摘要： Embodiments of this application provide an antenna system and an electronic device. The antenna system includes a first antenna and a second antenna. The first antenna includes a first radiator and a second radiator, and the second antenna includes the first radiator and a third radiator. Two ends of the first radiator are electrically connected to a ground separately, a first end of the second radiator is relatively far away from a first end of the third radiator, and the first end of the second radiator and the first end of the third radiator are separately connected to or coupled to the first radiator. A second end of the second radiator is disposed opposite to a second end of the third radiator, to form a gap. The antenna system feeds the first antenna through a first feeding connection point on the second radiator, and feeds the second antenna through a second feeding connection point on the third radiator. In this way, a new antenna system is constructed. In the system, high isolation between the first antenna and the second antenna can be implemented, and miniaturization of an antenna diameter and a low SAR value can be further implemented.

摘要： This application relates to an antenna and an electronic device. The antenna includes a patch radiator, a first ground point, and a second ground point. The patch radiator has a first side edge and a second side edge that intersect with each other, and has a first coupling contact and a second coupling contact. The patch radiator is coupled to the first ground point and the second ground point through the first coupling contact and the second coupling contact, to be grounded through the first ground point and the second ground point. The first coupling contact and the second coupling contact are disposed on the patch radiator at an interval, and a distance between the first coupling contact and the first side edge, a distance between the first coupling contact and the second side edge, a distance between the second coupling contact and the first side edge, and a distance between the second coupling contact and the second side edge are all greater than or equal to 0.05λ. According to a manner of disposing a ground point in this application, currents on the patch radiator can be evenly distributed around, to form an omnidirectional pattern. This reduces a directivity coefficient, and enables the antenna to have features such as a low SAR and high efficiency.

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.
