“…Since the absorber tiles are 60 cm × 60 cm in size, we can use a two tile length chamber, i.e., make the chamber length to be L = 1.2 m. According to [20], to have an incidence angle less than 60 • in the main specular point, the chamber width should be at least W = L/2 = 60 cm, which in our case corresponds to use only one absorber tile. Equivalently, the chamber height was also selected to be equal to the width H = W = 60 cm.…”

Design of an Anechoic Chamber for W-Band and mmWave

In this paper, we describe the design of an electrically large anechoic chamber for usage on millimetre-wave bands. Ansys Savant sotware was used to perform a simulation of the chamber, using physical optics coupled with uniform theory of diffraction (PO/UTD). Moreover, a method based on an open waveguide probe is described in this paper to obtain the electrical properties of the RF absorbers at millimetre-wave frequencies. Two different source antennas were simulated in this work and the corresponding quiet zones predicted. The largest quiet zone was 30 m m × 30 m m × 50 m m , for a chamber size of 1.2 m m × 0.6 m m × 0.6 m .
