Planar mono- and dipole antennas for on-body communication
Maro, Ivan ; Láčík, Jaroslav (oponent) ; Raida, Zbyněk (vedoucí práce)
This bachelor’s thesis is focused on designing and simulating several types of monopole and dipole textile antennas, which will be used for ON-body communication in ISM 5.8 GHz frequency band. It also examines the possibility of using a reflector made of artificial magnetic conductor to achieve an overall improvement in antenna parameters. The antenna has been subjected to bending, to ensure proper functionality when placed on different parts of the body. For selected antennas, a specific absorption rate SAR was also simulated so that the antenna meets the required limits specified by the competent authorities. Subsequently, two antennas were chosen for prototype production, which were produced by silkscreen printing technique. The manufactured antennas were measured in an anechoic chamber and their results compared with simulations.

Filtering antenna based on coaxial cavity resonators
Maro, Ivan ; Vrba, David (oponent) ; Raida, Zbyněk (vedoucí práce)
This semestral thesis is aimed at verifying the functionality of the proposed concept of a tuneable filtering antenna. The antenna is designed in such way that it combines the filtering and radiating functions into a single unit. After simulating and verifying the correct functionality of the proposed antenna [1] in an electromagnetic simulator, thesis than discusses the possibilities of improving the antenna parameters. To achieve higher directivity and gain, a solution is proposed where a pyramidal horn antenna is added at the end of the filtering waveguide. Obtained results are than used to design antenna integrated into substrate.
