Latest Patents

One of his latest patents is titled "Hybrid horn for dual Ka-band communications." This invention features a Ka-band horn designed for efficient transmission and reception of information between a ground station and a satellite. The horn consists of three sections, with the throat segment specifically adapted for coupling to a feed. It includes circular, alternating grooves and webs that widen towards the horn's aperture, ensuring optimal impedance matching. The middle segment incorporates dual depth corrugations, allowing the horn to achieve a near-HE11 mode at its aperture. The final segment is a truncated, smooth-walled cone, enhancing the overall performance of the horn.

Another significant patent is the "Multi-band corrugated antenna feed horn with a hexagonal aperture and antenna array using same." This invention is designed for use in a multiple-feed antenna system. It comprises a corrugated feed horn and an antenna array arranged in a hexagonal lattice pattern. The feed horn features a hexagonal aperture formed by a circular-to-hexagonal transition section, along with a tapered section and an input section. This innovative design improves beam pattern symmetry, reduces cross-polarization, and enhances efficiency by transitioning from a circular to a hexagonal aperture.
