Abstract
Briefly, in accordance with one embodiment of the invention, an antenna may comprise a first radiating element to provide a first axis of polarization, and a second radiating element to provide a second axis of polarization. The first axis of polarization may be orthogonal or orthogonal at least in part, to the second axis of polarization. The first and second axes together may result in an omnidirectional, or at least partially omnidirectional, gain pattern for the antenna. RF signals may be propagated on the first and second axes using the same communication standard on both axes, and/or using a different communication standard on each of the axes. In accordance with one or more embodiments, the first axis of polarization may be utilized for a first MIMO communication channel, and the second axis of polarization may be utilized for a second MIMO communication channel.
