Abstract

Abstract:

In order to increase computing speed, MOM formulations including closed-form spatial domain Green’s functions are derived for geometry of microstrip. Based on loss substrate, radiation emission and interference suppression for signal lines are investigated. The results show that radiated power from a signal line with a shielding line is much less than that from a signal line without a shielding line. Therefore, in the EMC design of digital circuits, adding a shielding line to a signal line can effectively decrease spurious radiation.

Key words: radiation, method of moments (MOM), microstrip, printed circuit board (PCB)
