Summary: A new method is proposed to estimate the AM-RCS of a large-scale array antenna by improving the SPMM to consider mutual coupling and edge effects, thereby increasing accuracy. The AM-RCS of a large-scale array antenna is estimated by deducing it from the subarray, with the accuracy of the method improving as the subarray size increases. Verification using microstrip linear array and Vivaldi planar array shows that the proposed method has lower calculated error and memory requirement compared to the reference method.

Summary: This letter presents a fast and efficient metasurface design approach using ray-tracing theory to guarantee wide-angle low scattering and wideband RCS reduction. By engineering the proposed metasurfaces to exhibit a diffusive parabolic phase distribution, the reflected energies are redirected over all directions at frequencies other than the center frequency. Numerical and experimental results demonstrate the effectiveness of the designed metasurfaces in achieving significant RCS reduction over a wideband frequency range.

Summary: This paper proposes an ultrawideband planar monopole array antenna with excellent stealth performance by using a combination of traditional copper film and novel phase transition film vanadium dioxide (VO2). By carefully designing the antenna shape and using an innovative combination of VO2+Cu films, the tradeoff between radiating efficiency and reducing radar cross section (RCS) is optimized, resulting in a decreased gain of only 0.4 dBi and a reduced monostatic RCS of about 9 dB.

Summary: In this study, a new design of an S-shaped antenna with additional slits and slots is presented, and its performance is enhanced. A parametric study was conducted using two commonly used dielectric materials, with RO4003C outperforming FR4 in terms of high-frequency suitability. The antenna was fabricated using RO4003C and showed good agreement between simulated and measured results. Operating at resonant frequencies of 10 GHz and 17.65 GHz, the antenna is suitable for both X and Ku bands. It exhibited better gain at 10 GHz, with a measured gain of 6.3 dB. A comparative table further demonstrates the antenna's superiority in terms of gain and compactness compared to other X-band antennas.
