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 the transmission line to get the more right result. However, this formula has a reasonable accuracy.

The calculation formula is taken from the ARRL Handbook For Radio Communications: • 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 Proposed below calculator uses this formula with sizes transformed in the metric system:

ENTER THE INPUT DATA:
 b = mmcm – The length of the conductor h =  mm – The height of the conductor d =  mm – The diameter of the wire

RESULT:
 L = nHμH – Inductance
