Van Atta Antenna Array with Patch Elements and Substrate Integrated Waveguide: 11,121,463


A Van Atta antenna array comprising a number of antenna elements electrically connected to operate as a Van Atta antenna array and fabricated on and within a substrate. Each antenna element has a number of patch elements fabricated on the top surface of the substrate, with the patch elements being interconnected by substrate integrated waveguides. The antenna array provides a two-dimensional retro-reflective surface, which makes it especially suitable for InSAR monitoring of infrastructures.
