Attention: Matching circuits and component values will be different on the
client's design, depending on PCB layout, geometry, etc. It is recommended
that the designer leave available slots for a "pi" (or shunt-series-shunt) network.
The antenna matching network values you see here are used when antenna is
mounted on Johanson's evaluation board.
Need help laying out the antenna, want us to review your antenna design
(free!), require the Gerber files for this EVB, or would like us to validate the new
tuning values of your PCB (fee may apply) go to:
www.johansontechnology.com/ask-a-question
Orderable EVB for evaluation, it comes with a female SMA connector. Go to:
www.johansontechnology.com/component/samplerequest and ask for p/n
2450AD47A1590-EB1SMA
*
Line width should be designed to match 50Ω characteristic impedance,
depending on PCB material, thickness, and preferably CPWG (co-planar wave
guide) type.
