异型单脊馈源喇叭的设计

Design of Peculiar Single Ridge Feed Horn

在已定型的天线上寄生实现某一特定功能的馈源,结构上受到很大限制,常规的形式无法满足结构要求。本设计采用了一种单脊弯曲渐展,口径阻抗匹配的思路,历经理论计算、仿真设计、实验修正,最终满足了电性能和结构性能的要求,完成了工程定型设计。

While autoecious feeder with some special functions is installed on the ease-hardened antenna, its structure may be limited strictly and the conventional form could not be satisfied. In this paper, a kind of feeder with single ridge is presented. The ridge is bended and spread step by step, so the impedance matches well. In order to obtain the optimized electrical performance and corresponding structure, the theoretical computations, simulations and experimental modifications are adopted. Thus, the engineering design and application are favorable.
