Abstract
A low-profile, metamaterial absorber with wide angles of incidence and polarization insensitive behaviour is reported in this paper. The proposed structure consists of a L shaped resonator with Pythagorean tree fractal structure capable of exhibiting near unity absorption in three frequency bands. The proposed structure provides absorption of more than 90% over three frequency bands namely 5.9GHz, 11.9GHz and 15.01GHz respectively. Over these frequency bands the structure remained polarization insensitive upto 70 degree and angle insensitive upto 30 degree.
