Abstract: A resin multilayer substrate includes a multilayer body including resin base-material layers laminated in a thickness direction and a circuit conductor therein, an end-surface ground conductor provided directly on each end surface of the multilayer body in the thickness direction, an adhesion layer on a side surface of the multilayer body, and a side-surface ground conductor on the adhesion layer. The end-surface and side-surface ground conductors are made of a ground conductor material with a coefficient of thermal expansion whose difference from a coefficient of thermal expansion of the resin base-material layers in a plane direction is smaller than a difference from a coefficient of thermal expansion of the resin base-material layers in the thickness direction. The adhesion layer is made of a material with higher adhesiveness to the side surface of the multilayer body than adhesiveness of the ground conductor material.

CPC classification number: H01Q21/065 , H01Q9/045
Abstract: An antenna module includes an antenna substrate and a feed circuit. The antenna substrate has an upper surface and a lower surface, and a radiating element having a flat plate shape is arranged in the antenna substrate. The feed circuit 105 is mounted on the lower surface of the antenna substrate and supplies a radio frequency signal to the radiating element. The antenna substrate includes a dielectric substrate on which the radiating element is arranged, a ground electrode, a feed wiring, and carbides. The ground electrode is arranged between the radiating element and the lower surface in the dielectric substrate. The feed wiring transmits the radio frequency signal supplied from the feed circuit to the radiating element. The carbides are disposed on at least a part of a side surface connecting the upper surface and the lower surface in the dielectric substrate.

Abstract: A substrate bonding structure includes a first substrate including a first resin substrate that melts by heating, a second substrate having a second resin substrate that melts by heating, and an overlapping portion with the first substrate. The overlapping portion between the first substrate and the second substrate includes a hole continuously extending from the first substrate to the second substrate. The first substrate includes a melted portion of the first resin substrate around the hole, and the second substrate includes a melted portion of the second resin substrate around the hole. The first substrate and the second substrate are bonded to each other with a fused portion between the melted portion of the first resin substrate and the melted of the second resin substrate.
