Polarization Error in Fieldstrength Measurements

Especially in EMC testing, the fields to be measured are, however, far from being linearly polarized and the plane in which the field vector oscillates is not necessarily perpendicular to the direction of propa­ gation. in such instances, a measurement carried out according to the usual schemes, valid for linear po­ larization, results in an error, the value of which depends on the polarization mismatch between the fi­ eld and the antenna.
