摘要

本文提出了一种工作波段覆盖整个Ku波段的复合结构螺旋天线。天线的设计是等角螺旋和阿基米德螺旋的组合:天线元件内部为等角螺旋，外部为阿基米德螺旋。从而有效地减小了天线平面的尺寸。此外，为了抑制天线的前向辐射，实现平衡馈电，我们设计了改进的反射腔结构和指数梯度Balun。仿真结果表明，该天线的远场增益大于5dB，在Ku频段的驻波比小于2.5dB。

Design of composite spiral antenna loaded with a new type reflector in Ku-band

In this paper, we proposed a composite structure spiral antenna whose working band covers the entire Ku band. The design of the antenna is the composite of equiangular spiral and Archimedes spiral: The internal of antenna element is with equiangular spiral, and the external of is with Archimedes spiral. So the size of antenna plane is reduced effectively. Furthermore, in order to suppress the back forward radiation of the antenna and to achieve the balanced feed, we designed the improved reflector cavity structure and exponential gradient Balun. Simulation results show that the far-field gain of the antenna is higher than 5dB, and the VSWR is less than 2.5dB in the Ku band.
