Abstract: An antenna module includes a dielectric substrate including a plurality of dielectric layers that are laminated, and a radiation element, a ground electrode, and peripheral electrodes that are formed in or on the dielectric substrate. The radiation element radiates radio waves in a first polarization direction. The ground electrode is placed so as to face the radiation element. The peripheral electrodes are formed in a plurality of layers between the radiation element and the ground electrode and are electrically connected to the ground electrode. The peripheral electrodes are placed at positions that are symmetrical with respect to at least either of a first direction parallel to the first polarization direction and a second direction orthogonal to the first polarization direction.

Abstract: An antenna module including dielectric electrodes whose normal directions are different from each other, emitting elements and a ground electrode disposed on the dielectric substrate, and emitting elements disposed on the dielectric substrate. The emitting element is capable of emitting radio waves of a first frequency band. The emitting element is disposed adjacent to the emitting element and is capable of emitting radio waves of a second frequency band higher than the first frequency band. On the dielectric substrate, the emitting element is disposed at a position that is closer to the dielectric substrate than the emitting element is. The distance from the center of the emitting element to an end surface of the ground electrode that is closer to the dielectric substrate is shorter than the distance from the center of the emitting element to an end surface of the ground electrode that is farther from the dielectric substrate.

Abstract: An antenna module includes first and second dielectric substrates having different normal directions, and first and second radiating elements. The first radiating elements are disposed in the X-axis direction at the first dielectric substrate. The second radiating elements are disposed in the X-axis direction at the second dielectric substrate. The first radiating elements disposed in the X-axis direction are more than the second radiating elements disposed in the X-axis direction. The measurement perpendicular to the X-axis direction of the second dielectric substrate is shorter than the measurement perpendicular to the X-axis direction of the first dielectric substrate. The distance from a second radiating element closest to an end portion in the X-axis direction of the second dielectric substrate to the end portion is longer than the distance from a first radiating element closest to an end portion in the X-axis direction of the first dielectric substrate to the end portion.

Abstract: An antenna module includes a dielectric substrate, radiating circuits disposed on the dielectric substrate, a ground electrode, and a dielectric layer. In a plan view in a direction of a normal line of the dielectric substrate, the radiating circuit is disposed adjacent to the radiating circuit. The ground electrode is disposed to face the radiating circuit and the radiating circuit. The dielectric layer is disposed to cover the radiating circuit. The radiating circuit is capable of emitting an electric wave in a frequency band higher than that for the radiating circuit. A dielectric constant of the dielectric layer is higher than a dielectric constant of the dielectric substrate. A distance between the radiating circuit and the ground electrode is shorter than a distance between the radiating circuit and the ground electrode.

Abstract: An antenna device is formed by arranging radiation elements each radiating a circularly polarized wave in a matrix of three rows and four columns. The radiation elements include three sets of radiation elements of four types having a positional relationship rotationally symmetric with each other. The radiation elements are arranged such that adjacent elements are of different types.

Abstract: An antenna module includes a dielectric substrate, a radiation electrode, a ground electrode, and a current-interrupting element. The radiation electrode is disposed in a layer of the dielectric substrate, and the ground electrode is disposed in another layer of the dielectric substrate. The current-interrupting element is electrically connected to the ground electrode. The current-interrupting element is configured to interrupt a current flowing through the ground electrode. The current-interrupting element has a first edge portion electrically connected to the ground electrode and a second edge portion left open and includes a planar electrode parallel to the ground electrode. The dimension of the current-interrupting element in the direction from the first edge portion to the second edge portion is about λ/4, where λ is the wavelength of a radio-frequency signal radiated from the radiation electrode.

Abstract: An antenna module includes a radiation electrode in which a radio frequency signal is supplied to a first feed point and a second feed point. The antenna module further includes a feed wire configured to supply a radio frequency signal to the first feed point of the radiation electrode and a feed wire branching from the feed wire and configured to supply a radio frequency signal to the second feed point. The feed wire includes two paths connected in parallel between the first feed point and the second feed point and having the same length. The paths are disposed so as to be mutually line-symmetric in plan view of the antenna module with respect to a straight line connecting the first feed point to the second feed point.

Abstract: An antenna module includes a first antenna element disposed at a first dielectric substrate, a second antenna element disposed at a second dielectric substrate, a joint connecting the first dielectric substrate and the second dielectric substrate, and a power supply line. The second dielectric substrate is different from the first dielectric substrate with respect to the normal direction. The power supply line extends from the first dielectric substrate via the joint to the second antenna element and is configured to communicate a radio-frequency signal to the second antenna element. At least a part of the power supply line at the joint is formed in a direction crossing the polarization plane of radio waves radiated by the first antenna element and the second antenna element.
