Abstract: An antenna module (100) includes a dielectric substrate (130) having a multilayer structure, a first radiating electrode (121) and a ground electrode (GND) that are disposed in the dielectric substrate (130), and a second radiating electrode (150) disposed in a layer between the first radiating electrode (121) and the ground electrode (GND). The first radiating electrode (121) is a power feed element to which radio frequency power is supplied. When the antenna module (100) is viewed in plan from a normal direction of the dielectric substrate (130), the first radiating electrode (121) and the second radiating electrode (150) at least partially overlap with each other. A thickness of the second radiating electrode (150) is larger than that of the first radiating electrode (121).

Abstract: An antenna device includes a ground electrode, a feed element, and a parasitic element. The ground electrode has a substantially non-square rectangular plane shape that includes a first side extending in a first direction and a second side extending in a second direction orthogonal to the first direction. The feed element has a substantially rectangular plane shape and is formed in such a way that each side of the feed element becomes parallel to the first direction or the second direction. The parasitic element is formed in such a manner as to face a side of the feed element parallel to the first side. The feed element is configured to radiate a first polarized wave that excites in the first direction and a second polarized wave that excites in the second direction. The length of the first side is longer than the length of the second side.

Abstract: First and second end-fire antennas are arranged on a dielectric substrate. The first end-fire antenna has polarization characteristics being parallel with a first direction. The second end-fire antenna has polarization characteristics being parallel with a second direction orthogonal to the first direction. A patch antenna provided with a first feed point and a second feed point, which are different from each other, is arranged on the dielectric substrate. When the patch antenna is fed from the first feed point, a radio wave whose polarization direction is parallel with the first direction is excited. When the patch antenna is fed from the second feed point, a radio wave whose polarization direction is orthogonal to the first direction is excited. A wireless communication module capable of achieving directivity in a wide range from a direction parallel with the substrate to the direction of the normal to the substrate is provided.

Abstract: A ground layer is disposed within a dielectric substrate. An antenna pattern that operates as an antenna is disposed so as to be closer to a first surface of the dielectric substrate than the ground layer is. A high-frequency device that supplies a high-frequency signal to the antenna pattern is mounted in or on a second surface of the dielectric substrate, which is opposite to the first surface. A plurality of signal conductor columns and a plurality of ground conductor columns that are made of a conductive material project from the second surface. Each of the signal conductor columns is connected to the high-frequency device by a wiring pattern, which is provided in or on the dielectric substrate, and the ground conductor columns are connected to the ground layer.

Abstract: Two high frequency antennas are provided in a multilayer substrate. Each high frequency antenna is configured of a radiation element, a high frequency power supply line, and a high frequency power supply unit. A low frequency antenna is configured of a series radiation element, a low frequency power supply line, and a lower frequency power supply unit. The series radiation element is formed of two radiation elements connected by a radiation element connection line. One end side of the series radiation element is connected to the low frequency power supply unit via the low frequency power supply line. Open stubs to block transmission of a high frequency signal (SH) are connected to the radiation element connection line and the low frequency power supply line. Short stubs to block transmission of a low frequency signal (SL) are connected to the high frequency power supply lines.

Abstract: An antenna module includes a dielectric substrate, in or on which a feed element is formed, a dielectric substrate, in which a ground electrode (GND) is formed, and conductive members. The dielectric substrate is disposed opposite the dielectric substrate. When viewed in plan in the direction normal to the feed element, the conductive members are disposed around the feed element. An air layer is formed between the dielectric substrate and the dielectric substrate. The conductive members are formed in the air layer.

Abstract: An antenna module includes feed elements each having a flat plate shape and a ground electrode arranged opposite the feed elements. The feed element radiates a radio wave of a first frequency band. The feed element radiates a radio wave of a second frequency band that is higher than the first frequency band. In a plan view of the feed element, the distance from the center of the feed element to an end portion of the ground electrode in a first direction is shorter than or equal to ½ of a free space wavelength of a radio wave radiated from the feed element. A feed point of the feed element is arranged at a location shifted in a second direction from the center of the feed element, and the second direction is different from the first direction.
