Hello everyone,
I am currently working on a project using the RAK3172 module and am looking to implement a PCB antenna solution without the IPEX connector. Specifically, I am interested in alternative antennas, such as SMD chip or ceramic antennas that operate at 868 MHz with 50 Ohm impedance.
Would anyone have experience or reference schematics for using a PCB antenna with the RAK3172 module instead of the IPEX connector? Any advice on layout guidelines or recommendations for a chip/ceramic antenna model would be very helpful.
