BROADBAND U-SHAPED RFID TAG ANTENNA WITH NEAR-ISOTROPIC CHARACTERISTIC, INCLUDING A FEEDING PART INSIDE A DIPOLE ANTENNA OF U SHAPE

摘要

PURPOSE: A broadband u-shaped RFID tag antenna with near-isotropic characteristic is provided to perform impedance conjugate matching by offsetting the capacitive component of the tag chip.;CONSTITUTION: A dipole antenna having an U-shaped comprises a first conductor(122) and a second conductor(124). Each first conductors has a first width. Each of first conductors is parallelly located from each other by a first distance. A second conductor has the second width. The second conductor interlinks first conductors. A feeding unit(140) is connected to the second conductor. The feeding unit is located between first conductors.;COPYRIGHT KIPO 2010
