A method of manufacturing a stamped antenna includes providing a sheet of metallic material for a first stamping. A first stamping of the sheet of metallic material is performed to form at least one antenna that includes traces, contacts, a carrier connected to the traces, and at least one tie-bar connected between the traces. A pad is provided with at least one pressure sensitive adhesive area that is provided on the pad in substantially the same shape as the traces of the antenna. The pressure sensitive adhesive area is aligned with the traces of the antenna, and then bonded to the traces of the at least one antenna. A second stamping of the at least one antenna and the pressure sensitive adhesive is then performed to remove the at least one carrier and the at least one tie-bar connected to the traces.

A multi-layer Printed Circuit Board PCB and a wireless communication node are disclosed in the present invention. The multi-layer PCB which is to be assembled in the communication node may include multiple radio layers (501) on one side of the PCB and at least one antenna layer (502) on another side of the PCB. At least one radio component is to be mounted on a surface layer of the multiple radio layers and at least one antenna element is to be patched on a surface layer of the at least one antenna layer. In such way, legacy connectors from the filter unit respectively to the antenna unit and the radio unit in conventional PCB can be left out to decrease the size of the PCB.

A system and method for tracking medical articles located in a container includes a hybrid isolated magnetic dipole (IMD) probe that provides an activating EM energy RF field having a magnetic near field at least as great as the electric near field, both of which cover the entire interior of the container. The probe comprises a main element having capacitive coupling across at least one slot and spacing above a ground plane to thereby form an isolated electric field and an equally strong or stronger magnetic field that fills the interior of the container to activate RFID tags therein. A dual system is provided for larger containers. A dynamic impedance tuning system controls the probe impedance for increased efficiency in transferring power to the interior of the container. Beam steering is provided with the IMD probe.

A broadband multi-bay antenna array comprising an upper antenna element group and a lower antenna element group. Each of the upper antenna group and lower antenna group comprises a pair of antenna elements separated by a distance of one-half wavelength at mid-band wavelength. Radiating elements of the first antenna in each pair are positioned in a first orientation and radiating elements of the second antenna in each pair are positioned in a second orientation which differs from the orientation of the first antenna by 180 degrees (flipped over). A center feed input port is positioned between the upper antenna element group and the lower antenna element group and is electrically coupled to each of the first, second, third and fourth antenna elements.

An electronic device has wireless communications circuitry including an adjustable antenna system coupled to a radio-frequency transceiver. The adjustable antenna system may include one or more adjustable electrical components that are controlled by storage and processing circuitry in the electronic device. The adjustable electrical components may include switches and components that can be adjusted between numerous different states. The adjustable electrical components may be coupled between antenna system components such as transmission line elements, matching network elements, antenna elements and antenna feeds. By adjusting the adjustable electrical components, the storage and processing circuitry can tune the adjustable antenna system to ensure that the adjustable antenna system covers communications bands of interest.

Introduced here is an ingestible device that can comprise a capsule, an intervention tool, and a processor configured to controllably employ the intervention tool to manipulate structures in a living body. The ingestible device may further comprise a camera that is configured to generate images of various in vivo environments as the ingestible device traverses the living body. These images may be wirelessly transmitted to an electronic device located outside of the living body to enable greater control over the intervention tool.
