Web24 de jun. de 2024 · Abstract: Geometric approximation errors of periodically distributed surface facets of cable-network reflector antennas can result in grating lobes undesired in some space missions. As the surface is shaped by the tensioned flexible cable-network structure, the electromagnetic (EM) and structural parameters are highly correlated, and … WebI. Introduction Traditionally, reflector antennas are designed for limited scan. A symmetrical parabolic reflector with fD4.4 can only scan d5 beamwidths (BW) with less than 2 dB loss [ 13.If the reflector diameter is 1,0oO h, the f5 BW scan corresponds to only &OS0, which is a very narrow field of view. In some future applications, the antenna requirements will be …
