Planar mono- and dipole antennas for on-body communication
Maro, Ivan ; Láčík, Jaroslav (referee) ; Raida, Zbyněk (advisor)
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 (referee) ; Raida, Zbyněk (advisor)
Táto práca je zameraná na overenie funkčnosti navrhnutého konceptu laditeľnej filtračnej anténny. Anténa je navrhnutá tak aby spájala filtračnú a vyžarovaciu funkciu do jedného celku. Po odsimulovaní a overení správnej funkčnosti navrhovanej anténny [1] v elektromagnetickom simulátore, sa práca zaoberá možnosťami vylepšenia parametrov anténny. Na dosiahnutie vyššej smerovosti a zisku je navrhnuté riešenie kedy je na koniec filtračného vlnovodu pridaná pyramídová horn anténna. Obdŕžane výsledky sú následne použité pre navh antény integrovanej do subtrátu.
