Abstract
A coupling device with electro-magnetic compensation is provided. The coupling device includes a first substrate having a first signal line on a top surface of the first substrate and a second substrate having a second signal line on a top surface of the second substrate connected together with a bottom surface of the first substrate wherein the second signal line couples with the first signal line by a plurality of electrical-conductive through holes. One side of the first signal line lies a capacitor device parallel connected to a ground and the capacitor device plays the role of adjusting the amount of return loss, isolation capacity, and coupling effect so as to have transmitting speeds in first and second signal lines remain substantially the same and superior high frequency characteristics.
