【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10d B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。更多还原

【Abstract】 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 6.9 GHz, The return loss value at the resonance point is-39.13 dB, the bandwidth is 2.46%(6.82～6.99 GHz) at return loss 10 dB. The antenna size is only 14 mm×14 mm×1.6 mm,The structure of the antenna is simple,miniaturization can be achieved and easily debugged with low cost and widely used.更多还原
