这项工作提出了一个混合线性指数锥形槽的对极和共面Vivaldi天线在低频使用参数分析和非线性序列规划优化的关键属性的影响进行分析。结果表明,混合锥形槽可以扩展对映Vivaldi天线的频率下限,但增益和E面辐射方向图略有恶化。另一方面,优化的混合和传统的锥形槽共面维瓦尔第天线收敛到天线具有相同的性能结果。
This work presents an analysis of the effects of a hybrid linear-exponential tapered slot on the key properties of both the antipodal and co-planar Vivaldi antennas at low frequencies using parametric analysis and Nonlinear Sequential Programming optimisation. It was observed that the hybrid tapered slot can extend the lower frequency limit of the antipodal Vivaldi antenna however with slight deterioration of the gain and E-plane radiation pattern. On the other hand, the optimisation of the hybrid and conventional tapered slot co-planar Vivaldi antennas converged to antennas with the same performance results.
