以小型偶极子天线为研究对象，采用无选择和选择性2种不同的喷墨印刷方式印制，对比了2种印刷方式下天线的识别距离和油墨耗用量。实验证明，在表面电流密度较高处进行选择性印刷，以增加墨层厚度的方法，有利于降低喷墨印制无源超高频RFID标签天线的成本，性价比明显提高。

Small dipole antennas printed by full printing and selective printing were studied. The read range and ink consumption under the two conditions were compared. The results showed that the method of selective printing on the area of higher surface current density to increase ink layer thickness is propitious to reduce the cost of passive UHF RFID tag antenna and to improve its cost-effectiveness.
