Miniaturized Antenna for IOT Application

Abstract

Ansys platform-based HFSS simulator software is used to create a 4GHz circular micro strip patch antenna array. Applications including Bluetooth, the Internet of Things, and several WLANs can all benefit from it. The circular patch antenna, which is constructed on a FR4 substrate with a dielectric constant of 4.4 and a height of 1.6mm, is fed using edge feeding. The antenna is built using a 1.4mm thick FR-4 (lossy) substrate with a relative permittivity of 4.4 and a microstrip line feed. The chosen radius for the circular patch is 7.62mm. To lower the size and enhance the performance of the suggested antenna, a square slit 30mm by 30mm in size is etched onto the ground plane. The HFSS Simulation Program is employed in the antenna's design. Antenna characteristics such as return loss, radiation pattern, bandwidth, orientation, antenna gain and radiated efficiency are all studied.
