Experimental tags for UHF RFID applications
Pacholík, Vladimír ; Holek, Karel (referee) ; Lukeš, Zbyněk (advisor)
This thesis deals with RFID tags design. It comprises an overview of the RDIF technology while focusing upon the passive tags in UHF band. The CST Microwave studio software has been used for draft simulations. The resulting tags have been subjected to parameter measuring – the reflection coefficient, the minimum capacity needed to switch on the tag, the maximum reading distance. The influence of the proximity of metal objects and other materials has also been examined.

Dual-port microstrip circularly-polarised antenna
Holek, Karel ; Horák, Jiří (referee) ; Lukeš, Zbyněk (advisor)
The thesis is focused at the design and the execution of a dual-port microstrip circularly-polarized antenna for the frequency of 2.4 GHz. The first part describes general knowledge about microstrip antennas, circularly-polarized, options of power supply, used medium etc. The second part of the thesis deals with the design and simulation of antennas with the use of software called CST Microwave Studio and Zeland IE3D. In the last part, confrontation of simulation and measurement results is provided.
