What is Electrical Length?
The RF/microwave literature specifies that micro strip line is 43 degree at frequency of 5GHz. What does this mean? Let us understand this in detail below.
Electrical length =E= (l/Lambdaref) * 360 degree
E= T * Fref * 360 degree
This indicates that a line which is 1 ns long has an electrical length(E) of about 360 degree at frequency(Fref ) of 1GHz.
