Dual band dual polarization antenna array
First Claim
1. A dual band antenna system, comprising:
- a horizontally polarized antenna array configured to concurrently operate at a plurality of frequencies, wherein the horizontally polarized antenna array includes a first antenna element and a second antenna element, and wherein the first antenna element is positioned outside of radiation produced by the second antenna element;
a vertically polarized antenna array coupled to the horizontally polarized antenna array and configured to concurrently operate at the plurality of frequencies with the horizontally polarized antenna array; and
an antenna selector configured to communicate a radio frequency signal with selected antenna elements of the horizontally polarized antenna array and vertically polarized antenna array.

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.
