About

The Microwave Engineering Lab provides a platform to the students which enables to learn the characteristics of Microwave components including their design. A key part of the microwave laboratory experience is to provide practical hands-on exposure on learning the use of microwave test equipment for making measurements of power, frequency, S parameters, SWR, return loss, and insertion loss. The microwave test benches and microwave kits are useful for such measurements. The Microwave Signal Generator, wave propagation trainer Kit, turn table and horn antennas are used to carry out the radiation pattern measurement experiment of different microwave antennas over L, S, C, X, Ku bands. The vector network analyzer is used to study and measure the S parameters, smith chart of different microwave components and antennas. Apart from the hardware, the student gets exposure with the cutting edge technology and research through CAD by using HFSS & CST Design Studio 3D Electromagnetic Simulator.

The Smith Chart

The Smith Chart is a fantastic tool for visualizing the impedance of a transmission line and antenna system as a function of frequency. Smith Charts can be used to increase understanding of transmission lines and how they behave from an impedance viewpoint.

Smith Charts are also extremely helpful for impedance matching, as we will see. The Smith Chart is used to display an actual (physical) antennas impedance when measured on a Vector Network Analyzer (VNA).
