Abstract
An antenna array especially for use on mobile platforms, which provides the spatial discrimination in selected directions required for such antennas. The shape of the radiation pattern of the antenna array is modified dynamically, such that the gain in the direction of other sources is sufficiently low to meet the desired or required spatial discrimination to avoid any significant interference with the other sources. The pattern is controlled by controlling the amplitude and/or the phase of one or more elements within or outside the antenna array. In this manner reduced gain or nulls can be directed at the potentially interfering sources, which are not being utilized by the antenna array for communications.
