Miniature antenna for mobile applications
Šmarda, Marek ; Švanda,, Milan (referee) ; Pokorný, Michal (advisor)
This work deals with the most famous constructions of planar antennas. The work analyses selected methods of connecting planar antennas' charging with the possibility of impedance adaptation. An important part of the work consists of description of techniques for increasing bandwidth and conversely techniques for reducing the dimensions which are important for the design of planar antennas for mobile devices. The antennas were designed by means of theoretical basis and their properties were examined in the electromagnetic field simulator. The selected antenna model was constructed and its parameters were measured experimentally. The matching circuit for the antenna to tune it to different resonant frequencies was designed and constructed.

Square type fractal antenna
Roháček, Peter ; Všetula, Petr (referee) ; Hebelka, Vladimír (advisor)
The bachelor thesis deals with analysis of fundamental parameters of antennas and methods of fractal construction. Attention is turn on microstrip antennas, where are discussed the basic properties, the pros and cons, methods of construction, power options and a demonstration of the theoretical proposal. These supporting documents were used for the actual design and optimization of the square fractal antenna in CST Microwave Studio program, which was subsequently implemented.
