Abstract-In this paper, a novel microstrip antenna array with reduced radar cross-section (RCS) is proposed and studied. We define that the grazing angle θ of radar incident wave ranges from 80 • to 90 • . Under the condition that the incident wave is in grazing angle, a microstrip antenna designed by the techniques of miniaturization and ground-cut slots is given firstly. Compared with a traditional rectangle microstrip antenna, the RCS peaks of the proposed antenna are efficiently controlled over the frequency range of 4∼16 GHz. Based on the design above, the proposed antenna is chosen as an element to design a 2 × 2 antenna array. Analysis and optimization of the arrangement of the array is made to achieve more RCS reduction. The measured results of radiation performance accord with the simulated ones, which indicate that the proposed method is feasible.

“…In addition, the potential application of metamaterials in stealth technology also becomes a hot topic of current research [17][18][19][20], where RCS [21][22][23][24] is the main consideration in the design of military platforms. There are two different solutions proposed for RCS reduction using metamaterials: cloaking devices [25] and metamaterial absorber.…”

Abstract-A metasurface for Radar Cross Section (RCS) reduction is proposed. The surface is composed of the same type of metamaterial units with different geometric dimensions, leading to various reflection phases under the incidence of plane waves. By carefully choosing the phase distributions, diffusion will be produced for the reflected waves which may redistribute the scattering energy from the surface toward all the directions, and hence it can be applied as the coating of metallic targets with ultra-low RCS. Both the simulated and experimental results have validated the proposed method.

“…Radar Cross Section [1][2][3][4] reduction has received a lot of attention for many years, being the military applications (stealth technology) among the more attractive ones. The aim is the same in all the scenarios: to reduce the scattered electromagnetic field when illuminating the object-of-interest by an incident wave.…”

Abstract-A thin Artificial Magnetic Conductor (AMC) structure for Radar Cross-Section (RCS) reduction applications is presented. The manufactured prototype, which combines two unit-cell metallization sizes, presenting two resonant frequencies, shows broad AMC operation bandwidth, polarization angle independency, and its angular margin when operating under oblique incidence is also tested. It is shown that significant RCS reduction can be achieved with the proposed AMCs combination even if a 180 • phaseshift between reflected waves is not met. Two designs are considered: the already mentioned design combining AMCs with overlapped frequency bands and the second one combining Perfect Electric Conductor (PEC) and AMC surfaces. A comparison between these two designs regarding RCS reduction, supported by measurements in an anechoic chamber, is presented.
