Abstract: A mobile terminal and a mobile terminal antenna production method. The mobile terminal uses an insulation film layer on an insulation rear housing as a carrier of a radiating element of an antenna, and the radiating element is located within the entire mobile terminal. A feed and an electric-conductor are disposed on a circuit board, and the electric-conductor is electrically connected to the feed. There is a gap between the radiating element and the electric-conductor, and the electric-conductor indirectly couples the radiating element in a capacitively coupled manner.

Abstract: An example antenna system includes a first antenna including a strip-shaped antenna radiator. The antenna radiator has a first end and a second end. At least one of a first radiator section in which the first end is located or a second radiator section in which the second end is located is used as a radiator of a second antenna. One of two first filters is connected between the first antenna radio frequency source and an antenna feed point, and the other first filter is connected between a ground and an antenna ground point. One of two second filters is connected between the second antenna radio frequency source and at least one of the first radiator section or the second radiator section, and the other second filter is connected between the ground and at least one of the first radiator section or the second radiator section.

Abstract: A terminal is disclosed, wherein a metal back cover of the terminal includes a slot. The slot divides the metal back cover into two parts. One of the two parts is used as an antenna radiator. The antenna radiator includes a signal feed point, a first ground point, and at least one second ground point, so that an antenna of the terminal has four resonance points. The signal feed point is connected to a matching network, the first ground point is grounded by a switch device, and the second ground point is grounded. A distance between the signal feed point and the first ground point is less than a distance between the signal feed point and the second ground point, and none of the signal feed point, the first ground point, and the second ground point is located in an end of the slot.

Abstract: A mobile terminal and a mobile terminal antenna production method. The mobile terminal uses an insulation film layer on an insulation rear housing as a carrier of a radiating element of an antenna, and the radiating element is located within the entire mobile terminal, thereby effectively increasing a height of the radiating element of the antenna relative to a circuit board with the antenna not affecting an appearance of the mobile terminal. Compared with a conventional support solution, this manner can increase a height of about 0.2 mm to 0.6 mm This reduces an impact caused by a metal component on the circuit board on antenna radiation, and further increases a bandwidth and efficiency of the antenna so that the antenna can cover a frequency band used in a handheld communications system.

Abstract: An antenna 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 three metal sections. A radiating element of the antenna includes a 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.
