Embodiment Construction

[0032] In some embodiments, internal cross-polarized antennas may be implemented in a small form factor multi-stream MIMO access point. In these embodiments, each of the antennas may be located within the access point with, for example, vertical polarization or horizontal polarization. A MIMO access point can be a dual radio access point in that the internal antennas of the access point can operate in both the 2.4GHz band and the 5.0GHz band. The implementation of cross-polarized internal antennas generally involves considerations of various aspects such as radio frequency (RF), thermal characteristics, mechanical mechanisms, and / or electrical mechanisms. Also, in some embodiments, polarization diversity may be implemented in the design of small form factor MIMO access points in addition to standard pattern diversity and spatial diversity. As a result, maximum diversity among internal antennas within a multi-stream MIMO access point may be obtained, thereby improving the perf...

Abstract

An apparatus for implementing a cross-polarized integrated antenna for a MIMO access point. The device includes a processor disposed within the outer enclosure and configured to connect one or more wireless devices to a network. The first antenna has a polarization orientation and is disposed within the outer enclosure. The second antenna has a polarization orientation and is disposed within the outer enclosure at a non-zero distance from the first antenna. The third antenna has a polarization orientation and is disposed within the outer enclosure at a non-zero distance from each of the first and second antennas. The polarization orientation of the first polarization is different from the polarization orientation of the second antenna, and the polarization orientation of the third antenna is different from the polarization orientation of the first antenna and the polarization orientation of the second antenna.
