Abstract

The invention belongs to the field of wireless communication, in particular to circularly polarized MIMO antenna system design technology used in the RFID technical management field. When managing warehouse and logistics and materials, the radio frequency identification technology requires an RFID reader to have the characteristics of high efficiency, region control and no dead zone in region on reading and writing performance of an attached label of a controlled material. An antenna as a receiving and transmitting terminal device of the RFID reader, the performance indexes of the antenna are dominating factors influencing the reading and writing performance of RFID. Therefore, the invention designs a circularly polarized MIMO antenna system used in the RFID technical management field, which mainly comprises an RFID control chip, a radio frequency link switch, a radio frequency coaxial cable and a circularly polarized MIMO antenna unit which works in an HUF frequency band. The system can well achieve the aims of no dead zone management and region control management of the RFID reader on the label of the controlled material.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a circularly polarized MIMO antenna system 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. Onl...
