Antenna height scan for minimizing EUT emission measurement uncertainty in fully anechoic chambers above 1 GHz

Our aim in this research work is to propose a methodology on receiving antenna height scan in the fully anechoic room (FAR) to minimize uncertainty in obtaining maximum emission of equipments under test (EUT) that have multilobe radiation patterns at higher frequencies. An EUT with complex slots is measured. The radiation emission for five antenna heights from 1 m to 1.8 m with a 0.2 m increment are experimentally measured and characterised over the 1 GHz - 15 GHz frequency band for both vertical and horizontal antenna polarizations. Radiation patterns of the EUT are presented
