequency Structure Simulator (HFSS) software. The main objective of this study is to enhance the antenna's bandwidth in order to fulfill the increasing demands of modern Wireless applications. The proposed antenna enhances both bandwidth and efficiency by employing many layers. To validate the simulation results, an experimental examination was carried out with a Vector Network Analyzer (VNA). The simulated and measured results are highly consistent, indicating the suggested design's accuracy and dependability. The hexagonal multilayer patch antenna significantly enhances the bandwidth, making it suitable for a diverse variety of wireless applications. The antenna's gain, directivity, and emission pattern indicate that it is well-suited for current communication systems.
