Mounting Considerations
Line width should be designed to match 50Ω characteristic impedance (Grounded Co‐Planar Waveguide), depending on PCB material and thickness. (The matching circuit and component values will be different on clients PCB layout, se notes below and go to page 2 for details).

Go to page 2 for details.
Note: It is recommended that the designer leave available slots for a "pi" (or shunt-seriesshunt) 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
