A wireless communication device includes: an antenna including an antenna element, and a ground conductor; an IC connected to the antenna; and a metal member arranged to face the antenna. The ground conductor includes one end and the other end in the X direction. The metal member includes a metal plate, and a projection protruding from the metal plate toward the antenna. The projection is arranged at a position of overlapping with the end of the ground conductor as viewed in the −Z direction. Such a configuration improves the transmission and reception gains at the communication frequency of a radio element.

An antenna apparatus includes a conductive radiating element, a conductive member, and a first impedance circuit. The first impedance circuit includes a first parallel resonant circuit (an LC parallel resonant circuit) and is directly connected between the radiating element and the conductive member (the conductor plate). Since the first parallel resonant circuit has high impedance in its resonant frequency band and is equivalently in an open state, one end of the radiating element is opened in the resonant frequency band. Accordingly, the radiating element defines and functions as a standing-wave antenna that contributes to electric-field radiation and a loop portion including the radiating element, the conductive member, and the first impedance circuit defines and functions as a magnetic-field radiation antenna that contributes to magnetic-field radiation.

A method comprises obtaining, at an antenna proximity sensing circuit on a circuit board, proximity sensing information indicative of proximity of a part of a human body to an antenna, the antenna electrically connected to the circuit board, and, in response to the obtaining, providing, to an antenna tuning circuit on the circuit board, a tuning parameter value to adapt antenna tuning for the proximity of the part of the human body to the antenna.

The TIC environmental event sensor is a nickel-sized, ultra-thin circuit assembly, containing an extremely compact array of both environmental sensors and physical sensors, along with local and wireless access to all the sensor data, including BTLE & LoRa, as well as an electronic ink display for limited field access to sensor events in real time. The TIC is designed to capture changes in the sensor data in real time, and then log it for future examination. The most recent change will remain on the device’s display. The changes can then be transmitted to a smart phone or tablet via BTLE, networked as an asset via LoRa, or locally scrolled at the device. The TIC is Ideal for tracking any variations in the surrounding conditions of an asset’s travel, storage, or use.
