Disclosed embodiments can pertain to process indicator enhancements. A process indicator can include a dye material that has electrical properties such as conductivity and capacitance that can be employed to determine whether observed conditions are acceptable or not to sterilize medical equipment. Furthermore, the indicators can employ amplification, a specialized antenna, or both to allow signals, such as an electronic property value, to be communicated through sterilization containers that can shield or degrade signals. A number and location of indicators can also be determined and utilized to assist in visual inspection of the indicators as well as automatic evaluation.

A mobile terminal and an antenna that includes a feeder and a radiating element. The radiating element includes a first radiating patch and a second radiating patch. The first radiating patch and the second radiating patch are located on one side of the feeder and form a loop together with the feeder. An adjustable component configured to control the feeder and the second radiating patch is disposed on the feeder between the first radiating patch and the second radiating patch. The first radiating patch has a first extension part extending to an opposing side of the feeder.

An example method performed by a wireless-power-transmitting device that includes an antenna array is provided. The method includes radiating electromagnetic waves that form a maximum power level at a first distance away from the antenna array. Moreover, a power level of the radiated electromagnetic waves decreases, relative to the maximum power level, by at least a predefined amount at a predefined radial distance away from the maximum power level. In some embodiments, the method also includes detecting a location of a wireless-power-receiving device, whereby the location of the wireless-power-receiving device is further from the antenna array than a location of the maximum power level.

Proposed is an antenna module for a small device, wherein the antenna module is expanded to a ground area through a metal plate, a metal wire, or a connector FPCB and the like to improve antenna gain. The proposed antenna module for a small device is provided with an antenna, and comprises: a circuit board mounted inside a housing of a small device; and a ground expansion member which is mounted inside the housing, comprises one of the metal plate, the metal wire, or the connector FPCB, and has a first end connected to a ground line of the antenna.

Disclosed herein is an antenna device that includes a first coil pattern having at least first, second, and third turns. As viewed in a coil axis direction, each of the first, second, and third turns has an opening with a width larger in a first direction than in a second direction orthogonal to the first direction. The width of the opening of the second turn in the second direction is larger than a width of the opening of the first turn in the second direction. The width of the opening of the third turn in the second direction is larger than the width of the opening of the second turn in the second direction and smaller than a width of the opening of the first turn in the first direction.

Disclosed herein is an antenna module that includes a substrate on which a first coil is provided, a base material on which a second coil and a magnetic sheet overlapping the second coil are provided, and an adhesive layer bonding the substrate and the base material such that the first coil and the magnetic sheet overlap each other.

A loop type ground radiating antenna having dual resonance is disclosed. The antenna including a feeding path that traverses the ground clearance, creating a first portion and a second portion. One or more first capacitors are disposed along a first conductive path between the ground clearance and the edge of the ground layer, proximate the first portion, while one or more second capacitors are disposed along a second conductive path between the ground clearance and the edge of the ground layer, proximate the second portion. An input capacitor is used to feed the feeding path. The values of the input capacitor and the first capacitors determine a resonant frequency of the first feeding loop, while the values of the input capacitor and the second capacitors determine a resonant frequency of the second feeding loop. By proper selection of the capacitor values, a wide bandwidth may be created.
