Abstract
According to one embodiment of the invention, a wireless network device comprises wireless logic and a heat dissipation unit that encases the wireless logic. The heat dissipation unit includes an antenna dome array that comprises a top surface having a convex-shaped outer periphery with a plurality of antenna elements positioned along the outer periphery.
Claims16
A wireless network device, comprising:
- wireless logic;
- and
- a heat dissipation unit encasing the wireless logic, the heat dissipation unit including an antenna dome array that comprises a top surface having a convex-shaped outer periphery with a plurality of antenna elements positioned along the outer periphery.
An apparatus comprising:
- a cover having a center area and a convex-shaped outer periphery;
- a plurality of antenna elements positioned along a top surface of the outer periphery of the cover, the plurality of antenna elements including a plurality of first antenna elements operating at a first frequency band and a plurality of second antenna elements operating at a second frequency band greater than the first frequency band,
- wherein at least one of the plurality of first antenna elements are positioned on the top surface at a first angle offset from horizontal so as to produce a radiation pattern offset from the horizontal by the first angle.
An access point, comprising:
- a casing;
- a heat dissipation unit encasing by the casing, the heat dissipation unit including an antenna dome array that comprises a top surface having a convex-shaped outer periphery with a plurality of antenna elements positioned along the outer periphery, the plurality of antenna elements including a plurality of first antenna elements operating at a first frequency band and a plurality of second antenna elements operating at a second frequency band greater than the first frequency band,
- wherein at least one of the plurality of first antenna elements are positioned on the top surface at a first angle offset from horizontal so as to produce a radiation pattern offset from the horizontal by the first angle.
