【摘要】 本文提出了一种基于扼流槽加载的宽带双频共口径Vivaldi天线。通过在传统Vivaldi天线的辐射臂口径边缘和尾部增加扼流槽,在提升低频段天线增益的同时,口径边缘处加载的扼流槽还可作为高频天线产生辐射。基于此扼流槽加载的Vivaldi天线能够在低频的C波段实现VSWR<1.8,相对带宽可达66.7%。在高频的30～34 GHz频带范围内实现VSWR<1.7,最大增益可达13.3 dB。更多还原

【Abstract】 This paper proposes a broadband dual-frequency co-aperture Vivaldi antenna based on choke slot loading.By adding choke slots at both the aperture edge and the trailing end of the radiation arm of a conventional Vivaldi antenna,the gain of the low-frequency band is enhanced.Meanwhile,the choke slot loaded at the aperture edge also serves as a radiator for the high-frequency antenna.The designed Vivaldi antenna,based on this approach,achieves a VSWR<1.8 in the low-frequency C-band,with a relative bandwidth reaching 66.7%.In the high-frequency band ranging from 30 to 34 GHz,it also achieves a VSWR<1.7,with a maximum gain of up to 13.3 dB.更多还原
