Abstract

The main motive of the miniaturized sensing antennas is low profile, compact square antennas to operate in K and Ka band applications. Since Substrate integrated waveguide (SIW) technology exhibits low copper loss, reduced surface waves and low dielectric loss property it is involved in the design. In this paper, a square waveguide resonator is proposed to covers frequency range of 20 to 45 GHz and the electrical parameters of the antenna like return loss, gain, radiation pattern, and VSWR are investigated. The square resonator has conducting cylinders know as via-holes along the sides of the patch which makes it a good electrical conductor (EC) and from other side a good magnetic conductor (MC). The proposed square resonators contribute to the design of compact structure. The structure of HMSIW has Triple band which has maximum return loss of -20.5 dB at 36.75 GHz whereas FMSIW square shaped antenna has Hepta band maximum return loss of -21.5 dB at 40.5 GHz..

Highlights

Substrate integrated waveguide is the technology used for sensing antennas
The stimulation of Square resonator is done by ANSYS HFSS v19 from which stimulated results are obtained and compared for Full-mode and Half-mode structures
The power of the returned signal or a discontinuity which is reflected in a transmission line is called Return loss

Summary

Introduction

In the era of modern science, communication plays a vital role in today’s world and at the same time it must be a low band application. It helps people to communicate all over the world through many devices such as mobile phones, laptops etc., Antenna is an important tool in communication engineering. The frequency ranging from 3 KHz to 300 GHz are used for communications or radar signals. It is mainly used in satellite communication and radars. The 5th generation mobile networks are based on the K and Ka band frequency ranging from 18 – 40 GHZ. Substrate integrated waveguide is the technology used for sensing antennas. This global urging technology is used worldwide in different domains
