Abstract: An antenna module includes an antenna substrate and a feed circuit. The antenna substrate has an upper surface and a lower surface, and a radiating element having a flat plate shape is arranged in the antenna substrate. The feed circuit 105 is mounted on the lower surface of the antenna substrate and supplies a radio frequency signal to the radiating element. The antenna substrate includes a dielectric substrate on which the radiating element is arranged, a ground electrode, a feed wiring, and carbides. The ground electrode is arranged between the radiating element and the lower surface in the dielectric substrate. The feed wiring transmits the radio frequency signal supplied from the feed circuit to the radiating element. The carbides are disposed on at least a part of a side surface connecting the upper surface and the lower surface in the dielectric substrate.

Abstract: A multilayer substrate in which dielectric layers are laminated, the multilayer substrate including: a first electrode formed on the dielectric layers; and a first ground electrode disposed so as to be opposite to the first electrode in a multilayer direction. In the multilayer substrate, a plurality of dielectric layers include a first layer and a second layer that are disposed between a layer in which the first electrode is formed and a layer in which the first ground electrode is formed. In the first layer, a filler having permittivity lower than permittivity of a base material forming the dielectric layer is not disposed. In the second layer, the filler is disposed in at least a part of a region where the first electrode and the first ground electrode overlap each other in planar view of the multilayer substrate from the multilayer direction.

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 includes a plurality of antenna devices. Each of the plurality of antenna devices includes a dielectric substrate on which an antenna element is placed and a feed line that transmits a radio frequency signal from a RFIC to the antenna element. The feed line is divided within the dielectric substrate and transmits a radio frequency signal to a feed point (122A-1) and a feed point (122A-2) of the antenna element, a phase of the radio frequency signal to the feed point (122A-1) and a phase of the radio frequency signal to the feed point (122A-2) being substantially opposite to one another.

Abstract: A first radiating element and a second radiating element each have a first extending portion protruding from a region where a ground conductor is formed to a non-ground-conductor region, and a second extending portion extending parallel with a boundary of the ground-conductor region and the non-ground-conductor region. The first radiating element and the second radiating element are arranged such that an open end of the second extending portion of the first radiating element and an open end of a second extending portion of the second radiating element face each other. A parasitic element is formed on a side of the second radiating element distant from the region (where the ground conductor is formed. A parasitic element is formed along the first radiating element. With this configuration, an antenna device is realized which has gain in two frequency bands and has forward directivity.

Abstract: An antenna module includes antenna groups, hybrid couplers, dividers, and an RFIC. The antenna group includes radiating elements. The antenna group includes radiating elements. Each hybrid coupler has input terminals and output terminals. The RFIC supplies a high frequency signal to each radiating element. Each divider splits the high frequency signal from the RFIC in two directions. The divider splits a first signal from the RFIC to the input terminal of each hybrid coupler. The divider splits a second signal from the RFIC to the input terminal of each hybrid coupler. The output terminals of the hybrid coupler are respectively connected to the radiating elements. The output terminals of the hybrid coupler are respectively connected to the radiating elements. In each hybrid coupler, a phase difference between the high frequency signals supplied to the input terminals is set to 90°.
