Design of dualband antenna for WiFi USB Dongle
Prchal, Lukáš ; Tkadlec, Roman (referee) ; Wolanský, David (advisor)
This project deals with the design of dual band antenna for the receiving of Wi-Fi signal integrated to the USB key receiver, which can be connected to notebook or PC with the help of interface and receive available Wi-fi signal . The center frequencies were chosen for 2,4 GHz and 5 GHz where the Wi-Fi signal operates and for these frequencies the antenna has been tuned. The antenna has been designed and simulated in CST Microwave Studio 2010. The first part of this work deals with the design of dual band antenna. Next, the resonant frequencies of the antenna are optimized in order to compensate the influence of the plastic housing and the electronic part of the USB key.

Computer modeling of implantable antennas
Deneš, Roman ; Kadlec, Petr (referee) ; Raida, Zbyněk (advisor)
The thesis deals with a design of planar antennas and their simulation in the vicinity of a human body. The main goal of this thesis is parametrically analyse different types of planar antennas and find out which one possesses the highest quality in the vicinity of a human body. The design and simulation were made in a software called CST Microwave Studio. Firstly, the attention is paid to the concept of designing and simulation. Further, they are made and tested.

Antenna for in-car UWB communication
Špůrek, Jan ; Puskely, Jan (referee) ; Raida, Zbyněk (advisor)
This bachelor’s thesis is focused on the design of a wireless UWB network inside a car. The project is divided into three parts. In the first part, we describe the design of suitable antennas and feeding structures. The second part is focused on the simulation of a reciprocal communication for each type of the antenna in free space. In the third part, we investigate the effect of interference caused by near parts of the car for each type of the antenna. The results are then evaluated and the most suitable antenna is chosen for realization. The fourth part describes modifications of the antenna for SMA connector, which is necessary for measurement. In the fifth part we discuss measured results and compare them with assumptions from simulations. Results of the thesis are summarized in the conclusion.
