Vertically polarized Yagi antenna with magnetic dipole
Weigel, Filip ; Pokorný, Michal (referee) ; Raida, Zbyněk (advisor)
This bachelor’s thesis deals with the principles of operation and simulation of planar Yagi antennas with a magnetic dipole. Simulation of electromagnetic field was performed in the simulator CST MICROWAVE STUDIO (CST MWS). The project compares results of simulations of several types of Yagi antennas. These antennas can be used for the communication along the living tissue (on-body communication).

Patch antenna with switchable polarization
Havelka, Michal ; Pokorný, Michal (referee) ; Raida, Zbyněk (advisor)
The bachelor’s thesis deals with the analysis of basic planar antennas, the design methods, optimization and simulation in ANSOFT Designer. Attention is turned to the design of aperture coupled microstrip antennas. First, the antenna with a simple slot is designed. Second, the design of the ring slot coupled microstrip antenna is described. Both the antennas are designed for the operation frequency 2,45 GHz. The second part is devoted to the antenna with switchable polarization. Using three PIN diodes powered by lithium battery of 3-V, the linear polarization (both the horizontal one and the vertical one) and the circular polarization (both the right-hand one and the left-hand one) can be switched. The results were verified by experimental verification.

Substrate integrated dielectric resonator antenna
Jedlička, Lukáš ; Horák, Jiří (referee) ; Mrnka, Michal (advisor)
The bachelor´s thesis deals with the design of the dielectric resonator antenna in the microwave band X, where the resonator is made by air perforations. The antenna is made by two layers. The antenna is supplied by the substrate integrated waveguide. The design of the dimensions to achieve the desired resonance frequency of the dielectric resonator and integration of resonator is described. The whole antenna is designed in the CST Microwave Studio software.
