An antenna () includes a grounded conductive foil () disposed on a module substrate (), a first conductive foil (), and a second conductive foil (). The first conductive foil () and the second conductive foil () are disposed on the module substrate (), are elongated, and do not overlap with the grounded conductive foil () in a plan view of the module substrate (). The first conductive foil () has one end supplied with an antenna signal and the other end that is open. The second conductive foil () has one end connected to the grounded conductive foil () and the other end that is open. A wireless module () includes a circuit unit () including a communication circuit and provided to the module substrate () on which the antenna () is formed.

Antenna and wireless module

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

A liquid analyzer is one that performs analysis in a state of being immersed in a flowing analysis target liquid, and in order to simply make a good/bad determination and increase reliability, includes: a sensor adapted to, in a state where a responsive membrane is immersed in the flowing analysis target liquid, sense a predetermined component contained in the analysis target liquid; an analysis mechanism adapted to analyze the analysis target liquid with use of voltage generated in the sensor; and a resistance measurement mechanism adapted to, in the state where the responsive membrane is immersed in the flowing analysis target liquid, apply DC voltage to the responsive membrane to measure the resistance of the responsive membrane.

Liquid analyzer and liquid analysis system

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.

To measure target component concentration in a liquid with higher accuracy without any dedicated apparatus or skill, a method is adapted to include: receiving a successive measurement value obtained by performing successive measurement of the target component concentration with use of a first measurement device immersed in the liquid; receiving a batch measurement value obtained by, with use of a second measurement device, performing batch measurement of the target component concentration in a part sampled from the liquid; and, when the batch measurement value is received, successively calculating a correlation value indicating the correlation between multiple successive measurement values and multiple batch measurement values respectively obtained in mutually corresponding multiple times of successive measurement and multiple times of batch measurement. In addition, the first measurement device is adapted to calculate the target component concentration or correct a successive measurement value with use of the latest correlation value.
