a robust uhf near-field rfid reader antenna This research proposes a system board of integrated antenna scheme of near-field communication (NFC) and dual band ultra-high frequency (UHF, 920–925 MHz)/2.45 GHz . NFC cards with a hole are special NFC cards that can be hung on a lanyard or used for labeling devices and similar purposes. Ordinary NFC cards should not be punched because the antenna usually runs along the edges of the cards or .

A novel ultrahigh frequency (UHF) near-field radio-frequency identification (RFID) reader antenna based on the complementary split ring resonator (CSRR) elements is presented in this communication. The antenna consists of a power divider and two arms. A novel UHF RFID reader antenna based on CSRR elements, which provides a uniform and strong magnetic field in the near field, is proposed in this paper. Through the processing and testing of the antenna, the prototype provides a reading range of 10 mm for near-field tag, 70 mm for far-field tag and 60 mm for anti-metal tag.
