Abstract

The conditions of measurement of radio disturbance emission are defined in EN 55016-2-3 standard. It defines the detailed requirements of the measuring system and the methodology of the test. In case of the measurement up to 1 GHz the antenna height scan is required but there is no regulation regarding the antenna tilt in current edition of standard. As a result most laboratories perform measurements of radiated emission with a fixed antenna angle of 0∘ -the antenna is located in parallel with the ground plane despite the actual height. Knowing that the antenna inclination angle in relation to the emission source affects its characteristics, it can lead to omit the measurement configuration at which the measured field strength is the highest. The article investigates the influence of receiving antenna inclination angle on measurements of radiated disturbances from a reference emission source and real TV-set.
