Abstract
In this paper, two-port circular-ring slot resonator antennas are proposed as RFID tag and reader. The scattering parameters are measured by keeping these antennas in two orientations i.e. same orientation and orthogonal in the complete sub-6 GHz band. Formulas are presented for the forward link and backward link to obtain the path loss. In the forward path, the path loss is found from 24.45 dB to 72.64 dB in frequency range 3.5 to 3.75 GHz while for the backward link, it is 21.70 dB to 66.96 dB range in the same frequency band. Orientation sensitivity confirms the reported antennas can be useful up to 30 cm distance in RFID systems for the 5G frequency band.
