Otherwise, the antenna will not operate as intended. Want the layout file of this? Send us a message at: Ver 3.0 2It is recommended that the designer leave available slots for a "pi" (or shunt-series-shunt) network, even if all slots won't be used, this will prepare the PCB for the final mass production values of the matching circuit. 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 yourself if you have a network analyzer.
