**Note 2: It is recommended that the designer leave
available slots for a "pi" (or shunt-series-shunt) network.
The antenna matching network values above are used
when antenna is mounted on Johanson's evaluation board.
The matching values on client's PCB will be different. Go
to: http://johansontechnology.com/tuning and see how to
obtain the new values. If you need further antenna
assistance help, contact our RF Applications Eng Team at:

*Line width should be designed to match 50Ω characteristic
impedance, depending on PCB material and thickness. Grounded
CPWG will provide best results!
