Latest Patents

One of his latest patents is the "Lossless Annular Rotary RF Coupler." This invention features an annular rotary RF coupler designed for installation around a vertical support structure, such as the mast of a ship. The design includes two annuli divided into circumferential increments, creating a cellular structure of individual waveguide cross-sections. The lower annulus, or stator, remains fixed, while the upper annulus, or rotor, rotates with respect to the lower one. This configuration allows for efficient power distribution and minimizes energy loss.

Another significant patent is the "Around-the-Mast Rotary Coupler with Individual Power Module Excitation." Similar to his previous invention, this coupler is designed for vertical support structures and features two annular volumes divided into circumferential increments. The fixed stator is fed in equal phase from individual solid-state transmit/receive modules, while the rotor rotates around a common mechanical center. This design enhances the performance of mechanically rotating antenna systems.
