摘　　要：本文设计了一种用于ISM频段的双频单极子天线.天线由铲形辐射单元和共面波导馈电结构组成.通过在辐射贴片和馈线上分别刻蚀U型和S型缝隙产生一个宽阻带,使天线实现双频带特性.天线结构紧凑,尺寸为26mm×34mm.仿真结果表明:该天线可以工作在2.10~2.77GHz和5.19~6.2GHz两个频段,在工作频带内具有良好的辐射特性.In this letter, a dual-band monopole antenna is proposed for ISM band. The antenna consists of a spade radiation element and a coplanar waveguide feed structure. By etching a U-shaped slot on the radiation patch and an S-shaped slot on the feed line, a wide notched-band is introduced and then the dual-band property is achieved. The proposed antenna has a compact size of 26 mm×34 mm. The simulation results show that the antenna can work in 2.10~2.77 GHz and 5.19~6.2 GHz. Also, the antenna has good radiation characteristics within the operating band.
