一种基于接收天线阵列的宽带吸波层设计
A wideband absorber screen design method based on receiving antenna array
摘要
Abstract
This paper designs a method of wideband absorber screen based on the receiving antenna technique.A dual-polarized magneto-electric dipole antenna is selected as original model according to the similarities of working principle between the receiving antenna and absorber.The antenna is improved by the wave-absorbing mechanism to the original absorber.The geometric parameters of the absorber cells are simulated and optimized by the HFSS software to accomplish the thin profile and broadband absorber screen.The measured results show that the finite 6 × 6 array absorber screen provides a 10 dB RCS reduction over the entire frequency range of 1.54-3.31GHz,which is equivalent to a relative bandwidth of 73％.The thickness of substrate is below 1/9 wavelength of the center frequency in free space.The absorber screen can also be used in dual polarization because of its symmetrical property.关键词
