What is the meaning of electrical length in microstrip line?

Hello,

Wikipedia explains it very nicely.

Thanks

Hi

it is a phase shift (in degrees) the line introduces at a given frequency.

Electrical length will be different from physical length, because the velocity of signal in a medium will be less than the velocity of light in free space.

Thats close but the velocity of light doesnt enter into the equation :)
your statement rephrased....
"Electrical length will be different from physical length, because the velocity of an RF signal in a medium will be less than its velocity in free space"

Anyway Nafah, just read the link given to you by MobiNaz and all will be explained :)


cheers
