Abstract An equivalent circuit method of performance estimation for hexagonal loop composite absorbing metamaterial is proposed, and the corresponding equivalent circuit model is established. Based on the Fourier analysis of hexagonal lattice distribution, the equivalent distribution periodic parameter is proposed and the
estimation method of RLC parameters is given according to the size of units. The applicability and accuracy of the equivalent circuit model for several structure dimensions are verified and compared with HFSS. A sample is fabricated and measured for further verification, which has a good broadband radar absorbing performance in
1.7～5.7 GHz.
