DUAL-POLARIZED WIDEBAND RADIATOR WITH SINGLE-PLANE STRIPLINE FEED

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...

Summary: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.
