摘要
提出了一种串馈微带天线设计方法,给出了设计原理和设计步骤。采用贴片加权方式,根据副瓣电平设计每个微带贴片的阻抗值,再由阻抗值确定贴片尺寸。各个微带贴片通过主馈线级联形成阵列。贴片与馈线之间通过三角形过渡调节为实阻抗,在阵列出口调节驻波。给出了天线的仿真和测试结果。
A design method of the series-fed microstrip antenna array is presented,the design principle and steps are given.The microstrip patch impedance is designed by the sidelobe level with patch weighting,the patch dimensions are decided by the patch impedance. Microstrip patches are serried by the main feeding line to be an array.The joint between the patch and the feeding line is adjusted to the real impedance by the triangle transition,the VSWR is adjusted to the array.The simulation and test results are both given.
