Abstract (en)
[origin: DE19725492C1] The arrangement includes a feeder network (2) and a planar line structure (5) of an antenna which are applied on different sides of a two layered substrate (3,4) with an earth surface (6) between both substrate layers. The square hollow conductor (1) is a hollow conductor elbow which is overlapped with a microstripline (2). A first hollow conductor section (7) is provided in the substrate plane and a second hollow conductor section (8) is provided orthogonally to the substrate plane. The hollow conductor does not have a wall in the substrate plane and the walls which are orthogonal on the substrate are contacted with the earth surface. A bridge (9) is provided in the hollow conductor and has a first section (10) in the first hollow conductor section contacting the microstripline. A second section of the bridge is provided in the second hollow conductor section.
