Using the method of combination, we have made a communicational band (0.8 GHz to 3 GHz) dual-directional metamaterial absorber. Simulation and experimental results show that the absorber to the incident electromagnetic wave of different polarization and wide-angle has three stable absorbing bands(2.04, 2.34, and 2.65 GHz), and the absorptions can reach 92.3%, 95.3% and 94.7% respectively. This kind of absorber is very simple in design, having strong flexibility, perfect absorption, and easy processing, which works in a communicational band (0.8 to 3 GHz) so that it provides a new idea on electromagnetic shielding and anti interference.
