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.
