A thermal management system and process for use in a wireless access point antenna housing. The access point typically includes two or more stacked antenna housings or bays. Each bay includes an upper end, a lower end spaced from the upper end, and at least one sidewall surface extending between the upper end the lower end to define an enclosed interior area of the bay. Each bay typically includes a plurality of antennas. In an arrangement, the upper end, lower end and a one or more partitions between the upper and lower ends in conjunction with one or more sidewall surfaces form the antenna bays. In an arrangement, divider panels form the partitions and/or the upper and lower ends. Each partition panel includes one or more airflow channels that provide an air inlet and/or outlet for at least one adjacent antenna bay.

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.

An antenna housing configured to house a wireless antenna unit. The antenna housing defines an interior space sized to receive a plurality of wireless radios and/or transceivers. Inlet and outlet ducting extends through the interior of the housing from an inlet manifold to an outlet manifold to individually cool each radio. In an arrangement, the inlet manifold draws air from outside the housing and the outlet manifold exhausts air outside of the manifold.
