An antenna-integrated wireless module comprises a substrate having a first surface and including a wireless region and an antenna region. A wireless functional section is in the wireless region and includes an RF circuit on the first surface or in the substrate. An antenna section is in the antenna region and includes an antenna conductor. A resin sealing layer covers at least a part of the first surface. A thickness of the resin sealing layer in a portion overlapping the antenna region may be thinner than a thickness of the resin sealing layer in a portion overlapping the wireless region such that the resin sealing layer may have a step at a location between the wireless region and the antenna region; or the substrate may have a step at a boundary between the wireless region and the antenna region, and the resin sealing layer may not the cover the step.

Antenna-integrated wireless module and method for manufacturing antenna-integrated wireless module

An antenna-integrated wireless module is provided which does not need a metal case, and which can realize size reduction. A shield layer is formed on an upper surface of a resin sealing layer, which is disposed on one principal surface of a substrate and which covers a wireless region and an antenna region, such that the shield layer does not cover a portion of the resin sealing layer, the portion being positioned directly above the antenna region. Hence the shield layer formed on the upper surface of the resin sealing layer on the side covering the wireless region can serve to suppress electromagnetic waves radiated from a wireless functional section, which is disposed in a region overlapping the wireless region when looking at the module in a plan view, and which includes an RF circuit disposed at least on the one principal surface of the substrate or inside the substrate.

A wireless communication module includes a circuit board, and an antenna and a connection member mounted on a mounting surface of the circuit board. The antenna is mounted in a region along a first end edge of the circuit board, and the connection member is mounted in a region along a second end edge of the circuit board.

Composite module and electronic apparatus including the same

Circuit modules including identification codes and a method of managing them are provided. A module substrate includes signal input output terminals and outer ground terminals provided at the peripheral portions of a surface which becomes a mounting surface when the circuit module is completed. An inner-ground-terminal formation area surrounded by the signal input output terminals and the outer ground terminals includes a plurality of inner ground terminals arranged in a matrix of rows and columns. One of the edge portions is a direction identification area. The inner ground terminal is not provided in the direction identification area, and a first identification code having information about the position of the module substrate is provided in the direction identification area.
