One of the circuit boards I’m developing would benefit from an onboard antenna, so I started hunting for design tips. The following three PDF documents do a great job of explaining the basics:
Freescale “Compact Integrated Antennas“ Kent Smith “Antennas for low power applications“ Ingecom “V / UHF Antenna Design“ I will update the blog once the circuit board is designed and I have managed to test range and effectiveness.
