摘　　要：提出了一种用于电力230 MHz无线专网的平板天线,天线工作频率228~237 MHz,相对带宽3.9%。该天线由单层1 mm厚度FR4印制板的倒F结构辐射体组成,天线整体尺寸300 mm×260 mm×1 mm。天线通过匹配传输结构将馈电点放置于辐射体背部,便于安装。经过仿真天线增益性能良好,水平全向增益1.5 dBi,电压驻波比优于2。设计的天线经过微波暗室实地测试,测试结果与仿真结果吻合。An inverted-F antenna for 230 MHz wireless private network is presented whose operation band is 228~237 MHz and relative bandwidth is 3.9%.This antenna is composed of a single layer FR-4 substrate and its size is 300 mm×260 mm×1 mm.The feed position of the antenna is located on the back of the radiation patch in order to facilitate installation.Full electromagnetic HFSS simulation result shows the good performances of the antenna.The omnidirectional gain reaches 1.5 dBi and the voltage standing wave ratio(VSWR)is below 2.The measured results are in good agreement with the simulation ones.
