This single polarized panel antenna works in the 5.2 to 6.1 GHz band and exhibit the very desirable feature - the reduced SLL (Side Lobes Level). The first side lobes are reduced by at least 20 dB compared to the main beam level in the upper operational frequency band.

In the real Wireless Lan systems it will receive less interference signals from other directions than the main beam direction. This mechanism will  also work in a transmit mode - the antenna will send signals with less power to other directions.

In the other word, the antenna alone will increase the Signal-to-Noise ratio and thus the system performance.
