Antenna with polarization diversity
First Claim
1. An antenna system, comprising:
- a horizontally polarized omnidirectional antenna array extending along a first plane, the horizontally polarized omnidirectional antenna array comprising a plurality of antenna elements having a pre-defined configuration;
a vertically polarized omnidirectional antenna array extending along a second plane intersecting the first plane; and
connection elements for coupling each of the antenna arrays with dedicated and different radios, wherein the connection elements comprise a printed circuit board associated with the horizontally polarized omnidirectional antenna array, the printed circuit board having a slit therein configured to couple the horizontally polarized omnidirectional antenna array to the vertically polarized omnidirectional antenna array when the vertically polarized omnidirectional antenna array is inserted into the slit.

Abstract
A horizontally polarized antenna array allows for the efficient distribution of RF energy into a communications environment through selectable antenna elements and redirectors that create a particular radiation pattern such as a substantially omnidirectional radiation pattern. In conjunction with a vertically polarized array, a particular high-gain wireless environment may be created such that one environment does not interfere with other nearby wireless environments and avoids interference created by those other environments. Lower gain patterns may also be created by using particular configurations of a horizontal and/or vertical antenna array. In a preferred embodiment, the antenna systems disclosed herein are utilized in a multiple-input, multiple-output (MIMO) wireless environment.
