Our PCB is small and long, to fit in a small tube (scientific long-term data logger for natural hazards, runs up to >10 years with one battery set, using 2G / LTE-M1, local communication is with BLE 5.0, system supports secure FOTA via BLE and 2G/LTE-M1. If anybody is interested: please let me know ;-) ),
124mm long and 19.5 mm height. We are using a SARA-R412-Modem in Europe,
First Samples (on a much broader) PCB with "Lucida" worked excellent, but now for the small PCB: Which Antenna could be used?
Thanks for any suggestions!
