摘要： An antenna structure includes a ground element, a feeding radiation element, a first radiation element, a second radiation element, a third radiation element, and a switch circuit. The ground element provides a ground voltage. The feeding radiation element has a feeding point. The feeding radiation element is coupled through the first radiation element to the second radiation element. The third radiation element is coupled to the feeding radiation element. The feeding radiation element is disposed between the first radiation element and the third radiation element. The switch circuit selectively couples the second radiation element to the ground voltage according to a control voltage. A slot is formed and surrounded by the ground element, the feeding radiation element, the first radiation element, and the second radiation element.

摘要： Introduced here is an ingestible device comprising a capsule having a central axis therethrough, at least one propulsion component, and at least one motor configured to supply motive power to the propulsion component(s). The propulsion component(s) may be disposed at locations radially offset from the central axis. Upon receiving input indicative of a request to alter a position and/or an orientation of the ingestible device, the motor(s) can supply motive power to some or all of the propulsion component(s) to cause movement of the ingestible device.

摘要： An RFID tag is provided as a wireless communication device that transmits and receives a communication signal. The RFID tag includes a base material, a conductor pattern including an antenna pattern provided at the base material, and a discharge auxiliary electrode. The discharge auxiliary electrode is disposed at a position where the discharge auxiliary electrode overlaps or is close to the antenna pattern in planar view, and lowers a dielectric breakdown voltage between two different opposed portions on the conductor pattern. With this configuration, ignition and combustion is prevented even in a situation in which the RFID tag is subjected to high-frequency power for heating a food item while attached to the food item.

摘要： A tunable antenna includes a base supporting a support and hollow tube opposing and spaced apart from one another, and spaced-apart and parallel plates. Each plate is coupled only at one end thereof to one of the support and hollow tube. One of the plates located furthest from the base extends past the hollow tube and is spaced apart therefrom. A shaft extends through the hollow tube and the one plate extending past the hollow tube. A tuning plate is coupled to the end of the shaft. A tuning piston is coupled to the shaft and is adapted for movement within the hollow tube where such movement changes the resonant frequency of the antenna.

摘要： Various methods, apparatus, devices and systems are provided for electrically short antennas for efficient broadband transmission. In one example, among others, a system includes a segmentally time-variant antenna and a segment controller that can control conductivity of individual segments of the segmentally time-variant antenna. The conductivity of the individual segments is modulated to allow a pulse to propagate from the proximal end to the distal end of the segmentally time-variant antenna and impede a reflection of the pulse from propagating back to the proximal end of the segmentally time-variant antenna. In another embodiment, a method includes injecting a pulse at a first end of a segmentally time-variant antenna and modulating conductivity of individual segments to allow the pulse to propagate to a second end of the segmentally time-variant antenna and impede a reflection of the pulse from propagating back to the first end.

摘要： 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.
