Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the following description.

[0023] like figure 2 As shown, it is a schematic diagram of the three-dimensional structure of a metal-resistant UHF electronic tag antenna conformal to the wall of the oil pipe casing provided by the present invention; it includes a dielectric substrate, a patch structure on the upper surface of the dielectric substrate and a tag chip, and The surface of the metal base plate, metal vias. Wherein, the patch structure is an axisymmetric structure, including a semi-circular radiator 4, and a feed ring 5 with an opening located in the middle of the patch structure. There is a gap 9 between the feed ring and the radiator, and the radiator Five rectangular slots are respectively set on the left and right sides of the body; the label chip is set...

Abstract

The invention discloses an anti-metal ultrahigh-frequency electronic tag antenna conformal to a petroleum pipe sleeve wall, and relates to the technical field of ultrahigh-frequency radio frequency identification. The ultrahigh-frequency electronic tag antenna is a semi-annular structure, is tightly attached to the petroleum pipe sleeve wall, and comprises a dielectric substrate, a patch structure, a tag chip and a metal bottom plate, wherein the patch structure and the tag chip are located on an upper surface of the dielectric substrate, and the metal bottom plate is located on a lower surface of the dielectric substrate. The patch structure is an axisymmetric structure and comprises a semi-annular radiator and a feed ring with an opening, A left side and a right side of the radiator areprovided with a plurality of rectangular grooves with the same number, the feed ring with the opening is located in the middle of the patch structure, a tag chip is located at the opening of the feedring, and the metal bottom plate completely covers the lower surface of the dielectric substrate. The ultrahigh frequency electronic tag antenna has advantages of a good anti-metal characteristic, simple processing, low cost, a high gain, a long readable distance and a large bandwidth, and can be well applied to a designed frequency band.

Description

technical field [0001] The invention relates to the technical field of ultra-high frequency radio frequency identification (UHF RFID), in particular to an anti-metal tag antenna adopting a planar inverted F antenna (PIFA) structure conformal to the casing wall of an oil pipe. Background technique [0002] At present, most of the management methods for petroleum-specific pipes are handwritten. This kind of work method not only has a large workload and low efficiency, but also makes mistakes and forgets unavoidably in the face of a large amount of data. The pipeline management system based on RFID technology can realize the wireless collection, wireless transmission and centralized management of the basic data of special oil pipes, realize the effective tracking and efficient management of special oil pipes, and can well solve the problems existing in manual management. [0003] The common electronic tags that can be used on the casing wall of oil pipes at this stage have the ...
