Abstract: An antenna module includes a dielectric substrate having a multilayer structure, a ground electrode disposed in the dielectric substrate, a plate-like fed element facing the ground electrode and disposed at a layer different from a layer including the ground electrode, a feed line for transferring a radio-frequency signal to a feed point of the fed element, and a stub. The stub branches off from the feed line at a branch point of the feed line and has an open end. The stub is disposed between the fed element and the ground electrode. When the dielectric substrate is viewed in plan view, the open end coincides with the fed element.

Abstract: An antenna element includes a dielectric substrate, a radiation electrode, a first ground electrode, a second ground electrode, and a via conductor that connects the first ground electrode and the second ground electrode to each other. The dielectric substrate includes a flat-plate-shaped first part and a second part that is thinner than the first part. The radiation electrode and the first ground electrode are arranged on or in the first part so as to face each other in the thickness direction of the first part. The second ground electrode is spaced apart from the radiation electrode. The second ground electrode is arranged on or in the second part so as to not face the radiation electrode in the thickness direction of the second part. The radiation electrode is capacitively coupled to the second ground electrode and the via conductor.

Abstract: A multi-antenna module includes, on or in the dielectric substrate, a first radiation element, a second radiation element that operates at a frequency band lower than that of the first radiation element, and a ground plane. A first feed line and a second feed line are provided on or in the dielectric substrate. A first switch element switches between a first state in which a signal is supplied to the second radiation element and a second state including at least one of a state in which the second radiation element is connected to the ground plane with terminal impedance interposed therebetween, a state in which the second radiation element is in a floating state with respect to the second feed line and the ground plane, and a state in which the second radiation element is short-circuited to the ground plane.

Abstract: An antenna module includes a dielectric substrate having a multilayer structure, a power supply element and a ground electrode (GND) disposed in or on the dielectric substrate, a parasitic element, a power supply wiring line, and first and second stubs to be connected to the power supply wiring line. The parasitic element is disposed in a layer between the power supply element and the ground electrode (GND). The power supply wiring line passes through the parasitic element and supplies radio frequency power to the power supply element. The first stub is connected to a position different from a connection position of the second stub in the power supply wiring line.

Abstract: As such, in the disclosure, a slit is formed in a side plate. The slit has an opening in the upper end surface of the side plate. The opening has a width which is smaller than a thickness of the side plate and enables to correspond to a thickness t of the substrate and a length which enables to correspond to a length a of one side of the substrate. An RF antenna module is housed in the slit formed in the side plate of the housing to be accommodated in the housing by inserting the one side of the substrate through the opening of the slit, which is formed in the upper end surface of the side plate, and inserting the substrate into the slit by an amount equal to or larger than a length of another side of the substrate.

Abstract: In a multilayer substrate (2), an internal ground layer (11) is provided at a position between insulating layers (4) and (5) and a radiating element (13) is provided at a position between insulating layers (3) and (4). A first coplanar line (7) is connected to an intermediate position of the radiating element (13) in an X-axis direction, and a second coplanar line (9) is connected to an intermediate position of the radiating element (13) in a Y-axis direction. A passive element (16) is laminated on the upper surface of the radiating element (13) through the insulating layer (3). The passive element (16) is formed in a cross shape in which a first patch (16A) extending in the X-axis direction and a second patch (16B) extending in the Y-axis direction are orthogonal to each other.

Abstract: The antenna device includes multiple first radiation plates and multiple second radiation plates. Each of the first radiation plates has a first feed point and a first ground end portion, and radiates a first radio wave. Each of the second radiation plates has a second feed point and a second ground end portion, and radiates a radio wave of a frequency different from the frequency of the first, radio wave. When the antenna device is viewed in a direction orthogonal to the polarization direction of the first radio wave, the first radiation plate and the second radiation plate are disposed so as not to overlap.

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.

Abstract: An antenna device is enclosed in a housing. The antenna device includes a dielectric substrate in which a plurality of layers including a ground layer is stacked on top of one another, a feed element, a parasitic element, a feed line, and a conductive member placed in or on the dielectric substrate. The feed element is placed within or on a surface of the housing, and the parasitic element is placed in the dielectric substrate. The feed line is placed, in the dielectric substrate, in a layer between a layer in which the parasitic element is placed and the ground layer and sends a radio frequency signal. When the dielectric substrate is attached to the housing, the conductive member electrically connects the feed line and the feed element and supplies a radio frequency signal to the feed element.
