An RFID system reader antenna for fitting rooms based on miniaturization technology

Abstract

The invention relates to a miniature technology-based reader-writer antenna of a radio frequency identification (RFID) system of a dressing room. The antenna comprises a power division feed network and four quasi-Yagi antennas, wherein the power division feed network is horizontally arranged, the four quasi-Yagi antennas are arranged around the power division feed network and are perpendicular to the power division feed network, the power division feed network comprises a grounding copper sheet, a substrate and a feeder part which are arranged in a lamination way, the feeder part comprises a first-stage power division part and a second-stage power division part which are connected, four power equal division output ports are formed for the four quasi-Yagi antennas, and each quasi-Yagi antenna comprises a port feeder, a balance Balun, a differential feed network, an oscillator feeder and a feed source oscillator which are sequentially connected. By the antenna, signal radiation within a range of the dressing room can be achieved, the antenna has relatively high directional capability, and the miniature design is satisfied as well as the signal grain is achieved.

Description

technical field [0001] The invention relates to the technical field of RFID antennas, in particular to a reader antenna for an RFID system in a fitting room based on miniaturization technology. Background technique [0002] At present, the RFID industry has begun to be widely used in many fields such as logistics, transportation, and clothing. In the clothing industry, the store is not only the location of the interaction link with customers, but also the last link of clothing sales. If the data generated in the store can be analyzed and fed back in time, it will undoubtedly have important guiding significance for clothing manufacturers and store sales staff. The fitting room in the clothing store is also a key interactive place. If a certain type of clothing is taken into the fitting room many times and finally sold successfully, it means that the design and sales of the clothing are very successful; if entering the fitting room many times But it was not sold in the end, w...
