Claims17
An electromagnetic interference shield, comprising conductive material having a plurality of elongated openings therein, each opening being non-uniform in a dimension perpendicular to a longitudinal axis of the opening.
An electromagnetic interference shield, comprising conductive material having a plurality of elongated openings therein, each opening having a non-uniform three dimensional shape.
An electromagnetic interference shield, comprising conductive material having a plurality of elongated openings therein, each opening including a first portion having a non-uniform three dimensional first shape and a second portion having a second shape different from the first shape.
An electromagnetic interference shield, comprising conductive material having a plurality of openings therein, each opening including an entry and an elongated conduit connected to and extending away from the entry, the entry having a first cross sectional area and the conduit having a second cross sectional area substantially smaller than the first cross sectional area.
An electromagnetic interference shield, comprising conductive material having a plurality of openings, each opening characterized by a receiving antenna and a waveguide operatively connected to the receiving antenna.
An electromagnetic interference shielded electronic module, comprising:
- an electronic device capable of generating electromagnetic radiation;
- and
- a housing at least partially enclosing the electronic device, the housing having a plurality of walls at least one of which comprises a conductive material having a plurality of openings therein, each opening having a non-uniform three dimensional shape.
