Note: 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 monted on Johanson's evaluation board. The
matching values on clinet's PCB will be different. Go to: http://johansontechnology.com/tuning and see how to obtain
the new values. If you need further help, contact our RF Applications Eng Team at:
