Mode Excitation of Plate by CMA

摘要

In this paper, we discuss excitation method and its characteristics of eigenmode on the plate. First, By using CM analysis on the plate, we confirmed that changes of eigenvalues and weighting coefficient due to the feeding structure and slot length. Moreover, comparing the standard deviation in the main 6-mode in delta-feed, we found that the single port feed is closer to the eigenvalue of the plate. Also, we found that each mode is selectively excited by the length of the slot and the feed structure.
