Claim Text:
1. A method, comprising: introducing a phase difference between signals at antenna ports of an antenna structure such that a first signal at one of the antenna ports has a different phase than a second signal at another one of the antenna ports to provide antenna pattern control and to increase gain in a direction toward a far-field point, wherein the antenna structure comprises a plurality of antenna elements, each operatively coupled to a different one of the antenna ports, wherein electrical currents flowing in the antenna structure are such that the antenna ports are isolated at a desired signal frequency range; and operating at a reduced power that is lower than a power used in a non-pattern control operation of the antenna structure such that a communications device utilizing the antenna structure satisfies an equivalent wireless link performance with the far-field point using reduced power compared to the non-pattern control operation, thereby reducing a specific absorption rate.
