4 Radiated measurements
The measurements were carried out for the H and E planes at the2405, 2440 & 2480MHz frequencies in
vertical and horizontal polarization with a step of 1 °. From these results the total polarization was
calculated.
Measurements have been done using the modem of each product for the antenna matching circuit used by
default and for the antenna matching proposed for each product.
The H, and E plane are displayed below :

Because all products were not set-up at maximum power, we have normalized the power at the maximum
power given by the measurement carried out at the modem output for each of the products. This will allow
comparing radiated performances among products tested.
It means that,
 For product WNAL23 with and output power measure at the antenna port at -12.3dBm at 2405, 2440
& 2480MHz, an offset have been applied to reach the maximum power output delivered at the
antenna port for the WNAL33 product.
 For product WNAL63 with and output power measure at the antenna port at -12dBm at 2405MHz, -
12.8dBm at 2440MHz & -13.7dBm at 2480MHz, an offset have been applied for each frequency to
reach the maximum power output delivered at the antenna port for the WNAL33 product.
 For product WNAL33 with and output power measure at the antenna port at 5.5dBm for 2405, 2440
& 2480MHz, no offset have been applied since it was the maximum power measure among all
product.
 For product WNAL43 with and output power measure at the antenna port at 5.5dBm for 2405, 2440
& 2480MHz, no offset have been applied since it was the maximum power measure among all
product.
