DUAL-BAND DIPOLE ANTENNA USING MEANDER LINES AND STEPPED LINES FOR 433MHZ amp; 900MHZ RFID READER, CAPABLE OF MAINTAINING FREQUENCY DIVERSITY WHILE IMPLEMENTING A DOUBLE BAND FREQUENCY PROPERTY

摘要

PURPOSE: A dual-band dipole antenna using meander lines and stepped lines for 433mhz & 900mhz RFID reader are provided to maintain excellent performance by using meander lines and stepped lines.;CONSTITUTION: In a dual-band dipole antenna using meander lines and stepped lines for 433mhz & 900mhz RFID reader, a feeding part(301) has a specific impedance value and receives constant RF signal. Dipole antennas(302, 303) are connected to each other while facing to the feeding part. The dipole antenna is formed into a meander line and a stepped line The dipole antenna forms multi-resonance by combining antennas having different lengths. . 433MHz is formed by the meander line while 900MHz is formed by the stepped line.;COPYRIGHT KIPO 2012
