Abstract:
A Wi-Fi antenna device is disclosed. The Wi-Fi antenna device comprises a ground plane, a plurality of first inverted-F antennas, a plurality of second inverted-F antennas and a plurality of third inverted-F antennas, thereby being capable of transceiving multi-band wireless signals. Particularly, there is an included angle between any two of the first inverted-F antennas. In the same way, any two of the second inverted-F antennas and any two of the third inverted-F antennas are both arranged to have said included angle therebetween. By such an arrangement, an omni radiation pattern can be measured on X-Y plane, X-Z plane and Y-Z plane in case of this novel Wi-Fi antenna device being applied in an environment. Therefore, the Wi-Fi antenna device according to the present invention has a significant potential for replacing the conventional multi-band antenna so as to be applied in a Wi-Fi router.
