Manufacturing and environmental uncertainties can significantly affect the electromagnetic (EM) performance of antenna-radome systems, leading to degradation in key indicators such as reduced transmission coefficient, increased boresight error, and shortened radar detection range. To efficiently and accurately quantify these effects, this study …

As the most precise interval analysis (IA) method in antenna/radome areas, convex-polygon-based IA suffers from the exponentially increasing computational complexity with antenna/radome discrete elements. This work presents a method to control the polygon vertex number to improve the efficiency. In the polygon …

This letter proposes a method for rapid analysis of the scattering characteristics of large-scale arrays based on the regional decomposition strategy. To achieve array analysis, traditional IDM methods use equivalent elements to characterize the mutual coupling effects between array elements. However, when …

Abstract A pattern-independent ultra-wideband frequency-selective surface (FSS) with a dielectric-metal-dielectric sandwich structure is proposed. Characteristic mode analysis indicates that the bandwidth of the excited modes increases with thickness. Then, a single-layer ultra-wideband FSS with ⩾ 80% fractional bandwidth (|S 21| ⩾ −3 …

In this study, a dual-band dual-beam shared-aperture reflector antenna based on a Cassegrain configuration is designed using a frequency-selective surface (FSS) subreflector. The antenna generates two shaped beams that operate at different frequencies and can spatially overlap. One beam contour can be …

Interval analysis (IA) has been proven a useful tool in radome tolerance analysis. Compared with the precise amplitude-phase-based IA (IA-AP) method, the real-imaginary-parts-based IA method (IA-RI) method is less accurate but much more efficient. In this work, correlation between the two IA …

This work proposes a linear array synthesis optimization method that maximizes the robustness against channel calibration and/or mutual coupling (MC) errors. The circular interval analysis (CIA) method is used to describe the interval power patterns of array antennas with errors (channel calibration …

A dual-polarized C-X-Ku-band frequency-selective rasorber (FSR) with a wide high-transmission passband is proposed in this letter. The proposed FSR is formed by cascading an lossy layer with inner-gate cross frame and a nonresonant lossless layer. This structure can simultaneously achieve polarization insensitivity, …

The performance of petal antennas is often hampered by deployment errors, a prominent form of error that has significant implications on radiation performance, and surface errors. Traditional calculation methods often overlook the relationship between errors on individual petals, thus leading to an …
