摘要: 文章创新性地提出使用二次贝塞尔曲线作为脊曲线模型，并结合一种创新的馈电结构，使电压驻波比(VSWR)在1~10 GHz频段内稳定于2以下，在1~10 GHz频段内匹配完美。通过参数化仿真优化发现，该馈电结构能够有效降低驻波比并提升增益。此外，脊倒角和空腔组合设计进一步减少了反射。基于参数化建模，采用遗传算法进行迭代参数优化，最终实现了在双指数函数脉冲源下的最佳匹配效果。该设计不仅性能优异，而且部件设计简单，便于后续加工，适用于多种辐射场景。
Abstract: This paper innovatively proposes the use of a quadratic Bézier curve as the ridge curve model, combined with an innovative feeding structure. As a result, the voltage standing wave ratio (VSWR) remains stable below 2 in the 1~10 GHz frequency band and achieves excellent matching in the 1~10 GHz frequency band. Parametric simulation optimization reveals that this feeding structure can effectively reduce the VSWR and improve the gain. Additionally, the combined design of the ridge chamfer and the cavity further reduces reflections. Based on parametric modeling, a genetic algorithm is employed for iterative parameter optimization, ultimately achieving the best matching effect under a double-exponential function pulse source. This design not only boasts excellent performance but also features a simple component design, facilitating subsequent processing. It is suitable for a variety of radiation scenarios.
