Hi,
I did try asking the same question here but didnt get any reply after sometime, so creating a new thread. Sorry for that. Meanwhile I've updated my design and need final check.
4 Layer - Same as Read Me file in the reference design
I tried my best to do following things
- Continuous GND plane underneath RF section. No routing underneath that area.
- TOP and Bottom Copper pour connected with lots of vias to GND plane.
- Followed MIFA dimension mentioned in AN043 guide.
- Maintain 50 ohm impedance for RF trace
- No copper on any layer underneath Antenna section
Question: I have put a polygon cutout around Antenna tuning Capactior. is it okay?
Any other suggestions are welcome.
