摘要： PROBLEM TO BE SOLVED: To provide a compact and lightweight power divider capable of performing power distribution of a large-power microwave with high efficiency and suppressing a leak of electric power to the outside.
SOLUTION: The power divider as an embodiment of the presest invention has, especially, (1) an E surface size and an H surface size set to optimum values at a specified frequency. Consequently, characteristic impedance of the waveguide is matched with characteristic impedance of a microstrip line power-coupled with the waveguide. Further, the power divider has (2) a shield part arranged to form a closed space for an opening part of a slot. Consequently, electric power is prevented from leaking from the opening part of the slot provided to the waveguide to a space on a microstrip line mounted side to improve slot coupling efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a miniaturized and lightweight power distributor capable of highly efficiently distributing great-power microwaves.
SOLUTION: In a power distributor using waveguide slot coupling, the size of a waveguide is added to a design parameter, the dimension of the waveguide is changed from a conventional international standard dimension, and the characteristic impedance of a microstrip line is matched to the characteristic impedance of the waveguide. Thus, a power distributor having a 90% or a higher coupling degree over wide frequency bands can be obtained. Furthermore, a waveguide is used for a power input section, the power distributor is also capable of being sufficiently immune to great-power microwave inputs. Moreover, since only a substrate whose thickness is 1 mm or less is mounted with the waveguide size as the size of the power distributor, the power distributor can be small-sized and lightweight extremely.

摘要翻译：要解决的问题：提供能够高效分配大功率微波的小型化和轻量化的配电器。解决方案：在使用波导槽耦合的功率分配器中，波导的尺寸被添加到设计参数中，波导的尺寸从传统的国际标准尺寸改变，并且微带线的特性阻抗匹配到波导的特性阻抗。因此，可以获得在宽频带上具有90％或更高耦合度的功率分配器。此外，波导用于功率输入部分，功率分配器还能够充分地免受大功率微波输入的影响。此外，由于仅将厚度为1mm以下的基板安装为波导尺寸作为配电器的尺寸，因此功率分配器可以小型化和轻量化。版权所有（C）2006，JPO＆NCIPI
