Latest Patents

His latest patent involves a low profile active electronically scanned antenna (AESA) designed for Ka-band radar systems. This innovative antenna features a vertically integrated design that includes a transitioning RF waveguide relocator panel located behind a radiator faceplate. The system incorporates an array of beam control tiles that are coupled to multiple transceiver modules via an RF manifold. Each beam control tile consists of high power transmit/receive (T/R) cells, dielectric waveguides, RF stripline, and coaxial transmission line elements. The waveguide relocator panel is fabricated using a diffusion bonded copper laminate stack with dielectric filling, while the beam control tiles are made from multiple layers of low temperature co-fired ceramic (LTCC) material. This design effectively routes RF signals to and from the transceiver modules and includes features to prevent RF leakage and ensure efficient cooling.
