Design and Testing Radome for D-band applications

Abstract

The paper presents results of characterization of dielectric properties of several commercial radome materials in D-band. It is demonstrated that there are commercial radome materials on the market already today which can be used for D-band radome. A multilayer radome based on selected materials Preperm RS260 and Rohacell HF is designed and tested. The radome demonstrates transmission losses not higher than 0.75 dB in the frequency band of 130 – 165 GHz. Usage of the radome in a combination with a D-band antenna array is studied.
