Abstract
The present invention relates to a broadband RFID (Radio Frequency Identification) label (tag) antenna that includes a base, a label chip, and an antenna module. The present invention is applicable in a surface of a metal object. Thereby, a microstrip antenna with a miniaturized label antenna is accomplished. Moreover, a dual mode is applied for conquering problems brought about by the narrowband of the microstrip antenna, and the antenna is bended and miniaturized. Accordingly, preferable impedance match is achieved between the antenna and the chip.
