For the best possible antenna performance, it is important that the antenna design has been properly arranged.
nWP033 - nRF9160 Antenna and RF Interface Guidelines gives recommendations on how to achieve the best possible performance. If good Global Navigation Satellite System (GNSS) and Long-Term Evolution (LTE) performance is important in your application, it is crucial to have a good antenna design as early as possible.
We have several antenna manufacturers as design partners, and we recommend that you contact them early in the hardware design process to get the best possible performance and support.
We also recommend that you learn how you can use the GNSS on the application side for best performance.
