RF Characterization of Latex Coated Pyramidal Absorber

Abstract

We present a test procedure and results comparing RF performance of traditional pyramidal absorber to that with latex coating. Measurements are performed from 4-12 GHz, but the same measurement methodology can be applied other frequency bands. Absorber with protective coating is being used in place of traditional absorber for outdoor antenna measurement facilities to reduce degradation of the absorber performance in harsh environments. Knowledge of the RF performance characteristics of coated absorber is especially necessary when it is used to replace uncoated absorber in an operational antenna measurement facility. The effect of the latex coating on the uncertainty associated with the absorber performance is examined. Measurements are performed using a simple measurement setup based on a vector network analyzer and broadband horn antennas. Results from mono-static and bi-static measurements are presented.
