TAG ANTENNA FOR A RFID

摘要

PURPOSE: A tag antenna for RFID is provided to symmetrically connect short stubs in a loop radiator, thereby reducing nulls of a radiating pattern. CONSTITUTION: A tag antenna for RFID(Radio Frequency Identification) includes a tag antenna and a tag chip(104). The tag antenna is made of a dielectric substrate(100) and a specific pattern(102). The dielectric substrate is made of a dielectric material having a predetermined dielectric constant. The dielectric substrate is made of paper or polyimide film.
