Abstract:
In an example embodiment, an electronics package includes one or more insulating layers and an electrically conductive transmission line. The electrically conductive transmission line includes a signal trace disposed substantially parallel to the one or more insulating layers. The electrically conductive transmission line further includes one or more signal vias electrically coupled to the signal trace. The one or more signal vias are configured to pass through at least a portion of the one or more insulating layers. The electronics package further includes one or more electrically conductive ground planes substantially parallel to the one or more insulating layers. The ground planes include one or more signal via ground cuts. The one or more signal via ground cuts provide clearance between the one or more signal vias and the one or more ground planes.
Abstract:
A concentric 'conductor within a via' RF interconnect architecture, has an inner via (63) through which at least one RF signal conductor passes. The inner conductive via is coaxially formed within and stably coaxially aligned within an outer conductive via (53), which serves as a coaxial ground plane that completely surrounds the inner conductive via. The outer conductive via passes through dielectric layers (61, 62) of microstrip or stripline structures (71, 72) on opposite sides of a multi printed circuit laminate (30).
Abstract:
Method for connection of conductors (120, 110) which extend parallel to one another in a device (100, 600) in the microwave range. Each conductor comprises a conductive layer (160; 170), a layer (150; 195, 198) of a dielectric material and a groud plane (140; 180, 190). The ground planes of the two conductors are separated in the device by a core (130) made of a dielectric material. The various layers are arranged on one another in the desired order, and a cavity (310) is arranged in the device, extending from that layer (170) in the first conductor which is to be connected to the second conductor, at right angles to the main direction of this layer, up to and including the layer (150) on which the conductive layer of the second conductor is to lie. A component (400) comprising a stripline conductor is arranged in the cavity, the component being arranged so that electrical contact is brought about between the conductor (470) of the component and that layer (170) in the first conductor which is to be connected to the second conductor. Subsequently, the conductive layer (160) of the second conductor and its remaining ground plane and dielectric layer are arranged on the device so that electrical contact is brought about between the conductor (470) of the component and the conductive layer (160) of the second conductor.
Abstract:
The invention concerns a method and a device for connecting two millimetric elements. The method consists in producing in predetermined sites of each of the millimetric elements (13, 16) connecting zones (8) linked to a ground plane potential; then in carrying out the connection by predetermined links (17) between the connection zones (8) and between the conducting lines (6, 15) of the two millimetric elements (13, 16). The device consists in a coplanar line (17). The invention is particularly applicable to millimetric circuits using micro-strip conducting lines.
Abstract:
A wiring board provided with a line (1), a shield pattern (2) formed in parallel with the line (1), a conductor layer (4) formed so as to face the line (1) and the shield pattern (2) through an insulating layer (3), a conductor layer (6) formed so as to face the line (1) and the shield pattern (2) through an insulating layer (5), and conductive pillars (7a, 7b) for connecting the conductor layer (4) to the conductor layer (6). The conductive pillars (7a, 7b) are connected to each other through the shield pattern (2). In the above structure, by supplying the ground potential to the shield pattern (2), conductor layers (4, 6), and conductive pillars (7a, 7b), an electromagnetic field is blocked in the direction where the line (1) extends over 360 DEG about the line (1).
Abstract:
In an exemplary embodiment, an antenna architecture comprises a single aperture having both receive elements and transmit elements, where the single aperture has the performance of a dual-aperture but in about half the size. Moreover, in the case of an array with inclined elements, there is the need to interconnect a planar substrate with an inclined substrate at an angle. An exemplary single aperture comprises a metal core having a thick pass-through slot from a first side to a second side; connecting the inclined substrate to the first side of the metal core, and connecting a second substrate to the second side of the metal core. Furthermore, an RF signal is communicated between the first substrate and the second substrate in a contactless manner through the thick pass-through slot.
