Abstract

This paper presents an experimental study evaluating the efficiency of various isolation techniques for antenna arrays in the D-band. The influence of antenna polarizations, the distance between the arrays, presence of absorbing materials and metal shield on isolation is studied. The study demonstrates that isolation of up to 80-85 dB between transmitting and receiving antenna arrays in the D-band can be achieved.
