摘　　要：现代通讯产品向小型化的趋势发展,对作为射频端的收发天线的尺寸也有了一定的要求,本文在一种基于同轴馈电的矩形微带天线的基础上,采用对天线贴片进行切口处理的方法,并通过天线仿真优化软件HFSS设计了一款微带天线,该天线在频率6.90GHz产生谐振,在谐振点上回波损耗值为-39.13dB,通过仿真分析,对应的10dB回波损耗带宽为2.46%(6.82~6.99GHz),该天线尺寸为14mm×14mm×1.6mm,该天线结构简单,加工调试方便,且达到了小型化的要求,具有很好的应用前景。Modern communication products are developing towards miniaturization,and there are certain requirements for the size of the transmitting and receiving antennas as the RF end.In this work,a rectangular microstrip antenna based on coaxial feed is proposed with the method of cutting antenna patch,is simulated and designed by HFSS which is a software for emulating antennas.The antenna generates resonance at a frequency of 6.9GHz,The return loss value at the resonance point is-39.13dB,the bandwidth is 2.46%(6.82~6.99GHz)at return loss 10dB.The antenna size is only 14mm×14mm×1.6mm,The structure of the antenna is simple,miniaturization can be achieved and easily debugged with low cost and widely used.
