Self-adhesive antennas for on-body communication
Punar, Jan ; Fiala, Pavel (referee) ; Raida, Zbyněk (advisor)
This project is focused on planar antennas for on body communication. Project follows the concept of a self-adhesive antenna, which was published in [1]. The included report contains simulation results of the designed antenna, and compares them with results given in [1]. It describes the redesign of the antenna to the operation frequency 5.8 GHz for substrate Arlon 25N followed by subsequent conversion to the thin substrate FR4. The thesis also deals with antennas not only for on body communication but also for communication between the human body and the remote unit. Finally, the work contains measurement results of the reference antenna on the Arlon 25N substrate.

Resonant switched-mode power supply with PFC
Punar, Jan ; Drda, Václav (referee) ; Záplata, Filip (advisor)
This diploma thesis is focused on the LLC resonant power supply with power factor correction. The first part of the thesis is focused on a selection of a suitable controller for the control of this source. Here the emphasis is mainly on efficiency and EMC. The thesis also deals with the design of the scheme and the selection of suitable components. The thesis contains the design of the LLC power supply itself and also the power factor correction circuit - PFC.
