Inverse-Designed Metal-type Antenna Superstrate for Shaped-Beam Radiation Pattern

An inverse-design method for metal-type antenna superstrate to get the desired shaped-beam radiation pattern is investigated by using the contrast source inversion method. The proposed inverse design method can avoid the shortcomings of the traditional forward-design methods in which antenna structure depends on a prior knowledge. Meanwhile, its feature of not relying on engineers' experience can greatly reduce the time cost in the design. Final results show that the proposed method has a good application prospect in antenna field.
