Quarter-mode four-element antenna array
Janoušek, Jiří ; Fiala, Pavel (referee) ; Raida, Zbyněk (advisor)
Thesis deals with problematics of Compact Circularly Polarized Antenna Based on Quarter-Mode Substrate Integrated Waveguide Sub-Array and process. It also solves a complex structure of microstrip power distribution network. The goal was to create a~physical functioning model of this antenna and to measure its attributes in free space and also near the human body. Theoretical part of this work is taking on the calculation of parameters of the proposed antenna. Practical part is then solving modelation and simulations in program ANSYS HFSS. Physical model of the antenna was not created and some flaws were found in the presented model of the microstrip power distribution network. A possible solutions were proposed to eliminate these flaws.

Defected ground planar filters
Tomíček, Martin ; Vágner, Petr (referee) ; Raida, Zbyněk (advisor)
In the bachelor´s thesis, the microstrip low-pass filter with the defected ground is described. The project deals with the design and the simulation of the filter in Ansoft Designer, confrontation of results between simulation and realized low-pass filter and the discussion of obtained results.
