Abstract
An electronic device includes a first layer with an antenna and a second metal layer that extends over the entire first layer. The second metal layer includes at least one laterally-closed cavity that is located vertically above the antenna. The cavity is filled, at least in part, by a resin material. A first plate supporting a second metal plate extends over the cavity with the second metal plate positioned vertically above the antenna. The first metal plate may be supported by a ledge within the cavity. Alternatively, the second metal plate is embedded in the resin filling the cavity, with the second metal plate positioned vertically above the antenna.
Claims29
An electronic device, comprising:
- a first layer comprising an antenna;
- a second metal layer extending over the first layer and comprising at least one laterally-closed cavity, said laterally-closed cavity being located vertically above the antenna;
- wherein lateral walls of said laterally-closed cavity include an edge forming a ledge support, wherein said edge delimits the laterally-closed cavity into a first cavity portion and a second cavity portion;
- a resin material filling the first cavity portion of said laterally-closed cavity;
- and
- a cavity closing structure comprising:
- a first plate covering at least part of the laterally-closed cavity, wherein said first plate rests on said edge and is mounted within said second cavity portion;
- and
- a second metal plate supported by the first plate and located vertically above the antenna.
An electronic device, comprising:
- a first layer comprising an antenna;
- a second metal layer extending over the first layer and comprising at least one laterally-closed cavity, said laterally-closed cavity being located vertically above the antenna;
- a resin material filling said laterally-closed cavity;
- and
- a cavity closing structure comprising:
- a first plate covering at least part of the laterally-closed cavity;
- and
- a second metal plate supported by the first plate and located vertically above the antenna;
- wherein said second metal layer includes at least one hole separate from the laterally-closed cavity, and wherein the first plate includes a foot portion that extends into said at least one hole.
An electronic device, comprising:
- a first layer comprising a first antenna;
- a second metal layer extending over the first layer and comprising a first laterally-closed cavity, said first laterally-closed cavity being located vertically above the first antenna;
- a resin material filling said first laterally-closed cavity;
- and
- a first metal plate embedded in the resin material in the first laterally-closed cavity and located vertically above the first antenna;
- wherein lateral walls of said first laterally-closed cavity form an acute angle with respect to an upper surface of the first layer.
An electronic device, comprising:
- a first layer comprising a first antenna;
- a second metal layer extending over the first layer and comprising a first laterally-closed cavity, said first laterally-closed cavity being located vertically above the first antenna;
- a resin material filling said first laterally-closed cavity;
- and
- a first metal plate embedded in the resin material in the first laterally-closed cavity and located vertically above the first antenna;
- wherein lateral walls of said first laterally-closed cavity form an obtuse angle with respect to an upper surface of the first layer.
An electronic device, comprising:
- a first layer comprising a first antenna;
- a second metal layer extending over the first layer and comprising a first laterally-closed cavity, said first laterally-closed cavity being located vertically above the first antenna;
- a resin material filling said first laterally-closed cavity;
- and
- a first metal plate embedded in the resin material in the first laterally-closed cavity and located vertically above the first antenna;
- wherein said first layer further comprises a second antenna, and wherein said second metal layer further comprises a second laterally-closed cavity, said second laterally-closed cavity being located vertically above the second antenna and filled by said resin material, and further comprising a second metal plate embedded in the resin material in the second laterally-closed cavity and located vertically above the second antenna.
