In this paper, a flat multilayer dielectric reflector antenna has been designed and analyzed. The reflector is made of several sandwiched dielectric layers. The structure is hence an array made of these layers, where the sum of the reflection coefficient of each layer acts as the array factor. By optimizing the permittivity and thickness of each layer, any desired reflection coefficient to shape the reflected pattern can be obtained. It is also possible to synthesize a zero or a maximum in any arbitrary direction. The significance of the reflector is ability to radiate high power and at the same time having small dimensions.
