一种三频段小型化平面单极子印刷天线
compact tri-band planar monopole printed antenna
设计了一款三频段线极化平面天线。天线采用单极子的基本结构，仅采用一个馈点馈电，通过在主辐射片上添加缝隙，实现多频段,使天线辐射片尺寸为10mm*40mm；采用印刷制造，制造简单，成本低。天线工作频段包括：876MHz-960MHz，1710MHz-2160MHz和2500MHz-2690MHz，覆盖了GSM900，DCS，PCSLTE等频段。特别通过添加地支和寄生贴片明显增加频段的带宽。测试表明，中间频段VSWR<3的带宽可以达到600MHz以上。
In this paper，a tri-band linearly polarized planar anttena is presented. The antenna adap monopole as the basic unit and only has one feed point. Two slots are etched one the monopole to achieve multiple resonances.The size of radiation patch is 10mm*40mm.The antenna is printed on the PCB ,easily fabricated anf low cost.The antenna works on frequency bands of 876MHz-960MHz，1710MHz-2160MHz and 2500MHz-2690MHz,covers GSM900/DCS/PCS/LTE and other wirless services. Altering ground and parastic strip are applied in the antenna to broaden the bandwidth. The bandwidth of the middle band is over 600MHz according to test result.
