Abstract: A first device module comprises a first coupling arrangement; the first coupling arrangement comprising a first inductive coil, a first magnetic core positioned within the first inductive coil to form a first electromagnet, and a first control unit electrically connected to the first inductive coil. The first control unit is configured to supply first DC current to the first inductive coil to generate a first magnetic field to attract a second device module comprising a second magnetic element and a second inductive coil by magnetic force, and first AC current to the first inductive coil to inductively transmit a first data or power signal from the first inductive coil to the second inductive coil.

Abstract: A cover of a device acting as an antenna of the device is disclosed. The device comprises a first body and a second body, wherein the first body comprises: a first conductive portion of a first cover of the device configured as an antenna of the device; a second conductive portion of the first cover configured as a ground of the antenna; and a dielectric slot of the first cover; wherein the second body comprises: a first conductive portion of a second cover of the device; a second conductive portion of the second cover; and a dielectric slot in the second cover; wherein a shape of the first and the second conductive portion of the first body and the dielectric slot of the first body aligns with a shape of the first and the second conductive portion of the second body and the dielectric slot of the second body.

Abstract: An apparatus for wireless communication comprising: a conductive member (22) comprising: a first radiator (24) configured to resonate in an operational frequency band; a second radiator (26) configured to resonate in an operational frequency band; a first non-conductive slot (28) between at least the first radiator (24) and the second radiator (26), the first non-conductive slot (28) being oriented in a first direction (parallel to the Y-axis 38); a third radiator (30) configured to resonate in an operational frequency band; and a second non-conductive slot (32) between at least the third radiator (30) and the first radiator (24), the second non-conductive slot (32) being oriented in a second direction (parallel to the X-axis 36), different to the first direction (38).
