ANTENNA ASSEMBLY

摘要

Antenna assemblies are described herein. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly may include a primary reflector, a secondary reflector, and a primary feed that is feed by multiple antenna input feeds so that different regions of the primary and secondary antenna correlate with different beams emitted by the primary feed. The antenna assembly is capable of emitting beams in the same direction having different polarizations using a single primary feed. Also described herein are methods of operating an antenna assembly. Access point devices that have a single primary feed configured to emit multiple beams are also described.

1. An antenna assembly comprising:
a primary reflector having a concave reflecting surface configured to direct electromagnetic energy; a secondary reflector within the primary reflector having a convex reflecting surface configured to direct electromagnetic energy toward the primary reflector; a primary feed having a patterned emitting surface; three or more antenna input feeds each connected to the patterned antenna emitting surface of the primary feed; and three or more connectors exposed on an external surface of the antenna assembly wherein each connector is configured to couple to one of the three or more antenna input feeds and configured to transmit radio frequency (RF) signals at a different polarization to each of the antenna input feeds.
