Abstract:
Electrical transmission line arrangement comprisingfirst strip-line conductor which has a main extension in a first direction in a first plane in the transmission arrangement and comprises a first straight line conductor contained in the first plane, a first upper ground plane which is situated at an upper distance from the first conductor and a first lower ground plane which is situated at a lower distance from the first conductor, and a second strip-line conductor which has a main extension in a second direction in a second plane in the transmission line arrangement and comprises a second conductor having a first portion contained in the second plane and second portions contained in a third plane parallel to the second plane, a second upper ground plane which is situated at an upper distance from the second conductor portions and a second lower ground plane which is situated at a lower distance from the second conductor portion, where the respective ground planes are separated from corresponding conductors and from one another by a dielectric material, wherein the first lower ground plane of the first strip-line conductor coincides with the second upper plane of the second strip-line conductor, the main direction of extension of the first strip-line conductor crosses the main direction of extension of the second strip-line conductor, and wherein the second strip-line conductor includes electrical connections that connect the first and second portions of the conductor of the second strip-line conductor, the second upper ground plane, and the second lower ground plane.
