Patent ID: 8643564

Claim:
A triplate line inter-layer connector having an electrical connection structure between a first triplate line in which a first feed substrate provided with a first feeder line and sandwiched between a first dielectric and a second dielectric is located approximately intermediate between a first ground conductor and a second ground conductor, and a second triplate line in which a second feed substrate provided with a second feeder line and sandwiched between a third dielectric and a fourth dielectric is located approximately intermediate between the second ground conductor and a third ground conductor, wherein: the first feeder line is provided on the first feed substrate to extend from an input end thereof at an edge of the first feed substrate to a first patch pattern which is formed at a connection-side terminal end of the first feeder line; the first feed substrate has a first shield spacer disposed therebeneath, and a second shield spacer disposed just thereabove, each of the first shield spacer and the second shield spacer having a hollow portion hollowed out to a size encompassing the first feeder line and the first patch pattern so as to define a corresponding one of the first dielectric and the second dielectric in a respective one of the positions beneath and just above the first feed substrate; the first feed substrate is a polymide film having a thickness of 100 μm or less; each of the first dielectric and the second dielectric has a thickness of 0.3 λg, λg being the effective wavelength at an operating frequency; the second feeder line is provided on the second feed substrate together with a second patch pattern to extend in two directions from the second patch pattern to respective two output ends of the second feeder line; and the second ground conductor has a first slit formed in a portion thereof located approximately intermediate between the first patch pattern and the second patch pattern, and wherein: the first slit is configured such that a longitudinal direction thereof becomes approximately perpendicular to a longitudinal direction of the second patch pattern; and the hollow portion of the first shield spacer, the second patch pattern, the hollow portion of the second shield spacer, the first slit and the second patch pattern have an overlap region, when viewed from the side of the third ground conductor in a layered direction of the first and second triplate lines.
