PCA10000 vs PCA20006 for better range

[Jose Xavier]

Hello,

I have a development kit with the PCA10000 and I can comunicate with the PCA10004 for about 5/6 meters what is ok for my application but now I want to comunicate using two small pcbs like PCA10000 that I'll design. To get best range result should I use PCA10000 or PCA20006 antenna reference design?

Thank you

If you have room for the antenna implementation as it's done on the PCA10000, that would be the recommendation as this board has a larger ground plane and an overall better antenna implementation. Keep in mind that antenna characteristic is not set in stone. So one antenna implementation that works will in one design, might change when used in a different design. The antenna characteristics are dependent on size and shape of the antenna, size and shape of the ground plane, distance to other metal objects/skin and housing. For the two boards you are using as reference, the antenna implementation on the PCA10001 would be the one I would recommend to follow.
