RECTANGULAR LOOP ANTENNA HAVING MEANDER STRUCTURE FOR RFID TAG

摘要

A rectangular loop antenna having a meander structure for an RFID(Radio Frequency Identification) tag is provided to reduce a size thereof by having the meander structure in which pulse type lines of triangular meander line units are congregated in a truncated triangular shape. A rectangular loop antenna(A) having a meander structure for an RFID tag includes a substrate(100) and a rectangular loop element(200). The substrate has a predetermined dielectric constant. The rectangular loop element is composed of four triangular meander line units(210-240), wherein a hypotenuse of the triangular meander line unit is separated from the hypotenuse of the adjacent triangular meander line unit by a predetermined distance. Each of the triangular meander line units is composed of a plurality of pulse type lines congregated in a truncated triangular shape.
