| 摘 要： | 介绍一种新型E型结构的微带天线。在U型微带天线中间加一段传输线构成新型E型微带天线,产生多点谐振,达到微带天线频带展宽的目的。通过改变馈电点位置和传输线的长度和宽度,实现微带天线的最佳匹配和频带的展宽。仿真结果表明,该天线在4.25～5.366GHz频带内反射系数均小于-10dB,方向最大增益达到9dB,相对带宽为23.2%。且对E型天线加工和测试,实测结果和仿真结果一致。

| Abstract: | A new E-shapped microstrip antenna is introduced.A transmission line was added into the middle of U-shapped microstrip antenna,which constituted a new E-shapped microstrip antenna,resulted in more resonance to broaden the frequency band.By adjusting the position of feeding point and the length and the width of the transmission line,the proposed antenna achieved the best impedance matching and the bandwidth broadening.The simulated results show that the reflection coefficient of the antenna in 4.25~ 5.366 GHz band is less than-10 dB,the direction of the gain is 9 dB,the relative bandwidth is 23%.E-shapped microstrip antenna is manufactured and tested,the result is agree with the simulated result. |
