Hi !
My first post in this forum, so be gentle 
Im about to design a folded dipole antenna for the CC2420, however the datasheet leaves some questions unanswered.
All the other designs of folded dipoles have seen uses DC-decoupling capacitor i series with the feeder. The CC2420 does not.
The CC2420 datasheet also specifies a capacitor not shown on the “Folded-dipole-antenna” Figure, but included in the table below.
Where can I find some extensive study material about folded dipole antennas in general?, or specifically for the CC2430 if avaliable?
Mvh
