Abstract: A dielectric block includes a bottom surface that includes a conductive ground member including an antenna ground surface inclined with respect to the bottom surface. A feed element is disposed at a distance from the antenna ground surface, and constitutes a patch antenna together with the antenna ground surface. A feed line is connected to a feed point of the feed element, and a dielectric member that supports the feed element with respect to the ground member. The ground member is exposed to the bottom surface, on both a lower side and a higher side of a contour line passing through an intersection point of a perpendicular line from the feed point to a virtual plane including the bottom surface and a plane including the antenna ground surface, using the bottom surface as a height reference.

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

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: Provided is an array antenna in which a plurality of sub-arrays, which each include a plurality of radiating elements, are two-dimensionally arranged in a first direction and a second direction, which are perpendicular to each other. A plurality of power feeding lines individually feed power from a high-frequency input/output device to each of the plurality of sub-arrays. The plurality of sub-arrays are arranged along straight lines in the first direction, and are arranged in the second direction such that among two sub-arrays that are adjacent to each other in the second direction, one sub-array is shifted in the first direction with respect to the other sub-array.

Abstract: An antenna module includes a mounting board with a flat plate shape, and a power supply circuit to supply a radio frequency signal. The power supply circuit is mounted on the mounting board, and a radiating electrode is arranged on the power supply circuit. A dielectric fills a region around the power supply circuit and the radiating electrode. A conductive layer covers at least part of the dielectric. In the dielectric, a lens part is formed at a position overlapping the radiating electrode in plan view of the mounting board. The dielectric includes a first region in which the lens part is formed and a second region other than the first region, and the conductive layer is formed in the second region.

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: An antenna module includes a dielectric layer in a form of a flat plate, a ground electrode, a radiating element, and a wiring cable. The ground electrode is arranged on a lower surface of the dielectric layer. The radiating element is arranged on an upper surface of the dielectric layer as being opposed to the ground electrode. The wiring cable faces a side surface of the dielectric layer, and includes a ground electrode and a power feeder line that conveys a radio frequency signal to the radiating element. The wiring cable is smaller in thickness than the dielectric layer. The power feeder line and the ground electrode are electrically connected to the radiating element and the ground electrode, respectively. The ground electrode is arranged at a position different from a position of the ground electrode in a direction of thickness of the dielectric layer.
