RECONFIGURABLE OCTAGON SPLIT RING RESONATOR MICROSTRIP PATCH ANTENNA

Abstract

This paper presents the design and analysis of a reconfigurable octagon split ring resonator microstrip patch antenna. The objective of this work is to fulfill the demand for multiband applications in modern wireless communication systems. The antenna structure consists of an octagon-shaped split ring resonator integrated as a microstrip patch, with a patch dimension of 11.6×11.6 mm². By strategically tuning the geometric and feed location, the antenna is capable of operating at two distinct frequency bands within the range of 2.4 GHz and 5.2 GHz, facilitating frequencies reconfiguration within a single antenna unit. Design parameters such as Voltage Standing Wave Ratio (VSWR), return loss (S11), bandwidth, and gain are investigated using High Frequency Structure Simulator (HFSS). The proposed antenna offers considerable gain and bandwidth suitable for multiband wireless applications.
