摘要
提出一种加载引向器的小型化对跖Vivaldi天线(AVA)。相比大多数对跖Vivaldi天线,该天线具有非常小的尺寸,其大小只有14?mm×34?mm×0.8?mm。引向器结构设置为三角形,置于天线的开口中间。相比传统的对跖Vivaldi天线,引向器能引导电磁波从天线的口径传输到介质板的边缘,这样造成的反射比较小且传输特性良好。此外,为了减小测量误差,将天线与超小型(SMA)头联合仿真,结果表明,该天线在5.2~11?GHz频段内S11<-10?dB,具有较宽的带宽;且在8.5~11 GHz范围内,天线的增益明显增加,验证了这种新设计的可行性。
Abstract
A miniaturized Antipodal Vivaldi Antennas(AVA) with loading director is proposed. Compared with most of the antipodal Vivaldi antennas, the proposed antenna has a very small size which is only 14 mm×34 mm×0.8 mm. The director is provided with a triangle and placed between the openings of the antenna. It guides electromagnetic waves emitting from the aperture of the antenna to the edge of the conductive director with a smaller reflection and better transmission characteristics compared to that of the traditional AVAs. In addition, in order to reduce the measurement error, the antenna is combined with the Sub Miniature A(SMA) head. The results show that the antenna has a wide bandwidth from 5.2 to 11?GHz for S11<-10 dB, and the peak gain of the antenna is apparently increased in the range of 8.5-   11 GHz, which validates the feasibility of this novel design.
