Example Embodiment

[0028] The present invention will be further described below through specific embodiments.

[0029] Reference figure 1 , A high-gain reader / writer antenna for the RFID system of the fitting room, comprising a base substrate 10 and four side substrates 30. The base substrate 10 is provided with a power division feed network 20, and each side substrate 30 is provided with a quasi-yagi Antenna 40. The base substrate 10 and the side substrate 30 are both Fr4 glass fiber epoxy copper clad laminates, with a dielectric constant of 4.4 and a loss tangent of 0.02. A bottom ground plate 11 is further provided on the back of the bottom substrate 10, and the bottom ground plate 11 is a copper clad laminate.

[0030] The function of the power division feed network 20 is to distribute the power of the input end of the antenna to the quasi-Yagi antenna 40. In order to ensure the circular polarization characteristics of the antenna radiation, the power of the four output ends of the power divisi...

Abstract

The invention relates to a high gain reader writer antenna of a dressing room RFID system. The high gain reader writer antenna comprises a bottom substrate and multiple side substrates, wherein the bottom substrate is provided with a power division feed network, the power division feed network is provided with multiple power dividers so as to distribute signal input power to output signals which have identical amplitudes and sequentially-90-DEG-lagged phases, each side substrate is provided with a quasi-Yagi antenna, and the multiple quasi-Yagi antennas are connected with the power division feed network. The high gain reader writer antenna has advantages of high gain, excellent radiation performance, excellent circular polarization characteristic, simple antenna structure, light weight, convenient mounting and low cost.

Description

technical field [0001] The invention relates to the field of reader-writer antennas, in particular to a high-gain reader-writer antenna for an RFID system in a fitting room. Background technique [0002] In the clothing industry, the store is not only the location of the interaction link with customers, but also the final 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. In clothing stores, the fitting room is a key interaction place. If a certain type of clothing has been 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 it has entered the fitting room many times but has not been sold in the end, it means that the shape design of the clothing is relatively successful. However, there are still major problems in the specific details; if the number of t...
