4 Conclusion
Zigbee or Wifi antennas are not well matched with matching network used by default. New matching
networks are necessary.
Different matching network have been designed and measured. Among those different circuits, the best
has been proposed for each antenna. With those matching network radiated power has been improved by
 2.1dB at 2412Mhz, 1.3dB at 2442 and 0.6dB at 2480MHz for Wifi
 2.3dB at 2405Mhz, 3dB at 2440 and 3.4dB at 2480MHz for Zigbee
