Fractal Absorbing Body Design and Its Application in Microstrip Antenna
摘要
Abstract
A metamaterial absorber based on hilbert fractal structure is designed with miniaturization,slim,high absorptivity and no surface ullage layer.Its unit size is only 0.071λ,the thickness is about 0.02λ and the absorber can exhibit absorption of 99.3 %.It is conformed on microstrip antenna to preparation of a novel metamaterial antenna.Compared with the conventional microstrip antenna,the proposed antenna has a obvious monstatic and bistatic radar cross section reduction at the working frequency band.the greatest decrement can amounted to 7.2 dB,while the radiation performance is kept,which proves that the absorber had an excellent absorptivity.The simulation and measured resultes are in good agreement,indicating that the absorbing body can be applied to microstrip antennas to achieve in-band stealth.关键词
