Abstract
This paper presents a dielectric film with metal strips fed by the image line made of a high dielectric constant material. By using a 10.8 relative dielectric constant image line, wide and symmetrical beam-steering angle is achieved with a simple structure. Antenna size is also reduced compared to the image line antenna made of a low dielectric constant material.
