Microstrip Inductor Calculator

This calculator computes the inductance of a microstrip etched on a PCB, which according to the ARRL handbook is:

L= 0.00508*b*(ln(2*b/(w+h))+.5+0.2235*(w+h)/b)

where:

w is width of the strip in inches,
b is the length in inches,
h is the distance between the strip and the ground plane, and
L is inductance in uH.
