Abstract

In this paper, for industrial, scientific, medical (ISM) band applications, a new multilayer stacked substrates H-shaped patch antenna with microstrip feedline is proposed. The designed structure has stacked FR-4 substrates with embedded ground plane. In order to accomplish the ISM (2.4 GHz), the configured H-shaped patch antenna with an opening slot on ground and the novel H-shaped patch antenna imposed over a second layer. Also, there are several specifications that have to be altered for optimum bandwidth characteristics, including the width and length of each patch, substrate thickness, and feed point position. The results demonstrate that return loss is −26.6 dB and VSWR 1.09 at 2.4 GHz. The enacted antenna has adequate bandwidth at the specified band and signifies 2.27–2.4 GHz transmission capacity. An intended multilayer antenna has 5.6 dBi gain at 2.4 GHz. The optimized structure is easy to acquire, has less volume, compact size, and adequate bandwidth of deployment. For ISM band applications, the configured multilayer patch antenna is appropriate. Here, the results revealed that it is indeed a great long—effective range antenna performance for WLAN correspondence on the working band in exercise. The radiation designs are comparable and the gain can satisfy the need for the correspondence applications over the working recurrence band. Reenactment is finished by utilizing computer simulation technology (CST).
