Latest Patents

One of his latest patents is titled "High uniformity microstrip to modified-square-ax interconnect." This invention features a very low reflection transition with tightly controlled variability between a rectangular coaxial transmission line and a microstrip transmission line. The design includes an extended microstrip ground plane under the transition region, forming a transition ground plane. Additionally, the upper portion of the dielectric of the rectangular coaxial transmission line is removed at the transition region, along with the upper portion of the center conductor. The spacing between the transition center conductor and the ground plane is reduced, enhancing performance. A tuning cavity is also formed in the transition ground plane beneath the transition center conductor.

Another significant patent is the "Rectangular coaxial line to microstrip line matching transition." This microwave circuit includes a rectangular coaxial transmission line, a microstrip transmission line, and a wideband transition section for transitioning between the two. The transition section features a capacitive section that cancels inductive reactance caused by physical discontinuities at the transition junction. A conductive tab extends from the rectangular coaxial center conductor, electrically connecting to the microstrip conductor line. The capacitive section can be a dielectric disk with a greater dielectric constant or an area of increased cross-sectional dimension of the rectangular coaxial center conductor.
