Advanced Antenna Array Beamformers

Array antennas are conglomerations of many small radiating antennas, referred to as array elements. In common antenna pattern analyses the element pattern is considered to be uniform; element to element. Overall transmit or receive patterns are then described as products of two factors: the element pattern and the, so-called, array factor. Practical small array antennas may not conform to the above assumptions, since their elements may be influenced differently by their physical environments. This may cause theoretical patterns to become degraded. In this SBIR effort, TSC proposes to improve the antenna pattern performance of an existing legacy array via corrective phase and/or amplitude controls at its individual elements, through the implementation a powerful optimization technique whose effectiveness and efficiency has already been demonstrated in other antenna and waveform design applications. Though the application of this technique to the actual legacy array description and measurements, TSC proposes to demonstrate the feasibility limit of such optimization, subject to low insertion loss requirement, over narrow and wide bands, and on both transmit and on receive.
