New potential of a direct printed LoRa antenna
Résumé
In order to minimize the PCB (Printed Circuit Board) footprint of an IoT microtracker, we analyse the opportunity of deporting a LoRa antenna on the plastic case of the microtracker. This paper aims to compare an antenna conventionally manufactured on a PCB (FR4) and a printed antenna using jetting technology on a PC+ABS (Polycarbonate and Acrylonitrile Butadiène Styrène) polymeric substrate. The influence of the conductive ink, the antenna design and the substrate are underlined.
