| 摘 要： | 基于对宽带宽覆盖角天线的需求，设计了一种工作于9~11 GHz的小型化对跖Vivaldi天线。在天线开口末端加入矩形引向器，以获得良好宽带匹配效果。利用HFSS软件进行结构优化，得到天线的具体参数，由此加工和测试带引向器的对跖Vivaldi天线。通过仿真和实测得到，在9~12 GHz频带内回波损耗小于-15 dB，在-10 dB以下的带宽为6.9~14 GHz。同时，通带内3 dB波束宽度实现±30°的扫描范围。此时天线的尺寸仅为15 mm?16 mm?0.762 mm，是一种宽带宽覆盖角的小型化天线。

| Abstract: | Based on the demand for antenna with wide-bandwidth and wide coverage angle, a miniaturized antipodal Vivaldi antenna is designed for 9 GHz to 11 GHz. A rectangle director is added to the back end of the antenna for better broadband matching effect. The HFSS software is used for structural optimization to obtain the specific parameters of the antenna. The antipodal Vivaldi antenna with the director is processed and tested. Through simulation and actual measurement, the return loss is less than -15 dB in the 9-12 GHz band, and the bandwidth below -10 dB is 6.9-14 GHz. At the same time, 3 dB beam width enables ±30° coverage range. The size of the antenna is only 15 mm?16 mm?0.762 mm. The proposed antenna is a miniaturized one with a wide bandwidth and wide coverage angle. |
