Abstract/Summary:

---

This study presents proof of concept of a silicon PV module integrated monopole and dipole microstrip antenna made for IoT frequencies in Europe, 868 MHz. Proof of concept for two types of PV integrated antennas is made. A monopole antenna with a length of 50 mm with ground attached to a bike stand and a dipole with each pole the length of 52 mm. Both antennas have been tested and compared to an off-the-shelf stub antenna. The monopole showed close to similar or better readings on SF, RSSI and number of packets. The dipole had better readings on SF and RSSI but had lower number of packets sent. The dipole offers the possibility of easy connection whereas the monopole antenna needs to be connected to both a coax cable and the bike stand.
