5.2 Matching Circuit
Like all antennas, surrounding components, enclosures, and changes to the GND plane
dimensions can alter performance. A pi-matching network like the one shown below is required
in case adjustments need to be made. The antenna EVB has a similar matching network. The
components on the EVB are a good starting point for a new design, but will need to be adjusted
upon integration for best performance. The zero ohm resistor is needed for the ability to solder
down a coax pigtail to make measurements with a vector network analyzer.
