All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1 to fig. 6, the present application provides an antenna assembly, preferably an MDA antenna suitable for electronic devices such as mobile phones, which mainly includes an antenna body 1, a carrier 2 and a mounting member 4, wherein: in terms of structure, the antenna body 1 is connected to the carrier 2 by injection molding to be carried by the carrier 2, the carrier 2 is connected to the mounting member 4, and then the mounting of the whole antenna assembly in the electronic device is realized by the matching installation of the mounting member 4 and other components of the electronic device, the antenna body 1 further comprises a plurality of functional parts 101 connected to the carrier 2 by injection molding, and an auxiliary part 102 connected to all the functional parts 101 before the carrier 2 is injection molded and removed after the carrier 2 is injection molded, the functional parts 101 are components of the antenna assembly for receiving and transmitting signals, and the auxiliary part 102 is used for connecting and supporting the plurality of functional parts 101, since the functional parts 101 are connected to the carrier 2 by injection molding, the plurality of functional parts 101 need to be placed at corresponding positions in the injection mold first during the injection molding process, then plastic material is injected into the injection mold, and the auxiliary part 102 is arranged to connect, The functional parts 101 can be prevented from moving in the injection process of the plastic raw material by supporting the functional parts 101, so that the functional parts 101 and the bearing part 2 can be connected in an injection molding manner according to the process requirement; in terms of material, the metal activity of the material for manufacturing the antenna body 1 is made to be weaker than that of the reference material, so that the antenna body 1 is less prone to be oxidized relative to the reference material, the resistance of the feed point of the antenna body 1 is not excessively increased or even not increased due to the fact that the material is prone to be oxidized, and therefore the stability of the working performance of the antenna body 1 can be improved, meanwhile, the density of the metal material for manufacturing the mounting part 4 is not greater than that of the reference material, so that the mass of the mounting part 4 is not increased relative to that of the reference material on the premise of the same volume, and the mounting part 4 is the light mounting part 4, while the reference material defined in the application is a light material which is commonly used for manufacturing MDA antenna in the prior art and has stronger metal activity, such as magnesium aluminum alloy, on the basis, the material of the antenna body 1 can be aluminum or aluminum alloy and the like, the material of the mounting member 4 may be magnesium aluminum alloy, magnesium lithium alloy, carbon fiber, glass fiber board, or the like. In addition, in addition to the definition of the density of the mounting member 4, the present application may also preferably select that the yield strength of the metal material of the mounting member 4 is greater than that of the reference material, so that the mounting member 4 has greater strength and is less prone to deformation, and the mounting stability and firmness of the carrier member 2 and other components of the electronic device on the mounting member 4 are ensured.
