Abstract: An antenna apparatus includes a grounding plate, a monopole, a first feeding component, and a second feeding component. A slot on the grounding plate includes a first slot and a second slot that interpenetrate each other, the second slot extends from the first slot to an edge of the grounding plate. The monopole includes a first stub and a second stub extending from the first stub to the second slot, the second stub and the second slot form a feeding structure. The first feeding component is electrically coupled to the grounding plate to feed the feeding structure to excite a first radiation mode of the antenna apparatus. The second feeding component is electrically coupled to the second stub to feed the feeding structure to excite a second radiation mode of the antenna apparatus. Polarizations in the two radiation modes are orthogonal.

Abstract: A single feed antenna design is conducted on a radiator of a specific shape (for example, a strip radiator or a slot radiator) to excite a plurality of antenna modes. For example, performing a feed design on a strip radiator may excite a CM wire antenna mode and a DM wire antenna mode. For another example, performing a feed design on a slot radiator may feed a CM slot antenna mode and a DM slot antenna mode. The antenna design may be used to cover a plurality of frequency bands when an antenna is miniaturized.

Abstract: An antenna structure includes a first antenna element connected to a first port, and a second antenna element connected to a second port. The antenna structure is operable to simultaneously transceive: a first signal via electric or magnetic current flow through the first antenna element in a symmetrically excited mode in which current flows symmetrically through the first antenna element and/or an asymmetrically excited mode in which current flows asymmetrically through the first antenna element, the first antenna element resonates at a first resonant frequency; and a second signal via electric or magnetic current flow through the second antenna element in a symmetrically excited mode in which current flows symmetrically through the second antenna element and/or an asymmetrically excited mode in which current flows asymmetrically through the second antenna element, the second antenna element resonates at a second resonant frequency.

Abstract: A terminal comprises a printed circuit board (PCB), a PCB floor, and a rear cover. The metal frame is disposed at edges of the PCB floor. The PCB floor is disposed between the PCB and the rear cover, and the PCB floor is used to ground electronic components. The antenna apparatus may include a split antenna formed by a split provided on the metal frame, and a slot antenna formed by a slot connecting to the split. The slot may be connected to the split at a middle position on one side of the slot, and the slot may be provided on the metal frame of the terminal or on a PCB floor of the terminal.

Abstract: This application discloses a storage system, a storage device, and a hard disk drive scheduling method. The storage system includes M disk groups, a power supply system, and a controller, and M is a natural number not less than 3. Each of the M disk groups includes at least one hard disk drive. The controller is configured to control a hard disk drive in a first disk group of the M disk groups to be in an active state to process a first group of service requests, and control a hard disk drive in a second disk group of the M disk groups to switch from the inactive state to a spin up state when the hard disk drive in the first disk group is in the active state.
