**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 help, contact our RF
