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.
