Latest Patents

Igarashi's latest patents include a two-port triplate-line/waveguide converter featuring two probes with tips extending in different directions. This invention provides a rectangular waveguide with 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 notable patent involves a feed line comprised of a triplate line that connects a waveguide/triplate-line converter to multiple patch antennas. The design ensures that the width and length of the feed line section directly match the parallel combination of the impedances of branches beyond the branch point, maintaining loss within a predetermined upper limit.
