Lecture

Radiation in Far Field (SIW Cavity-Backed Antenna)

Description

This lecture introduces the concept of substrate integrated waveguide (SIW) technology for cavity-backed antennas, which offer improved performance in radar and communication applications. The SIW technology enables better bandwidth, decreased radiation, and increased frequency range. The lecture covers the analysis of a SIW cavity-backed patch antenna using full-wave FEM simulation, evaluating frequency responses for different geometrical parameters.
