摘要： Embodiments of this application disclose an electronic device, including a conductive frame and a first antenna unit. The conductive frame is disposed around a periphery of the electronic device. The first antenna unit includes: a first conductive layer and a second conductive layer, where the first conductive layer and the second conductive layer are spaced apart in a thickness direction of the electronic device; a conductive connection portion, where the conductive connection portion is configured to connect the first conductive layer and the second conductive layer; and a first conductive frame, where the first conductive frame is a part of the conductive frame. A first slot exists between the first conductive layer and the first conductive frame. The conductive connection portion, the first conductive frame, the first conductive layer, and the second conductive layer enclose a first cavity. In this way, an electromagnetic wave may be radiated or received through the first slot between the first conductive layer and the first conductive frame, so that no slot is required on a surface of a metal plate, thereby improving integrality of the metal plate.

摘要： An antenna apparatus includes a feeding antenna inside an electronic device and one or more antenna elements, such as a floating metal antenna, disposed on a rear cover of the electronic device. The floating metal antenna and a feeding antenna inside the electronic device may form a coupling antenna structure. The feeding antenna may be an antenna fastened on an antenna support (which may be referred to as a support antenna). The feeding antenna may alternatively be a slot antenna formed by slitting on a metal middle frame of the electronic device. The antenna apparatus may be implemented in limited design space, thereby effectively saving antenna design space inside the electronic device. The antenna apparatus may generate excitation of a plurality of resonance modes, so that antenna bandwidth and radiation characteristics can be improved.

摘要： Embodiments of this application provide an antenna system and an electronic device. The antenna system includes a first antenna and a second antenna. The first antenna includes a first radiator and a second radiator, and the second antenna includes the first radiator and a third radiator. Two ends of the first radiator are electrically connected to a ground separately, a first end of the second radiator is relatively far away from a first end of the third radiator, and the first end of the second radiator and the first end of the third radiator are separately connected to or coupled to the first radiator. A second end of the second radiator is disposed opposite to a second end of the third radiator, to form a gap. The antenna system feeds the first antenna through a first feeding connection point on the second radiator, and feeds the second antenna through a second feeding connection point on the third radiator. In this way, a new antenna system is constructed. In the system, high isolation between the first antenna and the second antenna can be implemented, and miniaturization of an antenna diameter and a low SAR value can be further implemented.

The second feed is electrically connected to the second feedpoints through an adjustment circuit. The second feedpoints are configured to feed a radio frequency signal into the radiator, and the second feedpoints excite, by using the adjustment circuit, the radiator to generate a TM 10 mode, so that the radiator has performance of a dual-microstrip antenna. The microstrip antenna provided in this application resolves a technical problem of a high SAR value of an existing microstrip antenna.

摘要： An antenna design solution is provided. A metal frame and a PCB ground layer of an electronic device are used to form a slot. Through symmetric feeding and anti-symmetric feeding, the slot can be excited to generate two slot antenna patterns: a CM slot antenna pattern and a DM slot antenna pattern, so that characteristics such as high isolation and a low ECC of a MIMO antenna can be achieved in a wideband. In addition, the two slot antenna patterns share a same slot antenna radiator, so that antenna design space can be saved.
