I am designing a loop antenna and would like to calculate the inductance. The radius of the loop is 6.67 centimeters, the radius of the wire is .42mm (#26 awg) and has 57 turns.
Using the following formula
L =N^2*R*mu_o*mu_r*(ln(8R/r)-2)
where N=turns, R=loop radius and r=wire radius. From this and assuming copper wire is roughky the same as air in terms of permeability I get a result of 1.4 mH.
To mee that seems like it is
orders of magnitude too large. Can some please verify that my calculations are correct or if theu are not provide me with the correct equation?
