Abstract: This application relates to the field of antenna technologies, and in particular, to an antenna assembly. The antenna assembly includes a first antenna array element, a second antenna array element, and a filtering structure. The first antenna array element supports receiving in a first frequency band, and the second antenna array element supports transmitting in a second frequency band. The filtering structure includes at least one of a first filtering structure and a second filtering structure. The first filtering structure is disposed on the first antenna array element, and the second filtering structure is disposed on the second antenna array element. Isolation of the antenna assembly is high.

Abstract: A backplane structure includes: a backplane; an electronic board having a plurality of first through-holes and a plurality of second through-holes spaced apart from the plurality of the first through-holes, the first through-holes each having a rectangular cross section; a plurality of strutting components, a plurality of connecting pieces, and a plurality of locking components, wherein the plurality of strutting components and the plurality of locking components are both disposed at positions corresponding to the second through-holes and the first through-holes on the backplane, respectively, the plurality of strutting components are fixedly connected to the electronic board via the plurality of connecting pieces, each of the locking components includes an inwardly concave locking slot disposed in a side surface of the locking component perpendicular to the backplane, and each of the locking components is locked with the electronic board via each of first through-holes.

Abstract: A fixing device for a circuit board and an electronic apparatus including the fixing device, related to the display field, and can be applied for the fixation of circuit boards with different sizes and structures onto a component to be fixed. The fixing device for a circuit board includes: a holding portion, used to hold a circuit board and including a containing space and a top portion including an opening allowing the circuit board to pass through the opening and to be inserted in the containing space; and a fixing portion, connected with the bottom portion of the holding portion and configured to fix on the display device. Also, an electronic apparatus including at least one fixing device for a circuit board is disclosed.

Abstract: The present disclosure provides an identity authentication method and apparatus and a server. Embodiments may avoid inconvenience of input of authentication information via the input device and easy occurrence of errors in the prior art and thereby improve efficiency and reliability of identity authentication in the following manner: the authentication end encrypts the obtained token with a private key to obtain a signature so that the authentication end can send to the server the first identity identifier, the token and the signature generated according to the public key corresponding to the private key such that the server obtains the second identity identifier according to the token and the signature, and performs identity authentication according to the first identity identifier and the second identity identifier.
