摘要
设计了一种新型全向高增益印刷天线。该天线采用平衡微带线作馈线．以印刷振子作为辐射单元，末端采用匹配电路对其输入阻抗进行匹配。用商用软件AnsoftHFSS对天线的特性进行了仿真计算。比较表明，测试结果优于仿真结果。该天线工作在SCDMA频段（1785～1805MHz），其H面不圆度小于1dB，中心频率下增益大于12dB，满足了设计要求。
A novel high-gain omni-directional printed antenna is presented. Balanced micro-strip line is utilized as feed line, printed dipole is adopted as radiation element, and a matching network is employed for tuning the input impedance of the antenna. The characteristics of this antenna are calculated by Ansoft HFSS simulation software, and the measured data prove to be better than the simulation results. The novel printed antenna works in the SCDMA band（1785-1805 MHz）, and its gain is greater than 12 dB with small variations（〈1 dB） in H plane. Experimental results demonstrated the good performance of this antenna.
