A Novel Design Microwave Anechoic Chamber For Antenna and Microwave Laboratory

Microwave absorbers are important part in antenna and microwave laboratory which determines antenna and microwave truly exact and precise results. For this issue designing an absorber is a principal need in such labs. In this paper, a X-band (8 -12 GHz) pyramidal shaped absorbers is designed that made of urethane covered by carbon, that has 0.6 Siemens/m bulk conductivity and 0.3 dielectric loss tangent and a FSS made of an array of thin layer of copper patches deposited on a grounded dielectric. The design was compared between some designs and optimized by computer simulations using Ansoft HFSS software to calculate S11 and S12 parameters.
