“…The working principle of the checkerboard surfaces is that the scattering field of the adjacent checkerboard blocks is cancelled because the amplitude is the same and the phase difference is 180° [1][2][3][4][5][6]. A wider 10 dB RCS reduction bandwidth of 60% is obtained by combining two different types of electromagnetic band gap (EBG) structures for the square and hexagonal checkerboard surfaces [1].…”

Polarization conversion metasurface (PCM) with wide operating band and high polarization conversion ratio is proposed for antenna radar cross-section (RCS) reduction. A 3rd-order quadrate fractal structure (QFS) is designed as the PCM element that the polarization conversion ratio is greater than 80% from 10.45 GHz to 32.15 GHz (relative bandwidth of 101.9%). The PCM is applied in the RCS reduction of microstrip antennas by chessboard-like arrangement on the antenna. The performances of the proposed PCM and antenna are studied by measurement and simulation. The results show that, with the radiation performance hold, the monostatic RCS of the proposed antenna is obviously reduced from 8 GHz to 28 GHz which completely covers the operating band of the antenna.

“…Traditional ways to enhance the antenna gain are mainly divided into two ways, changing the antenna structure and adopting antenna arrays [4], [5], which would suffer from design complexity, high cost, power losses in the feeding network and such similar problems, and these will also result in the raise of the target RCS which is harmful to their stealth properties. Therefore, the realization of wideband high gain and low scattering antenna has been a major problem [6].…”

“…Theoretically, once an antenna can work in the operating frequency band of the EBGs, the performance of the antenna could be improved by using an EBG substrate. However, due to the ease with which EBG cells cause frequency shifting and increase of backscattering, they should be carefully arranged . In this article, a dual‐band H‐shaped antenna based on a dual‐band pinwheel‐shaped slot EBG substrate is proposed.…”

“…More recently, electromagnetic band-gap (EBG) structures have been incorporated into the design to improve the performance of patch antennas. [5][6][7][8][9][10][11][12][13][14][15] As a kind of high impedance surface, the EBGs could be applied to suppress the propagation of the surface wave within the bandgap frequency range. 5,16 Accordingly, the configurations of the antennas do not need to be redesigned.…”

Generally, the surface wave of an antenna can be suppressed by integrating the electromagnetic band‐gap (EBG) structures. However, to achieve this effect, the EBG cells must be reasonably designed, otherwise it may lead to performance degradation instead. In this article, a dual‐band pinwheel‐shaped slot EBG structure is proposed. When applied to a patch antenna, defects are introduced into 3 rows of the EBG unit cells. The proposed antenna, incorporating EBGs designed with structural defects, to radiate at 4.9 and 5.4 GHz is simulated and tested. The measured results show that the −10‐dB bandwidth of the proposed EBG antenna is extended by 41% and 25.4% at low frequency and high frequency, respectively. In addition, the peak gain of the proposed EBG antenna is increased by 2.44 dB at 4.9 GHz and 2.86 dB at 5.4 GHz with >40% efficiency. When compared with the periodic EBG antenna, this antenna is more effective. Thus, these experimental results show that the performance of the EBG antenna can be improved by interrupting the periodicity of the EBGs structures.
