5 Conclusion
Different matching network have been designed and measured. Among those different circuits, the best
has been proposed for each antenna and each product.
Proposed matching network are the same for the product couple WNAL63/WNAL23 & WNAL43/WNAL33:
product with same PCB.
With those matching network radiated power has been improved:
 between 2.3 & 4.3dB depending on frequency for the WNAL63 product
 between 3 & 4dB depending on frequency for the WNAL23 product
 between 0 & 2dB depending on frequency for the WNAL43 product
 between 0 & 1.5dB depending on frequency for the WNAL33 product
Based on measurement done, we noticed that gain variation between two product with the same PCB is
depending on the way to mount product, especially metallic hubcap.
