A scannable antenna having a radiating array of antenna elements correspondingly coupled, through equal line lengths, to a more closely spaced array of antenna elements positioned in a space coupling region. A feed array of antenna elements, with spacings substantially equal to the spacing in the radiating array and substantially of the same physical size as the more closely spaced array, is positioned in the space coupling region in close proximity, no more than a wave length away, to the more closely spaced array. The feed array is coupled to a distribution network which provides desired phase and amplitude aperture distributions.

An apparatus and method for scanning a circular array through 360. degree. with tapered aperture illumination function to achieve radiated beams with desired sidelobe levels. A switching matrix selects a predetermined number of active elements from the total number of elements disposed about the circle to form a sub-array. To this sub-array a variable amplitude distribution network is coupled to establish excitations at each active element in accordance with a desired amplitude distribution function.
