Abstract
The present invention relates to a transmission line in which a physical value of an inductive element can be changed in various ways while minimizing a size. The transmission line of the present invention includes a transmission unit, a ground unit and inductive elements. The inductive element connects the transmission unit and the ground unit, and has a predetermined pattern. The inductive element is provided between two surfaces of a substrate. According to the present invention, a physical value of the inductive element, in particular, an inductance value can be changed in various ways while not increasing an overall size. Accordingly, a transmission line can be designed freely according to its application.
