摘要
本文设计了一个工作在3-35GHz的常规平衡对踵Vivaldi天线,在此带宽范围内,S11均小于-10dB。后在此天线的基础上,通过加载半椭圆引向介质板和开半椭圆槽的方式,改善原天线在高频处E面方向图不对称的问题。两种天线都加工出实物,并进行了测量。实测结果表明,两种天线都符合3-35GHz的带宽设计要求,改进型天线E面方向图的峰值偏移现象得到显著抑制,还提高了增益。
In this paper,a conventional Balanced Antipodal Vivaldi Antenna operating at 3-35 GHz is designed.In this bandwidth range,S11 is less than-10 dB.On the basis of this antenna,the problem of E-plane direction pattern asymmetry of the original antenna at high frequency is improved by loading a semi elliptical guiding dielectric plate and opening a semi elliptical slot.Two kinds of antennas are manufactured and measured.The experimental results show that both antennas meet the bandwidth design requirements of 3-35 GHz.The peak shift of E-plane direction pattern of the improved antenna is significantly suppressed and the gain is improved.
