Abstract
An electrical circuit (400) includes a first input means (401) for providing an input signal, a first output means (406) for providing an output signal, and a transmission line device (405) electrically positioned between the first input means (401) and the first output means (406). The first transmission line device includes a first ground plane (409) disposed on a first dielectric substrate (402), a first conductive layer (405-1) enclosing a first area on a second dielectric substrate (403) that is positioned substantially adjacent to the first dielectric substrate (402). The transmission line device (405) further includes a second conductive layer (405-2) that encloses an area corresponding to the first area on a first major surface of a third dielectric substrate (404) that is positioned substantially adjacent to the second dielectric substrate. Lastly, an embedded ground plane (411) is disposed on a fourth dielectric substrate (412)that is positioned substantially between the second dielectric substrate (403) and the third dielectric substrate (404 ).
