Abstract: The Active Electronically Scanned Lens Array design for a phased array reduces the cost of the phased array with minimal sacrifice to array performance. The design replaces transmit/receive (T/R) modules at the front end of the array with low cost and low lost phase shifters. A tradeoff in this design is a periodic phase quantization error that leads to quantization lobes. To reduce quantization lobes, a phase addition approach is presented to break up with the periodicity. In the presented approach, a phase offset is added at a T/R module and then corrected for at each radiating element in the array. The applied phase offset can be either deterministic or random.

Abstract: An antenna is provided from a plurality of antenna elements, each having a pair of orthogonally coupled notch elements coupled to an interleaved stripline-to-slot feed structure. Each dual-polarized, interleaved tapered slot antenna element forms a building block and a plurality of such tapered slot antenna elements can be arranged to form a phased array antenna having a triangular lattice pattern. The phased array antenna is capable of receiving electromagnetic signals having orthogonal polarization and includes a feed structure which provides interconnections on a single plane. The structure of the tapered slot antenna structure provides wideband, wide scan performance, for multiple polarizations without requiring electrical continuity between adjacent notch antenna elements.
