英文摘要
In this paper, a novel wideband absorber for radar cross section (RCS) reduction is presented. Unlike previous absorber designs that use multilayer lossy materials, this study proposes a design based on a planar antenna array that adopts a bowtie dipole structure as the unit cell. Since the desirable features of a wide operation band and a simple design of a bowtie-shaped antenna, the proposed design adopts a bowtie dipole with a lumped resistor as the unit cell of a twodimensional periodic array. The complete design procedure is explained through the design examples. The measurement result shows that the bandwidth of the design exceeded 81% (RCS reduction > 10 dB) when the thickness is about 11% of the free space wavelength at the lowest operation frequency.
