A light‐weight and wideband X‐band absorber employing a resistive silver nanowire (AgNW) film is presented. One unit of the absorber is composed of a cross‐shaped AgNW resistive film and a conducting plane separated by a 7.5 mm ( λ 0 /4 at 10 GHz) Styrofoam ( ε r = 1.03) layer. The used surface resistance of the film is 42 Ω per square. The 90% absorption bandwidth of the absorber is 80% from 6 to 14 GHz with a near complete absorption at the centre frequency of 10 GHz. Besides, it is also shown to be polarisation‐insensitive.
