Modern radar technology has further developed functions such as electronic reconnaissance, friend or foe identification, electronic interference, accurate guidance and the like through early detection, fire control, weather and navigation functions. The antenna housing working frequency is also developed from a single frequency to a wide frequency, and reaches a multiband full frequency band.
The millimeter wave generally refers to a part of the electromagnetic spectrum with a frequency of 30 to 300GHz and a corresponding wavelength of 1 to 10 mm. Compared with the traditional radome with decimetric waves and centimeter waves, the radome with millimeter waves has higher requirements on the aspects of structure, materials, performance, process technology and the like.
CN108274879A discloses a preparation method of a high-frequency wave-transparent sandwich structure composite material 5G radome, wherein the radome is composed of an inner skin, an outer skin and a core layer material, the skin material is made of a glass fiber reinforced cyanate ester modified epoxy resin composite material, and the core layer material is an aramid honeycomb core. The panel wave transmission rate of the antenna housing under the working frequency of 28GHz is more than 90%, namely the antenna housing has excellent wave transmission performance under a single frequency, and the existing antenna housing does not only receive a signal of one frequency, but also needs to receive signals of a plurality of frequency bands and high bandwidth at the same time.
CN104103898A discloses a high-wave-transmission low-RCS (radar cross section) radome, which comprises wave-transmission interlayer structure thin layer units, wherein each wave-transmission interlayer structure thin layer unit is fixedly connected to a metallized flange surrounding frame area coated by carbon fibers to form a wave-transmission window, a laminated structure in a layer-by-layer coating mode is adopted, the outline of the wave-transmission area of the radome is in a rhombic shape or a streamline shape similar to almond kernels, the radome is installed on a low-RCS carrier platform for simulation or test, and the level of RCS of the radome cannot be truly reflected by directly simulating or testing the radome, wherein each wave-transmission interlayer structure thin layer unit is in a three-layer structure and is respectively a laminated structure formed by coating quartz fiber glass cloth, PMI foam and quartz fiber glass cloth from top to bottom. The radome only satisfies high wave-transmitting rate, and the wave-transmitting rate under multiple frequency bands and high bandwidth is not ideal.
