Abstract
Recently, printed circuit boards with multi-layer are increasing since advanced technology makes electronic circuits high-density. Then, a number of vias to connect each layer are used and slots are put on a ground. The existence of slots is issue for circuit designs in future. There is the Transmission Line (TL) method which can calculate with short time as an analysis method of transmission line. It is important to consider the effects of slots in by the TL method. In this paper, when the ground slot exists asymmetrically underneath a microstrip line, we analyzed the propagation characteristic and characteristic impedance of a microstrip line with the ground slot in PCB using TL method. In addition, we show the validity of the TL method by using the FDTD method and measurement.
