Abstract: 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.

Abstract: This application provides an antenna unit and an electronic device. A signal at a C-mode port and a signal at a D-mode port of a same loop antenna in any antenna unit are respectively excited by using two feeds, and the antenna unit is electrically symmetrically disposed, so that the signal at the C-mode port is self-cancelled at the D-mode port, and the signal at the D-mode port is self-cancelled at the C-mode port, to implement signal isolation between the two ports and interference self-cancel, and the signal at the C-mode port and the signal at the D-mode port can be complementary to each other in different radiation directions, to implement two antennas with high isolation and a low envelope correlation coefficient ECC based on the same loop antenna.

Abstract: 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. In addition, the two slot antenna patterns share a same slot antenna radiator.
