Design of Frequency Selective Radome based on Pyramid Lattice Sandwich Structure

Abstract

The organic combination of sandwich structure and frequency selective surface technology can provide strong support for the design of lightweight and high-strength radome. This paper optimizes the structural media parameters on the basis of the existing pyramid lattice structure, and designs a frequency selective surface, which is combined with the lattice structure to form a lattice structure frequency selective radome, which forms a pass-band at 2.41GHz–3.17GHz, 8GHz–12GHz forms a stop band, and the pass-band transmission rate is over 90%, and the stop-band attenuation is less than −10dB. In this paper, the patch antenna and frequency selective radome are jointly simulated to verify that the frequency-selective radome designed in this paper meets the design requirements.
