Planar Microwave Techniques

Lecturer:

Karel Hoffmann (gar.)

Tutor:

Karel Hoffmann (gar.), Přemysl Hudec

Supervisor:

Department of Electromagnetic Field

Synopsis:

Project oriented subject covers problems of passive planar circuits applied in frequency bands of microwaves and mm waves. CAD tools. Strip, microstrip, slot and coplanar lines. Coupled lines. Directional couplers. Power dividers. Lumped parameter elements. Planar filters and resonant circuits. During seminars and laboratories students use professional software CAD tools and design these circuit in diferent structures.
