Note: It is recommended that the designer
leave available slots for a "pi" (or shunt-
series-shunt) network. The antenna
matching network values here are used
when antenna is mounted on Johanson's
evaluation board. The matching values on
clinet's PCB will be different, go to:
johansontechnology.com/tuning and see
how to obtain the new values. If you need
