Modelling of Hexagonal Electromagnetic Sensor

Abstract

This paper introduces hexagonal shape sensors that is a meander and mesh type. Modelling, simulation and development of Hexagonal Sensor and the results are discussed in this paper. The characteristics of hexagonal spiral inductor and interdigital capacitor are determined. The hexagonal spiral inductor is a new electronic sensor that can be used for various measurements that produces magnetic field. The interdigital capacitor has been designed with two different widths of electrode results in electric field generation. This hexagonal spiral inductor and interdigital sensor are combined to form one single hexagonal electromagnetic sensor, interdigital sensor at the centre of the spiral. The developed structure is double sided with hexagonal spiral inductor and interdigital sensor on top and ground on the other side. The sensor is designed using COMSOL Multiphysics software to calculate sensors' characteristics and it has been fabricated on FR4 substrate of thickness 0.8mm.
