Course detail

CAD in Communication Subsystems

FEKT-CRKSAcad. year: 2019/2020

Students become familiar with principles of passive and active microwave circuits simulation using software Ansoft HFSS and Designer. The Ansoft HFSS is an EM simulator intended for solving arbitrary 3D passive structures. Ansoft Designer is intended for circuit models and planar structures including active components. The course is terminated by an individual project, where students design a model of selected microwave circuit.

Learning outcomes of the course unit

The graduate is able to:
- understand principles of waveguides, coaxial and microstrip transmission lines, waveguide and planar antennas, power splitters, filters, microwave amplifiers
- design these structures using a simulation software
- understand principles of selected optimization techniques

Prerequisites

Knowledge of bachelor-degree mathematics and physics is required. Previous passing courses High frequency techniques and Microwave techniques is an advantage.
