Abstract: An electronic device includes a first antenna unit. The first antenna unit includes a first radiator, the first radiator is configured to receive and transmit a radio frequency signal, and the first radiator is further configured to sense capacitance or a capacitance change between the first radiator and a detected object when the detected object approaches. The electronic device further includes a sensor chip. The sensor chip is configured to obtain the capacitance or the capacitance change, to determine a proximity of the detected object relative to the first radiator, and the sensor chip is electrically connected to a minimum-voltage point on the first radiator by a conducting wire.

Abstract: An antenna having high isolation and a low cross-polarization level, a base station, and a terminal are provided. The antenna includes a radiation layer, a feed layer, and an aperture coupling layer disposed between the radiation layer and the feed layer. The aperture coupling layer includes a metal sheet. A first feeding slot, a second feeding slot, and a middle slot are configured in the metal sheet. The middle slot is located between the first feeding slot and the second feeding slot, and is located in a weak electric field region of the metal sheet. The middle slot is configured between the first feeding slot and the second feeding slot of the metal sheet.

Abstract: A display stack with millimeter-wave antenna functionality comprising a plurality of adj oining layers, the layers comprising at least a cover layer, a touch sensor panel layer comprising a touch sensor arrangement, and a display panel layer. The touch sensor panel layer comprises a first sensor line grid pattern and a second sensor line grid pattern, the first sensor line grid pattern comprising a plurality of continuous first sensor lines, the second sensor line grid pattern comprising a plurality of continuous second sensor lines. At least a part of the first sensor lines and the second sensor lines are configured to function as radiators for the millimeter wave antenna functionality. This allows providing the millimeter wave antenna in the touch sensor panel structure without the antenna and the touch sensor panel interfering with each other.
