With reduction of the trace height above the PCB ground plane, the radiated emission is
reduced in the whole frequency band by the factor
|(a) Placement of Trace A and Trace B.
The trace width is 0.2mm, the trace height above the ground plane is 0.65mm. A
10mV voltage source with an impedance equal to the characteristic impedance of the trace
drives the trace which is terminated with a 10pF capacitance.
|(b) Radiated power. Width of Trace B: b=0.49mm.||(c) Radiated power. Width of Trace B: b=2mm.
