This paper presents a design method of broadband radar absorber (RA) combing together the features of frequency selective surfaces (FSSs), subwavelength hole array and magnetic absorbing sheet.The absorber is constructed of a periodic array of square conducting patches embedded into a magnetic absorbing substrate perforated with circular hole arrays and backed by a metal ground.The absorption characteristics of the magnetic absorbing substrate are tuned and improved by means of perforating holes and embedding FSSs.After optimizing the dimensions of holes and FSSs, the RA with a thickness of 2.4 mm achieves a reflection coefficient <-10 dB from 6.3GHz to 17.3GHz, which is nearly 3.6 times the bandwidth of the magnetic absorbing substrate.Meanwhile, the weight of RA decreases by 15 % due to the hole perforation, and the reflection coefficient is insensitive to incident angle from 0°-30° for both TE and TM polarization.
