Summary:
In this paper, a relatively simple modification is presented, regarding the antenna constellation for wave field synthesis in Over-the-Air test set-ups in anechoic chambers. Through the use of small vertical arrays, the effective volume of the test zone has been increased with respect to the shape of the emulated wave fronts. Also, the decay of the emulated field over distance has been reduced. Passive networks can be used for exciting the array elements, meaning that no additional channel emulators are needed.
