Abstract: This waveguide comprises: three or more conductor layers that are stacked; two or more dielectric layers that are stacked, each being formed between two conductor layers adjacent to each other among the three or more conductor layers; and a first via group and a second via group each including one or more vias disposed in at least one dielectric layer among the two or more dielectric layers. The first via group and the second via group are arrayed in parallel. Among the vias included in the first via group and the second via group, the vias disposed in at least one of the two or more dielectric layers differ in position on the plane of the dielectric layer from the vias disposed in the remaining dielectric layer.

Abstract: In a radio network system containing a first radio apparatus that performs central control and a second radio apparatus, the second radio apparatus receives a first signal containing first identification information indicating a transmission source during a first reception period, receives a second signal containing second identification information indicating a transmission source during a second reception period, measures first reception information on reception of the first signal, measures second reception information on reception of the second signal, and transmits first measurement information containing the first reception information and the first identification information and second measurement information containing the second reception information and the second identification information to the first radio apparatus. When the first identification information and the second identification information are the same, the first radio apparatus compares the first reception information and the second reception information to determine whether a radio apparatus in an abnormal condition is present.

Abstract: A transmission device transmits multiplexed signals obtained by multiplexing signals of N systems corresponding to N Orbital Angular Momentum (OAM) propagation modes. The transmission device includes: an array antenna that includes M antenna elements disposed in a lattice on a plane when viewed from the plane; and a transmitter that multiplies signals obtained by branching each of the signals of N systems into M signals by weighting coefficients of phase shift angles based on angles of the respective M antenna elements with respect to a reference axis passing through a reference point viewed from the reference point on the plane according to the OAM propagation modes, multiplexes the signals of N systems multiplied by the weighting coefficients of the phase shift angles, and transmits signals obtained by the multiplexing from the M antenna elements. M and N are integers equal to or larger than 2.

Abstract: This waveguide comprises: a first multilayered board in which a first dielectric layer and a plurality of first conductive layers the latter of which has a first opening are stacked; a first through via group in which a plurality of first through vias for electrically connecting the first conductive layers are aligned, in an in-plane direction of the first multilayered board, at intervals that are equal to or less than the one-half wavelength of an electromagnetic wave that is to be caused to propagate through the waveguide; and a second through via group in which a plurality of second through vias for electrically connecting the first conductive layers are aligned at said intervals in the in-plane direction. The waveguide does not have any through vias other than the plurality of first through vias and the plurality of second through vias. The first through via group and the second through via group are arranged, in the in-plane direction, in a direction orthogonal to the direction of the electric field of signals propagating in the thickness direction of the first multilayered board and are opposed to each other with the first opening therebetween.
