Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] see figure 1 , figure 1 It is a perspective view of the antenna device with bent microstrip lines of the present invention. The antenna device 10 includes: a dielectric substrate 110 , a bent microstrip line 120 , an input terminal 130 , a load resistor 140 and a through hole 150 . Wherein, a ground plane 111 is formed on the first surface of the dielectric substrate 110 . In practical implementation, the dielectric substrate 110 can be constituted by a thin single substrate, which can also be referred to as a base material, and is used to provide and establish conductor lines. Since the dielectric substrate 110 is a prior art, it will not be repeated here.

[0022] The bent microstrip line 120 is used to be disposed on the second surface of the dielectric substrate 110 and to read an electronic tag (not shown in the figure) by electr...

Abstract

The invention discloses a near field read-write antenna and a real-time asset management system. The near field read-write antenna is characterized in that a ground plane is formed on a first surface of a dielectric substrate, a bending micro-strip line is arranged on a second surface of the dielectric substrate and reads an electronic tag in electromagnetic coupling mode, and read asset information is transmitted to a database at the control end to be stored and managed. Therefore, the technical effects of improving reading uniformity, group reading performance and asset management efficiency, controlling communication distance and reducing environment influences can be achieved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a near-field read-write antenna and a real-time asset management system. Background technique [0002] In recent years, there have been more and more examples of radio frequency identification (RFID) applications in various industrial fields, and applications in new business models such as logistics, medical care, national defense, transportation, and real-time monitoring have continued to increase. RFID automatic identification technology has spread to various industrial sites, manufacturing facilities and real life in an evolutionary way. In the library stack or the display stand of the food store, use the smart shelf installed with the near-field antenna to manage the books in real time, provide the circulation history and various product information of the displayed goods, and form a new communication with the users model. [0003] At present, for the production and system maintenan...
