Technical field

The present invention relates to the field of schoolbags, and more particularly to smart packets involving intelligent identification systems and fused antennas.

Background technique

In the current prior art solution, the RFID (Radio Frequency Identification) technology is mainly used to identify the items in the package. Since the general RFID printed label antenna has a small area, the gain is low. Gain refers to the ratio of the maximum radiation intensity in the specified direction to the maximum radiation intensity of the antenna, that is, the antenna power amplification factor. In general, the strength of the gain will interfere with the antenna radiation or the ability to receive wireless signals. That is to say, the higher the gain, the more stable the propagation of the wireless signal, and the lower the gain, the more the signal propagation is compromised. Moreover, due to the uncertain spatial location and orientation of the tags in the package, some tags may have overlapping effects, or the location may be approximately perpendicular to the antenna of the identifier, resulting in missed reading of the tags. Not only that, if a single ceramic antenna is used, it is bulky and heavy, and the design of the single antenna has strong directivity.
