摘要： A dielectric body includes a first radiating element on a first side and a second radiating element on a second side. The first radiating element and the second radiating element are linear conductors that each extend from a first end to a second end (an open end), and are parallel or substantially parallel to each other in a direction from the first end to the second end. The first end of the first radiating element is connected to a first port of a coupling degree adjustment circuit, and the first end of the second radiating element is connected to a second port of the coupling degree adjustment circuit. The first radiating element and the second radiating element are mainly coupled to each other in the coupling degree adjustment circuit.

摘要： A radiating electrode is disposed with a space from a ground conductor plate included in a substrate, in a thickness direction of the substrate. A dielectric member is loaded on the radiating electrode. The dielectric member includes two dielectric block portions disposed with a distance in an excitation direction of the radiating electrode. The two dielectric block portions are disposed across a geometric center of the radiating electrode in plan view, and, in plan view, a portion of each of the two dielectric block portions overlaps a portion of the radiating electrode and a remaining portion of each of the two dielectric block portions is disposed outside the radiating electrode.

The first inductance element and the second inductance element are wound and connected such that magnetic fields are mutually strengthened for one of the even mode and the odd mode, and such that the magnetic fields are mutually weakened for the other of the even mode and the odd mode.

摘要： An antenna device includes a substrate, a first ground layer, a radiation electrode, and waveguide structures. Each of the waveguide structures has a slit and a conductor wall. The slit is positioned in an electric field direction of the radiation electrode and provided in the first ground layer. The conductor wall surrounds the slit and extends in a thickness direction of the substrate. A dimension of the waveguide structure in a magnetic field direction in plan view is greater than ½ of a wavelength of a radio wave emitted by the radiation electrode in a medium of the substrate. A length from the slit to a terminal portion of the waveguide structure is about ¼ of a wavelength of the radio wave emitted by the radiation electrode in the waveguide structure.

摘要： An antenna apparatus includes a conductive radiating element, a conductive member, and a first impedance circuit. The first impedance circuit includes a first parallel resonant circuit (an LC parallel resonant circuit) and is directly connected between the radiating element and the conductive member (the conductor plate). Since the first parallel resonant circuit has high impedance in its resonant frequency band and is equivalently in an open state, one end of the radiating element is opened in the resonant frequency band. Accordingly, the radiating element defines and functions as a standing-wave antenna that contributes to electric-field radiation and a loop portion including the radiating element, the conductive member, and the first impedance circuit defines and functions as a magnetic-field radiation antenna that contributes to magnetic-field radiation.

摘要： A phase shifter includes a transformer connected between a first port and a second port and including a first coil and a second coil that is magnetically coupled to the first coil, the transformer including a parasitic inductance component; and an impedance adjustment circuit including a reactance element that suppresses a deviation in impedance due to the parasitic inductance component of the transformer. A coupling coefficient between the first coil and the second coil of the transformer and a value of the reactance element of the impedance adjustment circuit are determined such that a phase-shift amount changes in accordance with a frequency band.

摘要： To design an impedance transformation circuit, a transformer ratio of a transformer circuit is determined according to an impedance ratio. A coupling coefficient between a first inductance element and a second inductance element, an inductance of the first inductance element, and an inductance of the second inductance element are determined. A shape of the second inductance element is determined. A shape of the first inductance element is determined such that the first inductance element includes at least two layers of loop conductors, and an interlayer distance between the loop conductors is determined such that an inductance value of the first inductance element is a desired value.
