Description
Summary:In this work, a novel experimental validation of characteristic mode analysis (CMA) is proposed using reverberation chamber measurements. Using the modal weighting coefficient formulation based on the magnetic moment and modal H field obtained from solvers, the total radiated power (TRP) is calculated. This TRP is compared with the TRP obtained from the reverberation chamber measurements. A good correlation between the simulation and measurement was achieved for a simple rectangular plate of size 15 cm × 8 cm with an error of less than 4 dB.
