University
Learning Outcomes
- Aware of parameter considerations viz. antenna efficiency, beam efficiency, radiation resistance, etc. in the design of an antenna.
- Capable of analyzing the designed antenna and field evaluation under various conditions and formulate the electric as well as the magnetic fields equation set for far-field and near field conditions.
- Understand the Array system of different antennas and field analysis under application of different currents to the individual antenna elements.
- Understand the design issues, operation of fundamental antennas like Yagi-Uda, Horn antennas, and helical structure, and also their operation methodology in practice.
- Design a lens structure and also the bench step for antenna parameter measurement of testing for their effectiveness.
- Knowledge about the means of propagation of Electromagnetic waves i.e. free space propagation and also about frequency-dependent layer selection, its respective issues for effective transmission of information in the form of EM waves to a remote location, and related issues.
