Thingy 52 reference design for pcb antenna and chip antenna

[ketan]

Hello,

For implementation of PCB trace antenna and PCB chip antenna on same PCB can we consider Thingy 52 reference design?

Thanks

Hello ketan

The thingy only has one 2.4GHz antenna, the 2450AT18B100 ceramic chip antenna from Johanson. You can find the thingy's hardware files here. If you use this specific chip antenna you can copy the layout surrounding the antenna. As I wrote in my answer in this case if you want dual antennas you will need a RF switch to isolate the two antennas from each other. You may also have to tune the matching networks to compensate for additional parasites.

Best regards
