介绍了一种工作频率为5.8 GHz的RFID标签电小型片上天线。该天线尺寸为2.1 mm （λ/25） × 1.2 mm (λ/50)，采用0.18µm纯CMOS技术实现。天线由两个回路组成。通过改变内环的大小，我们可以在保持天线增益的同时控制天线阻抗。天线增益为- 22.21 dBi，带宽为4.9 GHz。
An electrically small on-chip antenna for RFID tags operating at 5.8 GHz is presented. The proposed antenna has dimensions of 2.1 mm (λ/25) by 1.2 mm (λ/50), implemented in a 0.18 µm pure CMOS technology. The antenna consists of two loops. By changing the size of the inner loop, we can manage the antenna impedance while maintaining its gain. The antenna has a gain and a bandwidth of −22.21 dBi and 4.9 GHz, respectively.
