摘要

本文提出了一种双端口环形槽谐振器天线作为RFID标签和读取器。在整个sub- 6ghz频段内，通过保持两种方向即相同方向和正交方向来测量散射参数。给出了前向链路和后向链路的路径损耗计算公式。在前向链路中，3.5 ~ 3.75 GHz频率范围内的路径损耗为24.45 ~ 72.64 dB，而在后向链路中，在同一频段内的路径损耗为21.70 ~ 66.96 dB。方向灵敏度证实，在5G频段的RFID系统中，所报道的天线可以在30厘米的距离内使用。

Path Loss of Two-Port Circular-Ring Slot Antenna For RFID Applications

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.
