A vehicle window includes a first glass pane, a transponder having an antenna and a control unit for communicating with a reader, wherein the control unit includes a memory for storing identification data. A reflector is associated with and spaced apart from the transponder for increasing an antenna gain of the antenna, wherein the reflector is implemented as a transparent, electrically conductive coating and/or as a metallic ring.

A dual band transponder comprises a carrier substrate having at least one planar substrate layer. An ultra-high frequency loop antenna is mounted on a first surface of one of the planar substrate layers of the carrier substrate. A high frequency loop antenna is mounted on two opposite surfaces of one of the planar substrate layers of the carrier substrate. The ultra-high frequency loop antenna encloses the high frequency loop antenna in a plane parallel to the at least one planar substrate layer entirely. A textile label includes a textile label substrate and a corresponding dual band transponder mounted onto the textile label substrate.

A label includes a recycled sloop type radio frequency identification (RFID) tag from a previously used label. The RFID tag is removed from the previous label by cutting the RFID tag from the previous label using a laser, die, or cutting wheel. The conductor antenna of the RFID tag can be cut to remove damaged portions or change operation of the RFID tag. A slot in the conductor antenna can be resized to tune the RFID tag to allow the RFID tag to be used for the same application use or a different application use. The label can include indicia such as machine readable indicia and human readable indicia. The extracted RFID tag can include portions of the previous label, which can be free of indicia.

A mounting base for use with a wirelessly locatable tag may include a base portion defining a latching member configured to engage a wirelessly locatable tag to releasably retain the wirelessly locatable tag to the mounting base, a contact block attached to the base portion and configured to be positioned at least partially within a battery cavity of the wirelessly locatable tag, the contact block defining a top side and a peripheral side. The mounting base may further include a first conductive member positioned along the peripheral side of the contact block and configured to contact a first battery contact in the battery cavity of the wirelessly locatable tag, a second conductive member outwardly biased from the top side of the contact block, the second conductive member configured to contact a second battery contact in the battery cavity of the tag, and a power cable coupled to the base portion.

A chip packaging structure includes a miniature antenna, an identification chip, and a packaging main body. The identification chip is electrically connected to the miniature antenna.

The at least one stress reducing structure is provided at at least one of the corner portions. In addition, a method of making the chip packaging structure and a wireless identification tag having the chip packaging structure are also provided.

A BLUETOOTH electronic tag is provided, including an upper cover and a substrate, a circuit board is disposed on the substrate, and an electronic tag control circuit is disposed on the circuit board; the electronic tag control circuit includes a power circuit, a power protection circuit, a main control circuit, a BLUETOOTH transmission circuit, an identification circuit, and an electronic tag circuit; the power circuit is configured to provide power to the main control circuit through the power protection circuit; the main control circuit is configured to control the identification circuit through the BLUETOOTH transmission circuit, and the identification circuit is configured to transmit identification information to the electronic tag circuit. The BLUETOOTH electronic tag has complete functions, a stable and unimpeded information transmission, a convenient usage, and a good practicability, which improves a work efficiency.

A diaper wetness detection system includes a diaper, a wetness sensor, an RFID unit, and a transceiver unit. The RFID unit is a battery-less device that receives an interrogation signal transmitted by the transceiver unit. The RFID unit or the transceiver unit are configured to determine if a measurable characteristic, as sensed by the wetness sensor, indicates if the diaper is wet. The measurable characteristic can be a voltage or current indicative of a resistance, capacitance, or impedance at an area sensed by the wetness sensor. The value of the measurable characteristic is different when the diaper is wet versus dry. Comparing the measurable characteristic value to a threshold value or to one or more previously sensed measurable characteristic values enables a determination to be made as to whether or not the diaper is wet. The RFID unit can be detachably coupled to the diaper for simple attachment and removal.

An RFID includes a first conductive layer; a second conductive layer in which an antenna is formed; an insulating layer; and an IC chip. The antenna includes a first slot; a second slot facing the first slot; a coupling slot to couple the first slot with the second slot; a first adjustment slot coupled with one end of the first slot, and being wider than the first slot; a second adjustment slot coupled with another end of the first slot, and being wider than the first slot; a third adjustment slot coupled with one end of the second slot, and being wider than the second slot; a fourth adjustment slot coupled with another end of the second slot, and being wider than the second slot.

According to various embodiments disclosed herein, an electronic device comprises: a front plate including a front surface facing a first direction and a first portion of a side surface extending from the front surface; a frame forming a second portion of the side surface and on which electronic components of the electronic device sit; a rear cover including a rear surface facing a second direction opposite the first direction and a third portion of the side surface extending from the rear surface to the second portion of the side surface; a mmWave antenna module including a mmWave antenna disposed in one region of the frame and configured to form a beam in a third direction forming an obtuse angle with the first direction and an acute angle with the second direction; and a wireless communication circuit electrically connected to the mmWave antenna module.
