An antenna device includes: a dielectric substrate having a feed line and a radiation unit provided on a first surface and having a ground conductor provided on a second surface opposite to the first surface; and a pair of second slits that is provided on a side of the radiation unit facing a side to which the feed line is connected and expands in directions away from each other toward the side to which the feed line is connected when the first surface is viewed from above.

Antenna device and array antenna device

This antenna device is provided with: a ground; strip lines that extend from positions facing each other with respect to the width direction of the ground; a plurality of slots which is provided to the ground and which intersects with straight lines along the strip lines; and branch lines which intersect with the slots that are positioned to face the branch lines in a back surface.

Antenna device and array antenna

Substrate for antenna device

In radiation elements, recessed portions for adjusting the power of an electromagnetic wave that passes through the radiation elements are formed as power adjustment portions at coupling portions, respectively, which are on the opposite side of a feeding unit out of sets of two coupling portions to a feed line.

Antenna device

A square waveguide () has four ridges (). The cross section of the square waveguide () perpendicular to a waveguide axial direction is square. Inside the square waveguide (), two rectangular waveguide terminals () are formed by partitioning the inside along the waveguide axial direction. A septum phase plate () formed to get narrower stepwisely as its gets closer to a square waveguide terminal () opposite to the rectangular waveguide terminals () is provided. A projecting portion () is provided on a part of a ridge () formed on a ridge-side wall surface opposite to a wall surface, the septum phase plate () being joined to the wall surface in a part where the septum phase plate has largest width, the projecting portion () being larger than other parts of the ridge () in a cross-sectional shape perpendicular to the waveguide axial direction.

Polarization separation circuit

Disclosed is an antenna device including a rectangular waveguide () having a first opening end () and a second opening end (), a septum phase plate () disposed inside the rectangular waveguide () in such a way as to partition the first opening end () into two parts along a first direction perpendicular to a waveguide axial direction of the rectangular waveguide (), a width of the septum phase plate in a second direction perpendicular to both the waveguide axial direction of the rectangular waveguide () and the first direction becoming narrower stepwise with advancing from the first opening end () toward the second opening end (), and first projecting portions () disposed on two respective first inner walls () parallel to the septum phase plate (), out of four inner walls of the rectangular waveguide (), in such a way as to project toward an inside of the rectangular waveguide ().

An array antenna device, including: a waveguide () having a plurality of radiation units () arranged on one tube wall thereof, in which the waveguide () has a plurality of grooves () arranged on an inner side of a tube wall facing the tube wall, movable short-circuit surfaces () each electrically short-circuited to an inner wall of one of the grooves (), and movable short-circuit surface controlling mechanisms () for changing positions of the movable short-circuit surfaces ().

Array antenna device

A ground conductor () having slots (to) for radiating electromagnetic waves, a ground conductor () in which cavities () recessed in a direction away from the ground conductor () is formed in positions opposite to the slots (to) of the grounding conductor (), and central conductors (to, and) arranged in positions overlapping with the slots (to), respectively, between the ground conductor () and the ground conductor () are provided. The central conductors (to, and) are arranged such that the ground conductor () is closer to them than the ground conductor ().

[Object] To provide a device assisting a user to easily generate, in relation to an issue of interest to the user, a question sentence guaranteed to have an answer of a certain accuracy or higher in a question-answering system. [Solution] A question sentence generating device is used with a question-answering system, and it includes: word receiving means for receiving a wordas a source for generating a question sentence; and question sentence generating databasecomprised of a plurality of entries for generating a question sentence. Each of the plurality of entries has a word as a key and includes an answer sentence pattern co-occurring with the word, used in the question-answering system. The question sentence generating device further includes a question sentence generating unit, searching the question sentence generating databasefor an answer sentence pattern using the wordreceived by the word receiving means as a key, for generating a question sentence from a retrieved answer sentence pattern and the received word
