Abstract: An antenna equipment includes an antenna and a board on which the antenna is disposed, and includes an area that is disposed on the board and that is not covered by a metal layer. A first edge of the board is a longer edge of the board in two edges of the board that are close to the antenna, a point that is on the first edge and whose distance with a current maximum point on the first edge is λ/4 is a first point, the current maximum point is on the first edge and that is closest to a feed point of the antenna, and λ is an operating wavelength of the antenna. The area that is not covered by a metal layer includes the first point, and a maximum distance from an edge of the area to the first edge of the board is λ/4.

Abstract: An antenna assembly includes a first radiator, a second radiator, a feeding structure, and a decoupling apparatus. The first radiator includes a first radiation branch and a second radiation branch that have opposite bending directions, and a first gap exists between the first radiation branch and the second radiation branch. The second radiator includes a third radiation branch and a fourth radiation branch that have opposite bending directions, and a second gap exists between the third radiation branch and the fourth radiation branch. The feeding structure is electrically coupled to the first radiation branch and the third radiation branch. The first radiator and the second radiator share a common part, the common part is a common branch, and the common branch is electrically coupled to a grounding terminal of the antenna assembly through the decoupling apparatus.

Abstract: A Near-Field Communication (NFC) antenna and an electronic apparatus include a metal structure on a personal computer (PC), an inductor, a capacitor, and an NFC chip. One end of the metal structure on the PC is coupled to one end of the inductor. The other end of the inductor is coupled to one port of the NFC chip and one end of the capacitor. The other end of the metal structure on the PC is coupled to the other port of the NFC chip and the other end of the capacitor.
