Patent number: 9265151Abstract: A printed-circuit board arrangement electrically connects the at least one transmitter and/or receiver unit with at least one antenna element, whereas the at least one transmitter and/or receiver unit and the at least one antenna element are at least partially integrated into the printed-circuit board arrangement. In this context, the printed-circuit board arrangement includes different printed circuit boards, which are mechanically connected to one another in a rigid manner. A first part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a first material which is suitable for high-frequency, and a second part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a second material different from the first material, which is still sufficiently suitable for a low frequency and/or for a direct-voltage range.Type: GrantFiled: February 2, 2012Date of Patent: February 16, 2016Assignee: ROHDE & SCHWARZ GMBH & CO.

Patent number: 8779871Abstract: A coupler comprises a first line and a second line in each case with two connectors. The lines run in spatial proximity and are coupled. A first connector of the first line and a first connector of the second line are disposed in spatial proximity. A second connector of the first line and a second connector of the second line are disposed in spatial proximity. A signal does not couple or couples only with a high attenuation from the first connector of the first line to the first connector of the second line. The signal is split, in particular, at the design frequency, into largely identical parts to the second connector of the first line and the second connector of the second line. The first line and the second line in this context are strip conductors.Type: GrantFiled: May 14, 2010Date of Patent: July 15, 2014Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 7859361Abstract: In a directional coupler with two coupled lines arranged in a flat chamber of an enclosed metal housing within the coupling region side-by-side in the longitudinal direction and at a spacing distance from one another, of which the ends are connected to connecting ports attached at the sides of the metal housing, these coupled lines include flat, sheet-metal strip conductors, which are arranged within the coupling region with their broad sides facing towards one another side-by-side at a spacing distance and held by several support elements made of insulating material in a cantilever manner at a spacing distance from the opposing internal walls of the flat metal-housing chamber within the latter. In this context, at least one strip conductor is curved relative to the opposing strip conductor in such a manner that the spacing distance of the strip conductors in coupling region increases starting from the beginning of the coupling region approximately exponentially up to the end of the coupling region.Type: GrantFiled: August 6, 2007Date of Patent: December 28, 2010Assignee: Rohde & Schwarz GmbH & Co.
