Course detail

Microwave Techniques

FEKT-BKC-MVTAcad. year: 2023/2024

The subject introduces circuit techniques in the frequency range up to tens of GHz. The lectures are concentrated on the presentation of basic principles and properties of microwave structures whose knowledge is necessary for the design of devices not only for communication purposes. Laboratory exercises practically familiarize students with individual microwave circuits and measurement methods.

Number of ECTS credits


Mode of study

Not applicable.

Entry knowledge

Students who enroll the course should be able to:
- compute with complex numbers;
- explain fundamental principles of theory of electromagnetic waves and transmission lines(Maxwell’s equations, propagation of a wave along transmission line, transmission line parameters);
- work with Smith chart.

The work in the laboratory is conditioned by a valid qualification of a "instructed worker" according to 50/1978 Coll., which students must obtain before the start of classes. Information on this qualification is given in the Dean's Directive Familiarization of students with safety regulations. 


Rules for evaluation and completion of the course

A test written during semester (15 points), laboratory exercises (20 points), written final exam (65 points). 


Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course annually.


The subject is aimed to present basic principles of microwave techniques in the frequency range up to tens of GHz, and on practicing practical approaches to computing parameters of basic transmission structures and microwave circuits.
The graduate is able to:
- describe, analyze and design a coax line, and metal rectangular and circular waveguides;
- explain „hybrid microwave integrated circuit“;
- describe basic types of passive microwave integrated structures ( microstrip, coplanar, slot one) and compare them;
- explain „monolithic microwave integrated circuit“;
- describe basic types of microwave resonators (transmission lines resonators, cavity resonators, planar resonators, dielectric resonators);
- explain coupling of cavity resonators to surrounding circuits;
- explain basic principles of a waveguide and cavity resonator excitation;
- analyze and design transmission lines and cavity resonators;
- explain „power divider“ and a principle of Wilkinson power divider;
- explain „directional coupler“, define its basic parameters and explain „quadrature hybrid“;
- explain principles on which waveguide microwave attenuators, phase shifters, and reactance components are based;
- explain „ferrite isolator“ and „ferrite circulator“, explain principles on which they are based and specify areas of their application;
- explain „substrate integrated waveguide“, specify its basic properties and compare it with a rectangular waveguide.
