Patent ID: 8547289

Claim:
An antenna structure that operates in a frequency range, the antenna structure comprising: a plurality of antenna ports; a plurality of antenna elements, wherein each of the plurality of antenna elements is coupled to a different one of the plurality of antenna ports, and wherein each of the plurality of antenna elements operates in a frequency range; and one or more elements electrically coupling the plurality of antenna elements, wherein electrical currents on one of the plurality of antenna elements flow to a neighboring one of the plurality of the antenna elements bypassing one of the plurality of antenna ports coupled to the neighboring one of the plurality of antenna elements, wherein the electrical currents flowing through the one of the plurality of antenna elements and the neighboring one of the plurality of antenna elements have a magnitude such that a first antenna mode excited by one of the plurality of antenna ports is substantially electrically isolated from a second antenna mode excited by another one of the plurality of antenna ports at a desired signal frequency range without coupling a decoupling network to the plurality of antenna ports, and wherein the antenna structure generates diverse antenna patterns.
