Abstract
Astrophysical experiments dedicated to the study of the Cosmic Microwave Background are in needs of very welldefined beam shape in order to get an accurate re-construction of the anisotropies power spectrum. These beams have tobe carefully designed, but also properly characterised. Some of these instruments will be located in a cryostat for whichfilters and windows are necessary, and the effects of these additional optical components on the beam shape need to betaken into account. We present here, measurements of such effects on the co- and cross-polarisation radiation patterns ofcorrugated horns using a Vector Network Analyser
