Abstract-A composite wideband absorbing material (WAM) covering dual bands is designed, to reduce the in-band radar cross section (RCS) for broadband antenna in this paper. The upper layer is a traditional absorber while the lower one is a dual-band frequency selective surface (FSS), which is formed by a square ring and an improved Jerusalem cross structure. The absorbing band has been broadened to 112% compared with the magnetic sheet without FSS. Over C and X bands, the absorption rate is over 90%. By using the FSS-based WAM as the ground plane of a Vivaldi antenna, substantial RCS reduction is obtained from 2-18 GHz. Moreover, the RCS is reduced remarkably over −80 • -80 • incident angles except for minority angles, with the radiation performance preserved at the same time.The experimental results are in good agreement with the simulated ones.

“…A suitable shaped bandpass radome placed in front of the antenna [2][3][4] or used as the metallic ground of the patch antenna [5] can significantly reduce the out-of-band RCS of any antenna. Besides, the band-stop FSS can be used as backing reflector to reduce the out-of-band RCS [6]. Radar absorber material (RAM) can absorb the electromagnetic wave and convert the energy into heat over a wide frequency band [7][8][9].…”

Abstract-A new method for reducing the in-band radar cross-section (RCS) of a patch antenna within its operating frequency is presented. This method is based on the utilization of band-pass frequency selective surface (FSS) consisting of non-resonant constituting elements. The main novelty of this method is that it allows for the use of an FSS structure to reducing the in-band RCS of antennas. To validate the proposed method, a low RCS patch antenna resonating at 5 GHz is designed using this method. The simulated results show that the largest RCS reduction is about 15 dB at 5 GHz. A prototype of the proposed antenna is fabricated and tested in an anechoic chamber, and good agreements between the measured and simulated results are demonstrated.

“…There are many reports on the application of conventional radar absorbing material (RAM) and frequency selective surface (FSS) on RCS reduction [4][5][6][7], but the bandwidth is not wide enough when FSS or RAM is used separately. Studies show that the combination of RAM and FSS can expand the bandwidth of RCS reduction effectively [8][9][10].…”

Abstract-A novel Quasi-Yagi antenna with low radar cross section (RCS) is proposed in this paper. By using arrow-shaped Koch dipoles as the driver and director and cutting the ground of the antenna, the RCS can be reduced in the operating band of 5 GHz-8 GHz when the incident wave is perpendicular to the antenna plane. Wideband radar absorbing material (WRAM) with frequency selective surface (FSS) is devised to replace the metallic reflect plate of the antenna to reduce the RCS in the maximum radiation direction. The average RCS reduction of the antenna in the frequency band of 3 GHz-12 GHz is 8.0 dB. The simulated and measured results show that there is a considerable RCS reduction of the Quasi-Yagi antenna with WRAM, and the radiation performance is preserved at the same time.
