Abstract

The invention belongs to the field of wireless communication, in particular to a miniaturized and circularly polarized antenna for the RFID (Radio Frequency Identification) management field. When RFID is applied to managing materials in a movable container, requiring that RFID hardware devices in the container are miniaturized on the one hand, and an RFID reader has the characteristics of high efficiency and non-blind area for the read-write performance of the attached label of a managed material on the other hand. An antenna is used as receiving and transmitting terminal equipment of the RFID reader, thereby the performance indexes of the antenna are dominant factors for influencing the RFID reading-writing performance. Therefore, the miniaturized and circularly polarized antenna for the RFID material management in the movable container is designed in the invention, and the purpose of effectively managing movable material labels by an RFID system is realized.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a miniaturized and circularly polarized antenna used in the field of RFID technology management. Background technique [0002] The Chinese name of Radio Frequency Identification (RFID) is radio frequency identification technology. The radio frequency identification reader processes a large amount of relevant information carried by the tags on the identified objects through the communication base station, and establishes a database in the control background in the form of network transmission to realize the "information resource socialization" management function of the items. Since the radio frequency identification (RFID) technology laid its theoretical foundation in 1948, its original basic theory and basic technology have been very mature. However, with the popularization of Internet technology in recent years, logistics, commerce, transportation, military logistics, etc....
