We
present an UHF prefect metamaterial absorber by combining coupling lines and
fractal lines with very small unit cell. The proposed absorber consists of
surface metal structure and metallic background plane, separated by a
dielectric substrate and air. Simulation results show that the absorber has
absorption peak at 442MHz with 99.73% absorptivity. The ratio between lattice
constant and resonance wavelength is 1/68, significantly less than the existing
absorber. According to the absorption mechanism of proposed absorber the design
principle is introducing in detail. Moreover, the absorption peaks remain high
with large angles of incidence for both TE and TM polarizations. Due to the
small ratio, it can be widely used in radiation suppression for microwave relay
communication such as mobile communication and wireless network by changing the
parameters of structure.
