A Novel Proposal of Artificial Magnetic Conductor Loaded Rectangular Patch Antenna for Wireless Applications

摘要

This paper presents a novel design of a rectangular patch antenna loaded with artificial magnetic conductor designed for WLAN applications. The proposed Artificial Magnetic Conductor (AMC) lends provision for operating at both the popular ISM bands. However, here the antenna is designed to operate at 6 GHz with a bandwidth of around 160 MHz which is suitable for the intended applications. The antenna has been analyzed for its performance in terms of return loss and VSWR. The performance of antenna loaded with the AMC is observed to possess better properties in comparison to the one without AMC. AMC loaded antenna shows 90.79 % improvement in VSWR at 6 GHz compared to its counterpart. For better comparison, their respective directivities, gains and 3D polar plots have been obtained and presented.
