Abstract
A space-borne antenna system includes a number of panels being moveable to each other and having a gap in between them when the panels are arranged in an operation condition. The system also includes an RF distribution network for providing transmit signals to the number of panels and combining received signals from the number of panels. The system further includes a set of choke flange assemblies that allow a contactless inter-panel signal transmission across a dedicated gap. A respective choke flange assembly is arranged on the far side of a radiating surface of the dedicated adjacent panels. The system also includes an RF seal assembly for suppressing a signal coupling of signals radiated from the number of panels to the set of choke flange assemblies by sealing the gap.
Claims13
A space-borne antenna system, comprising:
- a number of panels in an operational position in which there is a gap between the number of panels;
- a choke flange assembly configured to transmit inter-panel signals across the gap;
- and
- an RF seal assembly configured to suppress a signal coupling of signals radiated from the number of panels to the choke flange assembly by sealing the gap;
- wherein the RF seal assembly is arranged at a hinge line and comprises a first seal profile and a second seal profile that are affixed as an opposing pair in the gap between the number of panels;
- wherein the first seal profile and the second seal profile each comprise a first portion which is attached to a respective panel.
A space-borne antenna system, comprising:
- a number of panels configured to move by means of a hinge between a first position and a second position, wherein the second position is an operational position in which there is a gap between the number of panels;
- a choke flange assembly configured to transmit inter-panel signals across the gap;
- and
- an RF seal assembly configured to suppress a signal coupling of signals radiated from the number of panels to the choke flange assembly,
- wherein the RF seal assembly is arranged at a hinge line of the hinge.
A space-borne antenna system, comprising:
- a number of panels in an operational position in which there is a gap between the number of panels;
- a choke flange assembly configured to transmit inter-panel signals across the gap;
- and
- an RF seal assembly configured to suppress a signal coupling of signals radiated from the number of panels to the choke flange assembly by sealing the gap,
- wherein the RF seal assembly comprises a first seal profile and a second seal profile that are affixed as an opposing pair in the gap between the number of panels,
- wherein the first seal profile and the second seal profile each comprise a first portion which is attached to a respective panel, and
- wherein the first and the second seal profiles are L-shaped, in a side view in a longitudinal section through the antenna system.
