Abstract: In a multilayer substrate, first interlayer connection conductors pass through resin layers in a lamination direction and electrically connect first and second signal conductors. Second interlayer connection conductors pass through the resin layers in the lamination direction and electrically connect the first and second signal conductors. The first interlayer connection conductors are aligned in a first row extending along the first signal conductor when viewed in the lamination direction. The second interlayer connection conductors are aligned in a second row extending along the first signal conductor when viewed in the lamination direction. A direction perpendicular to the direction in which the first signal conductor extends, when viewed in the lamination direction, is a line width direction. A position of the second row in the line width direction is different from a position of the first row in the line width direction.

Abstract: A semiconductor component is face-up mounted on a package substrate. An antenna substrate is flip-chip mounted on a front side of the semiconductor component. A device-side high-frequency signal terminal is disposed on the front side of the semiconductor component, and an antenna-side high-frequency signal terminal is disposed on a back side of the antenna substrate. The device-side high-frequency signal terminal and the antenna-side high-frequency signal terminal are electrically connected to each other. Thus, the antenna substrate for high-frequency signals can be separated from the package substrate for baseband signals.

Abstract: A multilayer substrate includes a stacked body of insulating base material layers and conductor patterns on the insulating base material layers. A thickness adjustment base material layer includes a frame portion, an opening portion inside the frame portion, and an island shaped portion inside the frame portion, and connection portions to connect the island shaped portion to the frame portion. The conductor patterns, in a stacking direction of the insulating base material layers, are wound around the island shaped portion. A line width of the connection portions is smaller than the width of the island shaped portion connected to the frame portion through the connection portions. An area overlapped with the conductor patterns is larger in the opening portion than in the frame portion and the island shaped portion.

Abstract: An antenna element includes a body including laminated insulator layers, a first ground conductor, and a radiation conductor overlapping the first ground conductor along a first direction from the first ground conductor. Guard ground conductors are provided in the body along the first direction to surround the radiation conductor. The guard ground conductors include second ground conductors electrically interconnected, and one or more first interlayer connection conductors piercing the insulator layers. The second ground conductors are shaped to not make a circuit of the radiation conductor, and are positioned at multiple positions relative to up-down directions. The second ground conductors each have an overlapping portion that overlaps the second ground conductor positioned adjacent to the overlapping portion in an upward or downward direction, and a non-overlapping portion that does not overlap the second ground conductor positioned adjacent to the non-overlapping portion in the upward or downward direction.

Abstract: A multilayer resin substrate includes a base material including stacked resin layers including an opening resin layer, a conductor pattern, and an interlayer connection conductor. A concave portion is provided in the base material. The opening resin layer is closer to a first main surface than other resin layers. The concave portion includes a first opening portion provided by a cutting process from one surface of the opening resin layer, and another resin layer. The interlayer connection conductor is provided by filling a conductor in a second opening portion provided by a cutting process from an opposite surface of the opening resin layer. The end portion of the one surface of the first opening portion is not in contact with the conductor pattern.

Abstract: A multilayer substrate includes a stacked body, coil conductor patterns, and a connection conductor pattern. The stacked body includes insulating layers. A first coil conductor pattern is provided on the front surface of an insulating layer and has a wound shape including outer and inner end portions. A second coil conductor pattern is provided on the front surface of the insulating layer and includes an end portion. The connection conductor pattern is provided in the stacked body, and connects the coil conductor patterns. The outer end portion is connected to a terminal conductor on a back surface of the stacked body. The end portion of the second coil conductor pattern is connected to the terminal conductor on the back surface of the stacked body. The first coil conductor pattern extends parallel or substantially parallel to the second coil conductor pattern along an outer periphery of the second coil conductor pattern.

Abstract: A transmission line portion of a flat cable that is bent at a position along the longitudinal direction includes a dielectric element body, a first ground conductor, and a second ground conductor. The dielectric element body includes a signal conductor at the middle position of the thickness direction. The first ground conductor includes elongated conductors and bridge conductors. The elongated conductors are spaced in the width direction of the dielectric element body, and extend in the longitudinal direction. The bridge conductors connect the elongated conductors at spacings along the longitudinal direction. The spacing of bridge conductors across the bending point in a bent portion is smaller than the spacing of adjacent bridge conductors located in a straight portion.
