Embodiment Construction

[0025] Such as Figure 1~6 As shown, the present invention discloses a monopole tag antenna, including a buckle-back metal reflector 1, a dielectric substrate 2, a monopole 3, a metal ring 4 and a feeder 5, and a buckle-back metal reflector 1 Located at the bottom of the monopole tag antenna, the buckle-back metal reflector 1 is connected to the monopole 3 through the feeder 5, the dielectric substrate 2 is set on the monopole 3, and the metal ring 4 is set on the dielectric substrate 2 surface. Among them, the adoption of the buckle-back metal reflector 1 and the loaded metal ring 4 can reduce the overall height of the monopole tag antenna, and at the same time can increase the impedance bandwidth of the monopole tag antenna. The feeding inner conductor of the power feeding part 5 is welded on the monopole 3 , and the feeding outer conductor of the power feeding part 5 is welded on the buckle-back metal reflector 1 .

Abstract

The invention relates to the technical field of antennas, in particular to a monopole label antenna. The monopole label antenna comprises a back buckle-type metal reflection plate, a dielectric substrate, a monopole, a metal round ring and a feeding part, wherein the back buckle-type metal reflection plate is arranged at the bottom of the monopole label antenna and is connected with the monopole via the feeding part, the dielectric substrate sleeves the monopole, and the metal round ring is arranged on an upper surface of the dielectric substrate. The monopole is used as a main body of the antenna, works within a broadband range of 2.4-2.5GHz and covers a 2.4G band of a WIFI band, and moreover, the omnibearing performance of the antenna can be achieved by the monopole. The monopole label antenna is simple and compact in structure and low in processing cost, and is easy to process and simple to assemble.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a monopole tag antenna. Background technique [0002] Radio frequency identification technology is a non-contact automatic identification technology. It uses radio frequency signals to transmit information through spatial coupling and achieves the purpose of automatic identification of objects through the transmitted information. The identification process does not require manual intervention and can work in various harsh environments. Smart home, supply chain management, logistics trade, public security and other fields have a wide range of applications. [0003] Tag antenna plays a very important role in radio frequency identification technology. As the application environment becomes more and more harsh, the overall size of the tag is required to be smaller. The size of the tag antenna is of course a problem that needs to be solved; in addition, the tag antenna The gain of t...
