Hello,
There is a useful post on Anrennas on this link:
https://forum.digikey.com/t/radio-frequency-rf-antennas/24009
There are also posts on the transmitters and receivers on this link : Search results for 'rf transmitter' - Engineering and Component Solution Forum - TechForum │ Digi-Key
I did not narrow down either search . This should help on the selection.
