When it is within half a line width away, the impedance drops by 1 [OMEGA], and then drops faster as the ground trace gets closer.
E], and since [Beta] decreases almost linearly with increasing frequency, the input impedance drops with frequency.
In the tightest coupled differential microstrip, with a spacing equal to the line width, the differential impedance drops only about 10% from the differential impedance when the traces are far apart with no coupling.
