Abstract

The invention relates to a structure capable of being used for Ku and Ka dual-band wave transmission. The structure comprises skin layers and an FSS layer; the FSS layer is bonded between the two skinlayers; the structure has the advantages that the Ku and Ka dual-band wave-transmitting function can be achieved, electromagnetic wave polarization insensitivity is achieved, the stable wave-transmitting characteristic is achieved when the incident angle of electromagnetic waves in the wave-transmitting band ranges from 0 degree to 60 degrees, the low-band electromagnetic wave reflecting functionis achieved, and the stealth performance of a radar is improved.

Description

technical field [0001] The invention relates to the technical field of radar wave penetration, in particular to a structure that can be used for Ku and Ka dual frequency band wave penetration. Background technique [0002] The frequency-selective surface structure has a significant effect on the suppression of radar antenna electromagnetic scattering. On various platforms equipped with radar sensors, special frequency selective surface structure radome is used to improve the low detectability of the radar system. The traditional radome often only considers the wave penetration performance of a single frequency band, but now the new radar Communication antennas in two frequency bands are often installed, so the matching radome should ensure good passband characteristics in these two frequency bands, but the existing radome transmits large-angle incident electromagnetic waves in the Ku and Ka frequency bands. Poor stability. [0003] Therefore, to address the above deficienc...
