摘要
从矩形微带天线的输入阻抗出发,利用天线谐振导模对微带天线阻抗的影响,提出了展宽微带天线频带宽度的方法。在高介电常数情况下,激起TE01模和TM01模时,相对带宽可以从单模时的0.7%展宽到2.7%;并给出了仿真结果。
From the input impedance of the rectangular micro strip antenna,the dual-mode of the micro strip antenna is used.By using the mode,the relative bandwidth could reach to 2.7% from 0.7%,which calculated under the high relatively dielectric constant.The simulation result is given at the same time.
