Abstract: An antenna includes: an antenna body; and a plurality of slot antenna units provided on the antenna body and arranged to be a slot antenna array, wherein each of the plurality of slot antenna units includes a cavity formed within the antenna body and a slot penetrating through a surface of the antenna body, and the slot and the cavity have sizes to enable transmission of millimeter waves in 5th generation (5G) mobile communication.

Abstract: An electronic device includes: a housing having an accommodation cavity, a circuit board being arranged in the accommodation cavity; a screen holder coupled to the housing and comprising at least one antenna radiator electrically coupled to the circuit board to receive and/or transmit signals; and a screen with an edge arranged on the screen holder.

Abstract: The antenna module includes: a first radiator having an opening; a second radiator located inside the opening, the second radiator being spaced apart from the first radiator; a first feed point located on the first radiator, the first feed point being configured for transmitting a wireless signal in a first frequency band; and a second feed point located on the second radiator, the second feed point being configured for transmitting a wireless signal in a second frequency band. The second frequency band differs from the first frequency band.

Abstract: An antenna unit, an array antenna and an electronic device are provided. The antenna unit includes a first microstrip antenna, comprising a first radiating layer coupled to a first dielectric layer wherein the first microstrip antenna operates at a first band, a second microstrip antenna, comprising a second radiating layer, a second dielectric layer, and a ground layer, sequentially coupled, wherein the second radiating layer is coupled to a side of the first dielectric layer facing away from the first radiating layer, and wherein the second microstrip antenna operates at a second band that is smaller than the first band, a first feeder line, electrically coupled to the first radiating layer and the second radiating layer, and a second feeder line, electrically coupled to the second radiating layer and the ground layer.
