Broadband design of a shaped beam reflectarray with China coverage pattern
The paper presents the design of a three-layer printed reflectarray providing China coverage pattern for space applications. An optimization method was utilized in the design of the reflectarray to achieve a broad bandwidth of 11.85GHz-13.15GHz. To overcome the frequency band limitation of the reflectarray, the patch dimensions of the elements are optimized to match the required phase distributions for not only the central but also the extreme frequencies. The results show the achievement of desired coverage in the defined frequency band for the optimized reflectarray.
