Abstract: The first conductor plate has a groove portion that has a rectangular cross section and is formed in parallel with a first main surface such that the longitudinal direction becomes a first direction, and a first vertical tube portion formed in a direction away from the second conductor plate in a second direction orthogonal to the first direction and the first main surface, with a branch position in the groove as a starting point. The second conductor plate includes a reflection portion that is inserted into the groove portion in a manner protruding from a second main surface, which is a flat surface of the second conductor plate in contact with the first main surface, and has a reflection surface that reflects the radio wave, propagated along the groove portion, toward the first vertical tube portion.

Abstract: A terminal network apparatus performs wireless communication with a user terminal apparatus. The terminal network apparatus receives a registration request which is transmitted from the user terminal apparatus, and assigns a node name to the user terminal apparatus. The terminal network apparatus receives a reregistration request from a user terminal apparatus which has moved from a wireless service area of another terminal network apparatus, and assigns a new node name to the user terminal apparatus. The terminal network apparatus transmits a notification that includes an old node name and the new node name to the terminal network apparatus that had assigned the old node name. When the terminal network apparatus receives the notification, the terminal network apparatus generates an entry, in which the old node name and the new node name are correlated, in a node name pair table.
