I have a project for an IoT device with 83mmx40mm PCB size.
We have LTE with GNSS in the same modem and LoRa communication (868MHz).
How could I start search for antennas for coexistence of this 3 bands (GSM, GNSS and LoRa).
I would need PCB antennas to achieve clients requierements for a small device to be hidden. So, we can't use external antennas.
I've been checking your SR4L034 that seems a good option for GSM, but what bout placing other antennas for GNSS and LoRa, what should be the best placement?
I would apreciatte any PN suggestions and getting guidelines for placement and routing on a 4 or 6 layers PCB.
