Course detail

Simulation of Communication Subsystems

FEKT-BPC-SKSAcad. year: 2020/2021

Students become familiar with principles of passive and active microwave circuits simulation using software Ansoft HFSS and Designer. Students use theoretical knowledge from previous courses (antennas filters, amplifiers ...) for computer aided design. Students will learn principles of selected numerical methods and methods of local and global optimization. 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 and choose appropriate method for selected problem, formulate the fitness functon


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

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 30 points for the activity in the computer labs. Two tests during the semester are honored by max. 30 points and final individual project is honored by max. 40 points.
