The paper presents results of design and testing of a single material multilayer (SMML) radome for applications in D-band. The two-layer radome is designed and tested. Both layers are fabricated of a single plate of PREPERM RS260 material. The first layer is a homogeneous layer, and the second layer has a pattern of cavities configured to decrease an effective dielectric constant of the material. The radome demonstrates transmission losses 0.15 dB at the frequency 150 GHz. It has a wider bandwidth than a wavelength radome fabricated from the same material. Possibility of realization of a single material multi-layer wideband radome is studied.
