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:

*Line width should be designed to match 50ohm
characteristic impedance, depending on your PCB
material and thickness (distance to GND). CPWG (coplanar waveguide) trace type strongly suggested.

Note: Matching circuits and component
values will be different on the client's
design, depending on PCB layout,
geometry, encasement, etc. It is
recommended that the designer leave
available slots for a "pi" (or shunt-seriesshunt) network. The antenna matching
network values you see here are used
when antenna is mounted on Johanson's
