Abstract
A full wave analysis of the propagation characteristics of a through hole (or via hole) carried out using the finite-difference time-domain (FD-TD) method is presented. Results are compared with measurements from a physical model. The effects of rod diameter and microstrip connecting angle are examined. The computer scattering parameters (S-parameters) of a through hole show excellent agreement with measured results from DC to high frequencies and in the time domain responses. It is also shown that at high frequencies radiation is at a significant level and rod diameter and microstrip connecting angle strongly influence the propagation characteristics of a through hole.<>Keywords
