Substrate Integrated Waveguide Based Leaky Wave Antenna for High Frequency Applications and IoT

Abstract

Background & Objective: Internet of things devices managed by wireless networks so that higher data rates can be achieved. With increase in demand of usage of Internet microwave signals are capable for delivering the demand. However these high frequency waves needs a waveguide to propagate otherwise they get affected due to atmospheric attenuation and rain fade. A modified structure of rectangular waveguide is used named as Substrate Integrated Waveguide (SIW). Methods: In this paper, the work has been carried out taking SIW and Leaky Wave Antenna. The dielectric substrate was taken as carbon. Modeling of SIW Leaky wave Antenna is done by making C shaped Slots. Design steps for modeling LWA were orderly pursued also optimized with various equations followed by Finite Element Method based modeling. A range of frequency as input is taken from 7 GHz to 11 GHz to take the analysis of design modeled. Results: The result shows the electric field intensity and radiation pattern is directly proportional with frequency while the return loss is acceptable for applied frequency range. Conclusion: The proposed antenna can radiate in omni directional radiation pattern hence can be used to connect devices with IoT.
