Inductance as a straight wire over the plain with one grounded end:

Inductance is used on UHF. Of course, we have to present this inductor as a segment of a long-line to get more right result. However, this formula have a reasonable accuracy.

Calculation formula is taken from the ARRL Handbook For Radio Communications:

straight wire over the plain with one grounded end formula

  • L = Inductance µH
  • a = radius of the wire in inches
  • b = length of the conductor parallel to the plain in inches
  • h = height above the plain in inches
straight wire over the plain with one grounded end

Proposed below calculator uses this formula with sizes transformed in the metric system:

 


ENTER THE INPUT DATA:
b =  – The length of the conductor
h =  mm – The height of the conductor
d =  mm – The diameter of the wire
Calculate
RESULT:
L =  – Inductance
Clear all

Only on K7MEM's site calculation follows the same formula, but has an error: calculator uses wire diameter instead of radius.
