An antenna includes a self-supporting electrically conductive wire having a width (W) and extending longitudinally along a length and between first and second ends of the conductive wire. The conductive wire forms one or more loops and comprises an electrically conductive layer disposed on and aligned with an adhesive layer. A width and a length of each of the conductive and adhesive layers are substantially co-extensive with the width and the length of the conductive wire.

Self-supporting antenna

The present disclosure relates to a magnetic shielding tape, which is capable of shielding a high-to-low frequency of a signal transmitted through a cable in shielding of a magnetic field which flows in such a cable or is emitted therefrom, and a method for manufacturing the same. The basic magnetic shielding tape comprises: &#x2014;a thin film magnetic layer including at least one metal ribbon sheet which is divided into a plurality of fine pieces by flaking process, and a gap provided between adjacent fine pieces among the plurality of fine pieces; &#x2014;a cover film layer adhered to one side surface of the thin film magnetic layer through a first adhesive layer; and&#x2014;a conductive layer adhered to the other side surface of the thin film magnetic layer through a second adhesive layer, wherein a size of the gap is determined according to a frequency band of the signal.

In some examples, a sensor comprises a circuit including an inductor. The inductor comprises an inductor layer, a reference layer comprising at least one of an electrically conductive material or a magnetic material, and a variable layer formed between the reference layer and inductor layer. A thickness of the variable layer may be configured to change upon application of a force external to the variable layer thereby causing a change in position of the reference layer relative the inductor layer, and the change in position of the reference layer relative the inductor layer changes an inductance of the inductor. The sensor may be configured to detect the force based on the change in inductance of the inductor.

Force responsive inductors for force sensors

Provided is an electronic circuit board assembly. The electronic circuit board assembly includes an electronic circuit board, a plurality of electronic circuit devices disposed on the electronic circuit board, an electromagnetic interference (EMI) shielding structure configured to shield an electromagnetic wave generated from the plurality of electronic circuit devices, and a thermal pad configured to dissipate heat generated from the plurality of electronic circuit devices. The EMI shielding structure covers the plurality of electronic circuit devices and is attached to the electronic circuit board, and the thermal pad is disposed between the plurality of electronic circuit devices and the EMI shielding structure, contacts the plurality of electronic circuit devices and the EMI shielding structure, and thereby can transfers the heat generated from the plurality of electronic circuit devices to the EMI shielding structure.
