SHORT GUIDED-WAVE TRANSMISSION LINE EMPLOYING PERIODICAL 3-D CAPACITIVE COUPLING STRUCTURE AND ITS APPLICATION TO MINIATURIZED BRANCH-LINE COUPLER

摘要

PURPOSE: shortwave long transmission line improves the RF circuits of its bandwidth characteristic with the combining coupler minimized, utilizes periodical drive mechanism. ;CONSTITUTION: multiple ground planes are formed in semiconductor substrate or printed circuit board. Multiple are set to floor periodically or non-periodically (one). Floor is electrically connected to each other multiple bands. Form the ground plan between the line. The route will not be electrically connected to each other with ground plane. The route will not be electrically connected to each other with item. Dielectric is disposed in band and line. ;The 2010 of copyright KIPO submissions
