Unfortunately, it looks like I have a Bluetooth design that could be prepared for production in the next few months... Never done anything with antennas or intentionally radiated anything. I have some learning and preparation to do.
For the prototype, I just banged together the patch antenna based on recommendations from a TI app note and taking coarse measurements from other bluetooth devices. It seems to work.
I suppose I should actually tune the antenna on its production PCB, so I should find a 2.4 GHz VNA? Or maybe a 2.4 GHz spectrum analyzer and signal generator would be enough?
If my employer pays, I figure the Rigol DSA832-TG would be the low-end of what I would need. If I'm paying for it, I might try to make old equipment work, maybe a 8594E and 8616A/8340/8341. I avoid renting because I always need a device a week after returning it but, if the alternative is having $25k of RF equipment lying around, then no problem!
I can ensure the rest of the board is quiet. Anything else I need to worry about? Random thoughts from anyone who's been here before? Thank you!
