Design of antenna for LoRaWAN module
Paulysko, Tomáš ; Láčík, Jaroslav (referee) ; Bednarský, Vojtěch (advisor)
This bachelor thesis focuses on the design, optimization, and implementation of compact antennas for LoRaWAN modules operating in the European 868 MHz frequency band. The goal is to create antennas that are not only effective and compact but also easily integrated into 3D printed enclosures of IoT devices. During the work, three different configurations of microwave structures containing antennas were designed and numerically modeled. These antennas were subsequently manufactured and tested. The measurements demonstrated their ability to achieve a reflection coefficient below -15 dB. The best structure achieved a realized gain of 1.13 dBi. The work also highlights the need for further tuning and adaptation of antennas to ensure optimal parameters in various applications.

Modeling antennas of the VUT 100 aircraft
Starý, Vladimír ; Tobola,, Pavel (referee) ; Raida, Zbyněk (advisor)
The thesis is aimed to analyze parameters of antennas, and work out the computer, which can be used to the modeling of the radiation of antennas of the VUT 100 aircraft. First, used antennas are divided according to the operation frequencies, and the polarization. Second, a MATLAB program is developed and described. The program computes radiation patterns at different frequencies for the different location of antennas on the VUT aircraft. Finally, the MATLAB optimization program is develop and described. The program changes the position of antennas so that the requirements of aircraft producer can be met.
