Abstract
Coupling arrangement ( ) for a stripline network, which comprises a first ( ) and a second ( ) ground plane, which ground planes are arranged essentially parallel to one another, extend in a common main direction, and each have at least one aperture ( ), a stripline conductor ( ) arranged between the first ( ) and the second ( ) ground plane, a first dielectric layer ( ) located between the stripline conductor ( ) and the first ground plane ( ), and a second dielectric layer ( ) located between the stripline conductor ( ) and the second ground plane ( ). The stripline conductor has a first main surface ( ) facing towards the first ground plane and a second main surface ( ) facing towards the second ground plane. In connection with the apertures ( ) of the ground planes, the distance (d , d ′) from the aperture to the most closely located main surface ( ) of the stripline conductor ( ) is considerably exceeded by the distance (d , d ′) from said main surface to the other ground plane ( ). The distances (d , d ′) from the apertures ) of each respective ground plane ( ) to the most closely located main surface ( ) of the stripline conductor ( ) are preferably essentially equal.
