摘要： The present invention provides a terminal antenna and a terminal. The terminal antenna includes a mainboard, a feedpoint disposed on the mainboard, a metal housing, an adjustable apparatus, and at least two adjustable ground points. The mainboard is located on an inner side of the metal housing, the metal housing is electrically connected to the mainboard, and a slot is disposed in the metal housing. The feedpoint and the at least two adjustable ground points each are disposed on a part of the mainboard facing the slot. The at least two adjustable ground points each are electrically connected to the mainboard by using the adjustable apparatus, and the adjustable apparatus is configured to control whether each adjustable ground point is grounded. In embodiments of the present invention, the adjustable apparatus controls whether each adjustable ground point is grounded, so that signals with a same frequency can be radiated from a first end and a second end of the slot of the terminal antenna. This avoids a prior-art problem of low efficiency of a terminal antenna caused because a low-frequency signal or a high-frequency signal radiated by the terminal antenna is rapidly attenuated when a slot in a metal housing is covered by a hand.

摘要： This application provides an antenna and an electronic device that includes the antenna. The antenna includes an antenna body and a feed point and a grounding point that are located on the antenna body. The antenna body includes a first section and a second section that intersect with each other. An electrical length between the feed point and a first end of the antenna body is greater than an electrical length between the feed point and a second end opposite to the first end. The antenna body generates resonance of a second wavelength in a quarter wavelength mode between the feed point and the first end, and the antenna body generates resonance of the second wavelength in a half wavelength mode between the first end and the second end. In this application, mode excitation generated based on the resonance of the second wavelength in the quarter wavelength mode can be enhanced by using the resonance of the second wavelength in the half wavelength mode, so that horizontal mode excitation and vertical mode excitation of the antenna are relatively balanced. Therefore, the antenna can have relatively good radiation performance regardless of whether the electronic device is in free space (FS) or in a handheld state.

摘要： 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. In this way, good antenna performance can be ensured, so that the electronic device can fully use the antenna unit in limited space to implement various scenarios, to improve utilization of antenna space.

摘要： An antenna of a mobile terminal and a mobile terminal are provided. At least two slots are disposed in a metal bezel of the mobile terminal, and the two slots divide the metal bezel into a first metal section, a second metal section, and a third metal section. A radiating element of the antenna includes the second metal section located between the two slots, a first conductor, and a second conductor. The first conductor and the second conductor are separately connected to the second metal section. A feed point is connected to the first conductor by using a matching network. A ground point is connected to the second conductor to form a loop antenna. An electrical length path of a current from the feed point to the second metal section is not equal to an electrical length path of a current from the ground point to the second metal section. In the foregoing technical solutions, the feed point and the ground point are disposed on one side of a central line of the metal section, and the radiating element forms a loop antenna in a circular structure. Therefore, a maximum electric field point is changed and far away from the slot of the metal bezel, thereby reducing impact of a hand on an electric field in a modal, and improving performance of the antenna.
