Efficient setup for the measurement of transmission-coefficients with a single-room anechoic chamber

This paper describes a new setup for the measurement of transmission coefficient of materials. The proposed setup is a cheap and efficient way to obtain a good isolation between the transmission and reception antennas with a single room anechoic chamber. The dynamic range is better than 60 dB between 3 to 7 GHz and better to 40 dB in the range 0.7–3 GHz. Moreover, this measurement bench is easy to install and does not require modifying the configuration of the absorbents of the anechoic chamber. It is a excellent technique to measure the performances of Frequency Selective Surfaces (FSS).
