5.2 Solder Land Pattern

This antenna includes a fine tuning element (as shown in the land patterns above)

that can be used to slightly shift antenna resonance.

5.3 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.
