Abstract: A method, apparatus and computer program product are provided disable one or more antennas of an antenna array in order to achieve a predefined objective while selectively utilizing the remainder of the antennas of the antenna array. The one or more antennas to be disabled are selected in a manner to avoid appreciable impact to the fidelity of the resulting array radiation pattern. For example, the method, apparatus and computer program product may disable certain antenna elements based upon the distance of the antenna elements from a predefined location relative to the antenna array, such as the distance from the center of the antenna array, and may selectively utilize the remainder of the antenna elements such that an active portion of the antenna array approximates a circular array which results in an array radiation pattern for which the fidelity is maintained.

Abstract: The invention is a combiner and a method for selectively combining modulated signals. The combiner includes a first modulator (12) with a selective input which receives at least one input signal and a first carrier signal and which outputs a first output modulated with the first carrier signal; a second modulator (14) with a selective input which receives at least one input signal and a second carrier signal and which outputs a second output modulated with the second carrier signal; means for combining (24?) the first and second amplified output signals to provide a combined output; and wherein the first and second carrier signals are selectably coherent or incoherent with the selection of first and second coherent carrier signals causing the combined output to comprise a single carrier of higher power and the selection of incoherent carrier signals causing the combined output to comprise two distinguishable carriers of lower power.
