摘要： This application relates to an antenna and a mobile terminal, where the antenna includes a conductive support and a feeding part. The conductive support includes a first portion, a second portion, a third portion, and a fourth portion that are all made of conductive materials and that jointly enclose a cavity. The first portion and the third portion are disposed opposite to each other and are respectively connected to a head end and a tail end of the second portion, and the fourth portion and the second portion are disposed opposite to each other. The second portion is disposed on an inner side of a display of the mobile terminal, the third portion is a part of a side frame of the mobile terminal, and the fourth portion is located on an outer side or an inner side of a back cover of the mobile terminal, or is a part of the back cover. The conductive support is provided with a gap, the gap is disposed between the fourth portion and the first portion, or is disposed in the fourth portion. The feeding part is configured to feed an electromagnetic wave signal, and excite the conductive support to generate a current, and the antenna can radiate an electromagnetic wave signal by the configuration of the cavity and the gap. The antenna provided in this application has a low requirement on a clearance environment, and can meet an antenna radiation function.

摘要： This application provides an antenna apparatus and a terminal device. The antenna apparatus includes a first medium- and high-band antenna, the terminal device includes a metal middle frame and a metal frame, a slot is opened on a side of the metal middle frame, and the first high-band antenna includes a first feed point (101), a first dipole antenna (102), and a radiating slot (103), where the radiating slot (103) is constituted by the metal middle frame and the metal frame, a first end of the radiating slot (103) is connected to the side slot of the metal middle frame and is grounded by using the metal middle frame, and an opening of a second end of the radiating slot is disposed at a bottom edge of the metal frame; where the first dipole antenna (102) is connected to the first feed point (101); and the first dipole antenna (102) is spaced from the radiating slot (103), and the first dipole antenna is orthogonal to the radiating slot. The antenna apparatus in the embodiments of this application helps reduce a requirement of an antenna for clearance.
