Hey everyone,
The CC-Antenna-DK2 "quick start guide" (and the antenna PCB silkscreen itlself) mentions that antenna #11 has a dual band option for 868MHz and 2.4GHz. However the kit schematic represents the used BOM as the single band option. The "CC-Antenna-DK2 and Antenna Measurements Summary (Rev. A)" also doesn't mention anything about the dual band option for 868. And ultimately DN007 also only refers to it as a 2.4GHz antenna.
So is this antenna capable of dual band or not? If so, how can we achieve it?
Thank you.
Yes, the dual-band function is due to the antenna match; refer to application note SWRA640 that explains the matching process for dual-band operation.
Ok, thanks Richard. I thought there might be some documentation specifically about that antenna.
