Design of novel broadband absorber based on resistive film

  •   Objectives   In order to improve the performance of traditional absorbing materials, a high-absorptivity broadband absorber is designed.
      Methods   The absorber consists of a resistive film, dielectric substrate and metal ground plate. The element unit of the resistive film is composed of a Jerusalem cross unit and outer square loop.
      Results   The simulated results indicate that the absorption of the designed absorber is more than 90% in the frequency range of 2.9–5.1 GHz, and an absorptivity peak of 99.4% can be achieved. Absorption performance can also be maintained in wide-angle cases and polarization-insensitive cases.
      Conclusions   The absorber proposed in this paper has significance for the design and application of broadband absorbers.
