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.
