摘要：
A miniaturized ultra-wideband Vivaldi antenna with bandwidth from 600MHz to 6GHz was designed. A coplanar structure is adopted to reduce cross-polarization levels. Meanwhile, an optimized method of slotting and tailing anti-flow fences on both sides of the antenna in which the load resistance ensures the compactness of the structure is used in order to expand the working bandwidth of the antenna to the low frequency and realize the miniaturization design. The size of the entire antenna is 100mm x 220mm x 1.5mm. The full-wave simulation of the designed antenna is carried out by the software HFSS, and the performance parameters of the antenna, such as return loss, standing-wave ratio and direction diagram, are given. The results are basically consistent with the theoretical design and meet the requirements of the standard receiving antenna for the antenna near-field test system.
