| Number | Title | Issue Date |
| 8330563 | High-frequency member assembly with waveguide A high-frequency member assembly has two high-frequency members of which surfaces are attached to each other. Each member has a rectangular waveguide hole penetrating through the member and two choke grooves opened on the attaching surface. The waveguide holes commu... | 12/11/2012 |
| 8314742 | Antenna device with lens or passive element acting as lens An antenna device has a divider producing first and second signals, and amplifiers amplifying the signals at a changeable amplitude ratio of the first signal to the second signal. A Rotman lens gives first phase differences to first high frequency waves, produced fr... | 11/20/2012 |
| 8134427 | Waveguide tube formed by laminating a plate and substrates having waveguide passages There are provided a waveguide plate that is made of metallic plates through which through holes are formed and a pair of resin made substrates (first and second substrates) on which a grounding pattern is formed to cover the through holes. Both the waveguide plate ... | 03/13/2012 |
| 8054142 | Plural rectangular waveguides having longer cross-sectional lengths based on shorter waveguide line lengths Long-side length a1 to a5 of rectangular waveguide tubes in a long-side direction (magnetic field direction) become greater, the shorter a line length is (the closer a rectangular waveguide tube is to the center). ai and Li are set such that line lengt... | 11/08/2011 |
| 7750755 | Transmission line transition A transmission line transition for coupling electromagnetic energy between different transmission lines includes first and second dielectric substrates laminated to each other and a waveguide tube attached to the first dielectric substrate. The laminated dielectric ... | 07/06/2010 |
| 7701310 | Dielectric substrate for wave guide tube and transmission line transition using the same A transmission line transition includes a waveguide tube section having a waveguide tube, a waveguide tube section that is formed of at least a dielectric substrate and a line transition section formed of at least a dielectric substrate disposed adjacent the wavegui... | 04/20/2010 |
| 7554418 | Waveguide/strip line converter having a multilayer substrate with short-circuiting patterns therein defining a waveguide passage of varying cross-sectional area A waveguide/strip line converter includes a waveguide and a multilayer substrate. A second end of the multilayer substrate is fixed to an opening of the waveguide. The multilayer substrate includes a plurality of dielectric layers to form a plurality of substrate fa... | 06/30/2009 |
