Abstract: The realization of broadband absorption has been one of the major research problems on metamaterials absorber.The fishbone-shaped broadband metamaterials absorber has been designed in this paper.Using commercial electromagnetic simulation software Microwave Studio CST,the absorption property has been calculated and analyzed.The results show that the fishbone-shaped metamaterials absorber can bring about high absorption over a wide frequency range and the absorption rate can remain at 90% between 89.6894.36GHz.It has the advantages of simplicity,being easy to prepare and so on.
