Abstract

Approaches to estimate the current distribution on EM source such as antennas and printed circuit board (PCB) by measuring the near-field distribution are demonstrated. These approaches include the matrix inversion method and sampled pattern matching (SPM) method. All of these approaches require accurate near-field measurement and field-current inverse algorithm. Experimental results are presented and compared with the numerical results, confirming the accuracy and performance of these methods.
