Ultrahigh frequency radio-frequency identification (UHF RFID) tags have shown enormous potential in wearable applications for sensing human vital signs. However, the integration of UHF RFID tags in ...

Industrial IoT security demands an integrated approach from the edge devices themselves—including RFID readers, controllers, and sensors—through internal communication layers and up to the cloud.

This research introduces a novel circularly polarized compact antenna designed for universal ultrahigh-frequency (UHF) radio-frequency identification (RFID) handheld readers for Bi-directional RFID ...
