Antenna radiation pattern measurements are typically performed in anechoic chambers which are expensive to buy and inconvenient to rent from external facilities. This paper investigates the use of a reverberation chamber for antenna radiation pattern measurements due to its significant cost reduction compared to anechoic environments.
chamber wall to improve the quietness of the anechoic chamber. Long pyramid absorber used for low-frequency anechoic chamber tends to droop with age. Twisted pyramid structure has been used to improve the mechanical strength. The pyramid is “twisted” by 45 with respect to the base (see Fig. 1c).
