摘　　要：文中设计了一种工作在频段1~1.2 GHz采用共面波导(CPW)馈电的贴片单极子天线。该贴片天线印刷在相对介电常数4.5,厚度为1.6 mm的FR4的介质板上,背面添加的金属反射板确保天线的定向性指标达到设计的要求。仿真使用基于有限差分的三维电磁仿真软件,设计的贴片天线回波损耗、方向图等参数达到要求的指标。对该天线回波损耗的实际测量结果和仿真结果对比表明,在整个目标频段内吻合较好,满足设计指标要求。A coplanar waveguide(CPW)-fed monopole antenna working at1~1.2GHz is designed which is printed on a FR4plate with a thickness of1.6mm and a dielectric constant of4.5.The directivity of the antenna matches well to the desired parameters with an added metal reflector behind the antenna.Three dimensional electromagnetic simulation software was used to optimize the parameters of the antenna.The return loss and the pattern of the designed antenna reaches the desire ones.The monopole antenna is manufactured and tested.The comparison with tested results and the simulation ones shows the good agreements with the design requirements in whole target frequency range.
