Abstract
An antenna device is configured to include: a divider circuit including an input/output terminal and a plurality of divider terminals; a plurality of matching circuits including one ends connected with the divider terminals; and a plurality of antenna elements connected with other ends of the matching circuits. Furthermore, the matching circuits are lossless circuits each having only an inductance component and a capacitance component, and the divider circuit is a lossless circuit whose characteristic impedance is indicated only by the inductance component and the capacitance component.

An antenna device comprising:
- a divider circuit including an input/output terminal and a plurality of divider terminals;
- a plurality of matching circuits respectively having one ends connected with the plurality of divider terminals, respectively;
- and
- a plurality of antenna elements respectively connected with other ends of the plurality of matching circuits, wherein
- each of the plurality of matching circuits is a lossless circuit having only an inductance component and a capacitance component, and
- the divider circuit is a lossless circuit whose characteristic impedance is indicated only by the inductance component and the capacitance component,
- wherein, assuming that a multiplication result is a corrected amplitude phase, the multiplication result being a multiplication result of a ratio of a signal to be given from each of the divider terminals to each of the plurality of matching circuits with respect to a signal to be given from each of the plurality of matching circuits to each of the plurality of antenna elements, and a desired amplitude phase of a signal to be given to each of the plurality of antenna elements,
- the divider circuit adjusts an amplitude phase of the signal to be given to each of the plurality of matching circuits in such a way that an amplitude phase of the signal to be given from each of the divider terminals to each of the plurality of matching circuits becomes the corrected amplitude phase.
