I'm in the process of selecting antennas for use with a new design that makes use of the Nordic nRF5340 BLE module and a Telit ME910G1-WW MODEM. The MODEM Is a dual mode LTE-M/NB-IoT 4G device with 2G fallback. Both of the antennas are to be situated on a daughter-board in a dome that sticks out of a metal housing. In previous (2G only) versions of the product we made use of the Calvus which performed brilliantly. We're now looking to update the design and pick an appropriate replacement. Any help/advice you can provide will be greatly appreciated.
