RFID TAG ANTENNA OF AN ULTRA HIGH FREQUENCY BAND HAVING AN ISOTROPIC RADIATION PROPERTY CAPABLE OF FACILITATING SMALL SIZE MANUFACTURE

摘要

PURPOSE: An RFID tag antenna of an ultra high frequency band having an isotropic radiation property is provided to satisfy an optimum isotropic property and an impedance matching property.;CONSTITUTION: An RFID tag antenna of an ultra high frequency band having an isotropic radiation property includes a feeding loop(103), an L-shaped conductor pattern(211), a first meander conductor pattern(213), and a second meander conductor pattern(215). The feeding loop forms a closed loop with a tag chip. The L-shaped conductor pattern is faced with the feeding loop. The first meander conductor pattern is connected to one end of the L-shaped conductor pattern. The first meander conductor pattern is bent over two times. The second meander conductor pattern is connected to the other end of the L-shaped conductor pattern. The second meander conductor pattern is bent over two times.;COPYRIGHT KIPO 2010
