Configurable faraday shield
View Patent ↗A configurable Faraday shield is provided. The configurable Faraday shield includes a plurality of ribs. Each of the ribs can be spaced apart from one another along a circumferential direction. Furthermore, at least a portion of the configurable Faraday shield is movable between at least a first position and a second position to selectively couple the configurable Faraday shield to a radio frequency ground plane. When the at least a portion of the configurable Faraday shield is in the first position, the configurable Faraday shield can be decoupled from the radio frequency ground plane such that the configurable Faraday shield is electrically floating. Conversely, when the at least a portion of the configurable Faraday shield is in the second position, the configurable Faraday shield can be coupled to the radio frequency ground plane such that the configurable Faraday shield is electrically grounded.
1. A configurable Faraday shield defining an axial direction, a circumferential direction, and a radial direction, the configurable Faraday shield comprising:
a plurality of ribs, each of the ribs spaced apart from one another along the circumferential direction, the plurality of ribs coupled between a first radio frequency ground plane and a second radio frequency ground plane;
a plurality of conductive straps; and
a locking member movable between at least a first position and a second position to selectively couple each of the plurality of ribs to the first radio frequency ground plane via a corresponding conductive strap of the plurality of conductive straps; wherein the locking member comprises a ring defining a plurality of notches.
2. The configurable Faraday shield of claim 1 , wherein each of the plurality of conductive straps is coupled to a corresponding rib of the plurality of ribs.
3. The configurable Faraday shield of claim 1 , wherein the locking member rotates about the axial direction and translates along the axial direction to move between the first position and the second position.
4. The configurable Faraday shield of claim 1 , wherein each of the plurality of conductive straps comprise:
a first portion coupled to a corresponding rib of the plurality of ribs;
a second portion that is bent relative to the first portion, and
a third portion that is bent relative to the second portion, the third portion being substantially parallel to the first portion.
5. The configurable Faraday shield of claim 4 , wherein the second portion is bent relative to the first portion at an angle that is greater 90 degrees.
6. The configurable Faraday shield of claim 4 , wherein at least one of the plurality of conductive straps comprises beryllium copper.
7. The configurable Faraday shield of claim 4 , further comprising:
a dielectric spacer positioned between the first radio frequency ground plane and the plurality of ribs along the axial direction.
8. The configurable Faraday shield of claim 7 , wherein:
when the locking member is in the first position, each of the plurality of conductive straps is positioned within a corresponding notch of a plurality of notches defined by the locking member such that the plurality of conductive straps are spaced apart from the first radio frequency ground plane; and
when the locking member is in the second position, the locking member presses the third portion of each of the plurality of conductive straps against the first radio frequency ground plane.
9. The configurable Faraday shield of claim 7 , wherein the locking member is in an intermediate third position, the locking member presses the second portion of each of the plurality of conductive straps against the dielectric spacer.
