This paper presents the design of a wideband polygonal directional beam antenna based on the ray inserting method. The wideband characteristic of the directional beam antenna is achieved thanks to the use of inhomogeneous dielectric material. Also, unlike most previous works, the present design can be implemented with the isotropic and above unity refractive index materials, consequently simplifying its fabrication process. The finite difference time domain scheme is used to evaluate the directional beam antenna.
本文介绍了一种基于射线插入法的宽带多边形定向波束天线的设计。由于使用了非均匀介电材料,实现了定向波束天线的宽带特性。此外,与大多数先前的工作不同,本设计可以用各向同性且折射率大于1的材料来实现,从而简化了其制造过程。采用时域有限差分法对定向波束天线进行评估。
