Latest Patents

One of his latest patents is titled "Planar surface features for waveguide and antenna." This document describes techniques and systems for planar surface features for waveguides and antennas. Two structures are arranged with opposing planar surfaces fixed adjacent to a separation plane dividing a channel to provide an energy path for propagating electromagnetic energy. Part of the channel is formed between side walls of a recessed groove within one opposing surface, while another channel part is formed by an arrangement of surface features spaced and shaped on the other opposing surface. At least two surface features are adjacent protrusions contoured to complement the sidewalls of the recessed groove. An area on each opposing surface between the recessed groove and the adjacent protrusions is configured to form the energy path through the channel, including to prevent energy leakage from the separation plane dividing the channel.

Another notable patent is the "Wave-shaped ground structure for antenna arrays." This document describes techniques, apparatuses, and systems for a wave-shaped ground structure for antenna arrays. A radar system may include a ground structure with a first surface having a wave shape and a second surface opposite the first surface. The ground structure includes multiple antenna arrays separated in a longitudinal direction on the first surface. Each antenna array includes one or more antenna elements configured to emit or receive electromagnetic energy. The ground structure also includes antenna feeds separated in the longitudinal direction on the second surface and operably connected to the antenna arrays. The wave shape of the ground structure configures the radar system to provide an antenna radiation pattern that offers a uniform radiation pattern among the antenna arrays.
