Design of compact high-transmission feed support radome for deployable reflector antenna

In response to the application requirements of mobile carrier platforms for deployable reflector antennas, this paper proposes a novel compact high-transmission feed support radome structure based on composite materials. The radome structure adopts A sandwich structure with a honeycomb core in the middle and quartz hydrogel outer skins. The radome body has a conical cylinder shape, with both ends connected to the feed and the center body of the reflector through metal flanges. To obtain high transmittance and mechanical structural performance of the radome, genetic algorithm was used to optimize the thickness parameter of each layer. The simulation results show that this compact feed support structure has a small impact on the radiation performance of the deployable reflector, with a transmission rate of over 80% at LS band, and also has excellent mechanical structural performance, the deformation of the radome is within 1mm under extreme load conditions.
