Provided is a tag integrated circuit (IC) module apparatus and a method of fabricating tag IC module apparatus. The tag IC module apparatus may include an n-turn loop coil, n denoting a natural number, connected in series with a tag IC, and a printed circuit board (PCB) disposed below the tag IC and patterned with the n-turn loop coil.

Tag integrated circuit module apparatus and method of fabricating tag integrated circuit module apparatus

Provided are a method and apparatus for stopping power supply to a radio frequency identification (RFID) system. The apparatus includes: a power supplier supplying power to a high RFID tag; an input unit rectifying and boosting an input predetermined frequency band signal and outputting a direct-current (DC) voltage signal; a wake-up determiner comparing a voltage of the DC voltage signal output from the input unit with a predetermined reference voltage and outputting a HIGH signal or a LOW signal; and a switch stopping power supply to the high RFID tag if the wake-up determiner outputs the LOW signal.

Method and apparatus for stopping power supply in RFID system

An RFID tag includes an antenna and a chip, and the antenna includes a first polygonal dielectric material, first and second microstrip lines partially formed in the first dielectric material, a second polygonal dielectric material stacked on the first dielectric material, and a third microstrip line partially formed in the second dielectric material. According to the present invention, the RFID tag can efficiently receive electromagnetic waves to thereby maximize a readable range.

Radio frequency identification tag and radio frequency identification tag antenna

Provided are a radio frequency identification (RFID) tag and a wake-up method thereof. The RFID tag includes: a power source that supplies a driving voltage; a continuous wave detector that receives the driving voltage from the power supply so as to detect a continuous wave in a signal received from an RFID tag reader; a command detector that selectively receives the driving voltage and detects a command in the signal; and a controller that executes the command detected by the command detector by supplying the driving voltage to the command detector if the continuous wave is detected, and stops the driving voltage from being supplied to the command detector if no command is received from the command detector for a predetermined time period.

Lower power battery-assisted RFID tag having improved recognition distance, and wake-up method thereof
