Abstract

The invention relates to a warehouse logistics forklift conformal RFID leaky cable multi-polarization MIMO antenna system, comprising a first RF channel, a second RF channel and a third RF channel which are arranged on a forklift, wherein the first RF channel is arranged on a forklift metal front panel, and form an open loop after vertically led out by a reader; the second RF channel and the thirdRF channel are located on the two sides of the first RF channel respectively; the second RF channel extends to a forklift arm; the third RF channel extends to the other forklift arm; the second RF channel and the third RF channel are both provided with a bent portion for avoiding the open loop; and the first RF channel, the second RF channel and the third RF channel are all equipped with openings. The warehouse logistics forklift conformal RFID leaky cable multi-polarization MIMO antenna system gives scope to the advantage that a leaky cable antenna is liable to be conformal to the forklift,so that the antenna system has multiple polarizations, and a tag reading rate can be increased.

Description

technical field

[0001] The invention relates to the field of RFID in tobacco logistics, in particular to a conformal RFID leakage cable multi-polarization MIMO antenna system for warehouse logistics forklifts. Background technique

[0002] The microwave radio frequency identification (RFID) technology developed based on the principle of radar backscattering (Back Scattering) communication is an antenna, non-contact automatic identification technology. There is no need to establish mechanical or optical contact between the identification system and a specific target. Identify specific targets and read and write related data through radio signals. RFID equipment includes RFID chips and RFID readers.

[0003] RFID technology applications can be used in production line automation, warehouse management, electronic item surveillance systems, identification of freight containers, and asset management, especially in warehouse asset management. At present, on the basis of tradition...
