Is it feasible to use multiple (e.g. 2) independently transmitting antennas on the same PCB (e.g. 5cm x 5cm) operating in the same band (e.g. 2.4GHz), though on different "frequency channels"?
I'm not sure what the radiation pattern looks like for typical PCB or modular 2.4GHz antennas, but I am wanting to have a device receive a data stream on one antenna via a (fast) proprietary protocol, and interact with another device via BLE on the other antenna. Unfortunately the throughout needs are too high to use a single antenna with modern SoCs (e.g. from Nordic).
I was hoping if I was able to space the antennas out by about 5cm and orient them in opposite directions, then there would be minimal interference assuming different frequency channels were used.
Any explanation on why or why not this would work would be much appreciated. Thanks
