Abstract: In an antenna array of the present disclosure, in a plan view from a direction that is normal to an isolation element, the isolation element is formed between a first antenna element and a second antenna element. A first distance between the first antenna element and a first ground electrode is different from a second distance between the isolation element and the first ground electrode. A third distance between the second antenna element and the first ground electrode is different from the second distance. In a plan view from a direction that is normal to the first antenna element, the isolation element is spaced apart from the first antenna element. In a plan view from a direction that is normal to the second antenna element, the isolation element is spaced apart from the second antenna element.

Abstract: A patch antenna includes a ground conductor pattern, feeding conductor patterns (11, 12), and a feed line (15). The feeding conductor patterns (11, 12) are disposed on the same side with respect to the ground conductor pattern and are of different sizes.

The feeding conductor pattern (12) has a feed point (121) for direct feeding through the feed line and a feed point (122) for capacitive feeding through the feed line. The feed points (111, 112) are opposite to each other with respect to a center point of the feeding conductor pattern (11).

Abstract: An irreversible circuit element includes first and second high pass isolators each including first and second center electrodes intersecting with and being insulated from each other on a ferrite to which a direct-current magnetic field is applied with a permanent magnet. One end of the first center electrode is an output port and the other end thereof is an input port, and one end of the second center electrode is another output port and the other end thereof is a ground port. A pass frequency band of the first isolator is higher than a pass frequency band of the second isolator. Respective output portions of the first and second isolators are electrically connected and defined as one output terminal, and a low pass filter LPF is inserted between the output terminal and the output port of the second isolator.

Abstract: An antenna module includes a dielectric substrate including a plurality of laminated dielectric layers, a radiating element, a ground electrode, and a peripheral electrode. The ground electrode opposes the radiating element. The peripheral electrode is on a layer between the radiating element and the ground electrode and electrically connected to the ground electrode. The radiating element radiates a radio wave in a first polarization direction. A dimension of the ground electrode in the first polarization direction is shorter than a dimension of the ground electrode in a specific direction orthogonal to the first polarization direction. When the dielectric substrate is seen in plan view in a layered direction, at least a portion of the peripheral electrode is disposed between an end portion of the ground electrode and an end portion of the radiating element in the first polarization direction.

Abstract: An antenna module includes a dielectric substrate and a radiation element disposed on the dielectric substrate. The dielectric substrate includes a flat portion (131) and a flat portion (130) having mutually different normal directions, and a bent portion connecting the flat portion (131) and the flat portion (130) to each other. The flat portion (131) has a protruding portion partially protruding in a direction toward the flat portion (130) along the flat portion (131) from a boundary portion between the bent portion and the flat portion (131). The flat portion (131) and the bent portion are connected to each other at a position where the protruding portion is not provided in the flat portion (131). At least a part of the radiation element is disposed on the protruding portion.

Abstract: A flexible substrate includes a dielectric having flexibility, a first line, a second line, and ground electrode. The dielectric has a first surface and a second surface opposed to the first surface. The first line , the ground electrode, and the second line are laminated in this order in layers from the first surface to the second surface. When the flexible substrate is seen through from the thickness direction of the flexible substrate, the first line has a line-symmetrical portion that is line-symmetrical with respect to the second line with a virtual intermediate line (LM) serving as a symmetric line.

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.
