Course detail

CAD in Communication Subsystems

FEKT-BRKSAcad. year: 2018/2019

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.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods include lectures and computer laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to elaborate a single project/assignment during the course.

Assesment methods and criteria linked to learning outcomes

Students can obtain up to 40 points for the activity in the computer labs. Two tests during the semester are honored by max. 24 points and final individual project is honored by max. 36 points.
