Circular Array Antenna for Super Wide Band Operation

Abstract

This work describes the design and analysis of a 22 circular micro-strip patch antenna array on a FR-4 epoxy substrate. The thickness of the substrate is 1.6 mm, and it is used in a variety of applications, including RADAR and radio frequency identification. The task involves creating a 22 circular microstrip patch antenna array that resonates at 2.4GHz and simulating it for use in Wireless Sensor Network (WSN) applications. An FR-4 Epoxy substrate is used to create a circular patch antenna array, which is then supplied using microstrip feed lines. A manufactured antenna has a 1.187GHz resonance. The analysis of antenna parameters includes gain, return loss, VSWR, directivity, reflection coefficient, and radiation pattern. In comparison to a 2x2 rectangular microstrip patch antenna, a 2x2 circular microstrip patch antenna generates better gain and less return loss. It is more helpful for WSN applications than a rectangular array due to its small size and improved directivity.
