Heuristic experimental method for manufacturing RFID tag antenna pattern

Abstract

The invention discloses a heuristic experimental method for manufacturing a RFID tag antenna pattern. The method is characterized by comprising the following steps of: packaging the self-manufactured antenna pattern into a tag and comparing the performance of the tag with that of a tag in a standard pattern; finding an impact factor of the pattern; and optimizing the design of the antenna pattern. Compared with the prior art, the experimental method has the advantages of simple experiment and high heuristic property. Therefore, an experimenter understands the influence of the antenna pattern on the tag performance by repeatedly manufacturing and finely adjusting the tag antenna pattern, gets cognitive knowledge of the performance of an electronic tag, and better develops and designs a tag antenna pattern with good performance. Therefore, better effect is expected to be achieved, and the experimenter is enlightened to perform creative design.

Description

Technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to an experimental method for making a heuristic RFID tag antenna layout. Background technique [0002] RFID (Radio Frequency Identification, abbreviated as RFID) is a non-contact automatic identification technology that uses radio frequency signals and spatial coupling to automatically identify target objects and obtain relevant data, without manual intervention. A typical RFID system consists of tags, readers, middleware and upper-level application software. Among them, RFID tags, commonly known as electronic tags, are the primary factor in system deployment and consist of chips and tag antennas. RFID tag antennas mainly have three basic forms: coil type, microstrip patch type, and dipole type. [0003] RFID technology has many advantages such as high accuracy, strong ability to adapt to the environment, long reading distance, strong anti-interference ability, an...

Problems solved by technology

Because the shapes of these existing layouts are very different, it is difficult for the experimenter to vividly understand the influence of the layout on the performance of the label by comparing them, so the existing experiments are not very enlightening.

It is limited to experiments and tests on the performance of various existing tags, so it can only compare the tag performance of several existing antenna layouts, but it is impossible to study the impact of different antenna layouts on tag performance in a targeted manner. heuristic value

Although there are some simulation design software for tag antennas, which can make antenna simulations and test their performance in a simulation environment, there is a large difference between the test results and the results in the actual environment, and there is no substantive guidance Significance and reference value
