With the development of the Internet of things, RFID technology has been widely used in logistics warehousing, retail, asset management, personnel management, intelligent manufacturing and other fields. With the continuous influx of more and more RFID enterprises and solution providers, exploring the application of UHF RFID technology in their respective industries, how to plan the system software and hardware and how to select the hardware has become an important problem for them. Here, jinruida electronics answers the characteristics of RFID far-field and near-field antennas, and analyzes the application of jewelry management to help you understand the UHF UHF RFID product selection.

First of all, let's learn about the selection of UHF RFID near-field and far-field antennas?

Here, jinruida electronics answers the characteristics of RFID far-field and near-field antennas, and analyzes the application of jewelry management to help you understand the UHF UHF RFID product selection.

First of all, let's learn about the selection of UHF RFID near-field and far-field antennas?

In many practical projects, customers don't know how to choose the antenna, especially they don't know what kind of antenna to use.

Far field antenna: recognition distance is long, radiation angle is large, easy to misread the tag beside;

Near field antenna: the recognition distance is close, and the radiation is only on the positive surface of the antenna, so the tag cannot be recognized in a long distance, but the tag next to it will not be read in series.

At present, the rise of various industries and fields at home and abroad, more and more people hope UHF RFID technology to help the development of their own enterprises. However, the application requirements of UHF RFID products are different in every industry, every field, every enterprise, even in different occasions of the same enterprise.

The following is about "how to ensure that only the tags in the specified area are recognized, and the tags next to them are not read?" Take the application of jewelry management as an example to tell you the key points of UHF RFID antenna selection

In the application of jewelry management, there are the following characteristics:

Different types of jewelry are placed in each shelf area;

Jewelry display is very close;

The jewelry should be 100% identified in the area;

Jewelry can no longer be read out of the area, let alone read the label in the display cabinet next door;

In this scenario, it is recommended to use UHF RFID near-field antenna.

The advantages of near-field antenna are as follows:

The electromagnetic field is only distributed on the positive surface of the antenna, which is due to the special design of the near-field antenna.

The design of the near-field antenna ring makes the efficiency of the antenna radiated concentrate on the positive surface of the antenna, so that the effect of recognizing multiple tags is better, the radiation angle is better controlled, the tags can be recognized normally on the antenna surface, and they can not be recognized when they leave, let alone the tags on the left and right side of other items, so as to achieve the real significance of jewelry management.
