报道了一种专为 RFID 应用而设计的新型三频 CPW 馈电天线。该天线限于 ɛr=4.4 的 PCB 板上的 30×30 mm2 面积，具有四个 U 形槽、两个 F 形槽和两个 L 形槽作为附加谐振器，以实现多频段操作。智能单粒子优化 (ISPO) 算法用于同时确定最佳槽位配置，以实现 0.92、2.45 和 5.8 GHz 下的最佳回波损耗。通过使用有限元方法进行模拟来表征所设计的天线的性能。
A novel tri-band CPW-fed antenna designed for RFID applications is reported. Limited to 30×30 mm2 area on a PCBoard with ɛr=4.4, the antenna has four U-shaped, two F-shaped and two L-shaped slots as additional resonators to achieve multi-band operation. The intelligent single particle optimisation (ISPO) algorithm is used to determine the optimised slot configuration for the best return loss at 0.92, 2.45, and 5.8 GHz simultaneously. The performance of the designed antenna was characterised through simulations using the finite element method.
