Abstract

In this paper, a new type of planar Goubau line (PGL) for millimeter- and submillimeter-wave applications is proposed for use in wideband integrated circuits. The configurations of these modified Goubau lines are examined and the parameters are provided. The performances of these lines are studied in detail. Characteristics of lines with different dimensions are calculated and displayed. Comparisons with other types of transmission lines are also performed. © 2004 Wiley Periodicals, Inc.
