6.2 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 the

same 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.
