An antenna structure includes a ferromagnetic patch, first metal conductive lines, second metal conductive lines, and metal connection elements. The ferromagnetic patch has a first surface and a second surface, and the second surface is opposite to the first surface. The first metal conductive lines are disposed on the first surface of the ferromagnetic patch. The second metal conductive lines are disposed on the second surface of the ferromagnetic patch. The metal connection elements penetrate the ferromagnetic patch. The metal connection elements further connect the first metal conductive lines to the second metal conductive lines, respectively.

Antenna structure and mobile device

A loop antenna is provided, which includes a first loop section, a second loop section and a third loop section. The first loop section surrounds and defines an empty area. The second loop section surrounds and connects the first loop section, and an annular groove is formed between the first loop section and the second loop section. The third loop section surrounds and connects the second loop section. The width of a gap between the third loop section and the second loop section is smaller than the width of the annular groove.

Loop antenna

A near field communication (NFC) antenna including a dielectric substrate, a coil, and a coupling structure is provided. The coil is disposed on the dielectric substrate. The coupling structure includes at least one coupling branch. Two ends of the coupling branch are respectively connected to two different connection points on the coil. The coupling structure is configured to improve the isotropic characteristics of the NFC antenna.

Near field communication antenna

A transmission device for a near field communication (NFC) device includes a matching circuit, a connecting interface with a first width for connecting an operating circuit of the NFC device, a first transmission line electrically connected between an antenna of the NFC device and the matching circuit, and a second transmission line electrically connected between connecting interface and the matching circuit, including an increasing width portion and a constant width portion, wherein a width of the second transmission increases from the first width to a second width within the increasing width portion and keeps the second width within the constant width portion, wherein the second width is greater than and related to the first width.

Transmission device and near field communication device using the same

A touch panel control method applied to a touch panel including at least one antenna and a touch sensing structure having a plurality of touch sensing elements is provided. In the touch panel control method, a scan signal is transmitted to at least one of the plurality of touch sensing elements, and a sensing signal sensed by at least one of the plurality of touch sensing elements is received. Whether the at least one antenna starts operating is detected by a control sensor, and if so, operation of a first plurality of touch sensing elements of the plurality of touch sensing elements is stopped, wherein each of the first plurality of touch sensing elements overlaps the at least one antenna.

Touch panel and a control method thereof

A wideband antenna for a wireless communication device includes a grounding element, a radiating element, extending in a first direction, for transmitting and receiving wireless signals, a feed-in terminal electrically connected to the radiating element, for transmitting a feed-in signal to the radiating element, and a first parasitic radiating element, extending in the first direction, having a side separated from a side of the radiating element by a first distance, and another side separated from the grounding element by a second distance. The first distance allows the first parasitic radiating element and the radiating element to generate a coupling effect to form a slot antenna for transmitting and receiving wireless signals, and the second distance allows the first parasitic radiating element and the grounding element to generate a coupling effect to form a coupling path to the grounding element to increase bandwidth.
