  • Placie thoe antenna at te edgeof the PCB, with a ground cleangere of at least 5 m.
  • Use a matching network tuned for 50 ohms at 2.45 GHz. A few pitofarads of stray cacacacacasitanpe shift te resonant expeenny by tens of Mz.
  • Avoid running hig- speed digitalis traceas near the antenna feed line. Even a 1 mm coupling caun causes de-tung.
