摘要： Embodiments of this application disclose a terminal monopole antenna, relating to the technical field of antennas. The antenna includes a radiation branch, the radiation branch includes at least one radiator, and a first end of the radiator is electrically connected to a reference ground through a first inductor. When the terminal monopole antenna is directly fed by a feeding point, a second end of the radiator is electrically connected to the feeding point. When the terminal monopole antenna is coupled and fed, the second end is electrically connected to the reference ground through a second inductor. The terminal monopole antenna further includes a feeding branch, the feeding branch is configured to perform coupled feeding to the radiation branch. A length of the radiation branch is less than a quarter of an operating wavelength of the terminal monopole antenna.

摘要： An antenna apparatus includes a first side metal frame having a first slot and a first feed point, and a bottom metal frame having a second slot and a second feed point. A first ground point is arranged between the bottom metal frame and a second side metal frame of the electronic device. The apparatus also includes a plurality of tuning switches including a first tuning switch connected to the first side metal frame, and a second tuning switch and a third tuning switch connected to the bottom metal frame. The second tuning switch is connected to a first side of the second slot, the third tuning switch is connected to a second side of the second slot, and the first side is closer to the first side metal frame than the second side. A feeder selectively connects to the first feed point or the second feed point.

摘要： This application provides an antenna assembly. The antenna assembly includes at least a first antenna and a second antenna. The first antenna includes a first feed point and a first radiator connected thereto. The second antenna includes a second feed point and a second radiator connected thereto. There is a gap between the first radiator and the second radiator. An end of the second radiator close to the gap is provided with a first ground wire shared by the first antenna and the second antenna. An end of the second radiator away from the gap is provided with a second ground wire. Because currents excited by the first antenna and the second antenna are orthogonally complementary, crosstalk does not occur between the ground currents of the first antenna and the second antenna.

摘要： A high-isolation terminal antenna system, to provide improved radiation performance and isolation by combining current loop antennas and/or magnetic loop antennas with different position features. The terminal antenna system includes a first antenna and a second antenna, and the first antenna and the second antenna include at least one current loop antenna or magnetic loop antenna. When the current loop antenna operates, a uniform magnetic field is distributed between a radiating element of the current loop antenna and a reference ground. When the magnetic loop antenna operates, a uniform electric field is distributed between a radiating element of the magnetic loop antenna and the reference ground. The first antenna and the second antenna are arranged at a same edge of an electronic device, or are arranged at two opposite edges of the electronic device.

摘要： An antenna apparatus is provided. The antenna apparatus is formed by using a metal frame of an electronic device. Slots are arranged on both a bottom metal frame and a side metal frame to balance free space radiation efficiency and handheld radiation efficiency. In a free space scene, a portrait mode of an antenna is strong, and free space radiation efficiency is good. When an electronic device is held in the hand, a lateral mode of the antenna is strong, and handheld radiation efficiency is good.
