Embodiment Construction

[0052] exist figure 1 and 2 In the embodiment of the mechanical and electrical connection device according to the invention shown schematically above, a coaxial cable 1 comprises a central inner conductor 2 made of metal, an outer conductor 3 receiving an alternating current (often implemented as metal or metal-plated braid) and a layer 4 of dielectric material between the two conductors 2,3. The cable 1 is connected to a multilayer stripline 5 comprising a conductive track 6 sandwiched between two conductive surfaces 7 . The ground metal or metal-plated conductive surface 7 forms the ground plane of the multilayer line 5 . A dielectric layer 8, which in this case consists of air and provides electrical isolation, separates the conductive tracks 6 from the conductor surfaces 7 located on either side. The inner conductor 2 of the coaxial cable 1 is electrically connected to the conductive track 6 of the multilayer line 5, for example by means of welding. The mechanical and el...

Abstract

The invention relates to a device for the mechanical and electrical connection between a multilayer line comprising at least one conducting track and at least one ground plane and a coaxial cable comprising an inner conductor and an outer conductor transmitting high-frequency signals, the mechanical and the electrical connection apparatus comprising: means for electrically connecting a coaxial cable to a ground plane of a multilayer line, comprising a conductive surface disposed opposite the ground plane of the multilayer line, wherein a layer of dielectric material isolates the ground plane from the conductive surface so as to A capacitive electrical link is established between the conductive surface and the ground plane; and a mechanical securing means comprising at least one raised pattern made of a dielectric material insertable into a suitable opening formed in the ground plane.

Description

technical field [0001] The present invention relates to a device for mechanical and electrical connection between a coaxial cable carrying high frequency signals and a line comprising multilayer microstrip or stripline. This mechanical and electrical connection device may eg be part of a radio frequency module installed in the base station equipment room. Background technique [0002] In the case of a microstrip type configuration, a grounded conductive surface commonly referred to as a "ground plane" is arranged on one side of a planar dielectric substrate. Conductive tracks are secured to the other side of the dielectric substrate. Microstrip lines usually take the form of printed circuits deposited on one side of a dielectric substrate whose opposite metallized ground plane forms the ground plane. [0003] In a stripline configuration, two continuous ground conductor plates are arranged in parallel on either side of the conductive track. A dielectric layer insulates ea...
