Abstract

Microstrip lines and tracks of Printed Circuit Boards (PCBs) have definitive effects on the
electromagnetic wave induction and interference on boards. In this paper the effect of changes in
the physical characteristics of conductive lines and PCBs was simulated three dimensionally using
Finite Difference Time Domain (FDTD) method. The length and width of a microstrip line and
thickness of PCB are among parameters that variation effects of which are presented using
simulation. High power Electromagnetic radiation effect on a transistor amplifier is also
investigated by introducing corresponding electromagnetic equations into the simulation software
using BJT GP model
