A radio-wave anti-reflection sheet has a substantially non-tacky first major surface and an opposing substantially tacky second major surface and includes a first polymeric foam layer disposed between the first and second major surfaces, and a second polymeric foam layer disposed between the second major surface and the first polymeric foam layer. The first polymeric foam has a thickness from 0.05 to 3.0 mm and a density from 0.20 to 0.90 g/cm3. The second polymeric foam layer has a thickness from 0.05 to 3.0 mm and a density greater than 0.10 g/cm3 and less than the density of the first polymeric foam layer. A tape includes the radio-wave anti-reflection sheet disposed on a release liner. A vehicle member includes a multilayer substrate and the radio-wave anti-reflection sheet disposed on the multilayer substrate.
