摘要
为了使同轴线馈电矩形贴片天线有较高的辐射增益,获得更远的传输距离,在天线尺寸增大不多的前提下,采用相对介电常数较低的材料和尽可能大的介质板厚度,设计出了中心频率fr=3GHz,相对带宽3.47%,S11最小值-40.7542d B,最大增益为6.9785d Bi的贴片天线,性能明显优于相对介电常数较高的材料和介质板厚度较小的贴片天线。
In order to make the coaxial feed rectangular patch antenna with higher radiation gain and longer transmission distance, on condition that the antenna size is not more than the premise, a patch antenna with the center frequency f, = 3GHz, relative bandwidth 3.47%, Sn minimum value - 40.7542dB, maximum gain 6.9785dBi is designed using the material of low relative permitfivity and dielectric plate thickness as large as possible. The performance is better than that of the patch antenna using the material of high relative permittivity and large dielectric plate thickness.
