- Broadband low radar cross section antennas based on H‐shaped metasurface Huanhuan Yang Tong Li Kun Gao Zexu Guo Qi Li Sijia Li Xiangyu Cao Microwave and Optical Technology Letters AbstractThis paper presents a novel metasurface antenna element and a novel metasurface antenna array, both of which have broadband low radar cross section (RCS) performance. The antenna element is constructed by two kinds of H‐shaped metasurface unit cells. One kind of H‐shaped metasurface unit cells is properly fed to radiate, and the other unit cells are used to cancel the scattering field from the former. Thus, an integration of metasurface and antenna is performed and broadband low RCS is obtained. Furthermore, a H‐shaped metasurface antenna array is also proposed by deliberately introducing metallic vias for isolation. Both the proposed antenna element and the array have almost the same radiation performance with conventional patch antennas. Numerical calculations and experimental measurements are conducted. The results verify the effectiveness of the proposed novel antennas. 10.1002/mop.33965 http://onlinelibrary.wiley.com/termsAndConditions#vor
