Reverberation Chamber for Antenna Measurements: Modeling Using Method of Moments, Spectral Domain Techniques, and Asymptote Extraction

Journal article, 2006

Large reverberation chambers (RCs) have proved to be useful for measuring the performance of small antennas and terminals for wireless communications, and it is therefore important to be able to model them numerically to control accuracy. This paper describes a method of moments approach for analyzing wire antennas and other metallic objects in a large RC. The RC is treated as a rectangular perfect electric conducting cavity, and the Green's function is constructed by using a spectrum of plane waves and imaging combined with periodic boundary conditions. The code has been validated by comparison with measurements and other computer codes. © 2006, IEEE.
