**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:
www.johansontechnology.com/tuning and see how to obtain the new values. If you need further
