Latest Patents

Okawa's latest patents include a two-port triplate-line/waveguide converter featuring two probes with tips extending in different directions. This invention incorporates a rectangular waveguide and two probes that connect to central conductors of separate triplate lines via slits. These slits are formed separately on two opposing inside walls of the rectangular waveguide, lying on an imaginary straight line that is perpendicular to the inside walls. The two probes, with bent tips inside the rectangular waveguide, function as monopole antennas, utilizing the inside walls as ground planes.

Another significant patent involves a feed line comprised of a triplate line that connects a waveguide/triplate-line converter to multiple patch antennas arranged in a cluster pattern. The design ensures that the width and length of a section of the feed line are optimized to match the impedance of the branches beyond the nearest branch point, minimizing loss in the section to a predetermined upper limit.
