Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
At present, with the development of 5G (fifth generation mobile communication), the design of millimeter wave antennas is gradually introduced to some small electronic devices, such as mobile phones, tablets, notebook computers, and the like, so that the effective radiation space obtained by each antenna is reduced while maintaining the competitive size of the whole system, and further, the performance of the antenna is reduced, which causes the degradation of the wireless experience of users. Or, in order to accommodate a plurality of discrete antennas, the overall size of the system is increased, so that the overall competitiveness of the product is reduced. The millimeter wave antenna is often in the form of an independent antenna module, and the millimeter wave antenna and an existing antenna, such as a cellular (cellular) antenna, and a non-cellular (non-cellular) antenna, are often separately disposed, so that the overall size of the system is easily increased, and the overall competitiveness of the product is reduced.
In addition, the currently planned 5G millimeter wave band includes n257(26.5-29.5GHz), n258(24.25-27.5GHz), n261(27.5-28.35GHz), and n260(37.0-40.0GHz) with 39GHz as the main frequency band. There is a roaming requirement in the frequency dimension in addition to the above-mentioned space dimension requirement for wireless performance. The main antenna elements of the millimeter wave antenna module, such as patch antenna, Yagi-Uda, or dipole antenna, are all narrow-band antennas, for example, the relative bandwidth of patch generally does not exceed 8%, and the millimeter wave frequency band usually requires broadband dual-band or multi-band form, which brings great challenges to the design of the millimeter wave antenna module. In order to meet the requirements of broadband, dual-frequency and even multi-frequency, for the patch, a slot is often required to be formed on a radiating plate of the patch or a stacked structure is adopted, which is often difficult to realize dual polarization or increase the thickness of the millimeter wave antenna module, so that the miniaturization and the whole machine integration of the millimeter wave antenna module are not facilitated.
At present, the antenna design scheme of the mainstream millimeter wave mainly adopts the technology and process of packaging the antenna, that is, the millimeter wave array antenna, the Radio Frequency Integrated Circuit (RFIC) and the Power Management Integrated Circuit (PMIC) are integrated into one module, and the module is arranged inside the mobile phone and occupies the space of other antennas, which causes the performance of the antenna to be reduced, thereby affecting the wireless experience of the user. Therefore, the embodiment of the invention provides an antenna unit and an electronic device, which not only can eliminate the influence of a metal plate on an antenna and improve the wireless experience of multiple frequency bands of a user during global roaming, but also have an MIMO function to improve the transmission rate of data, can form dual polarization, increase the wireless connection capacity of an array antenna, reduce the probability of communication disconnection, and improve the communication effect and the user experience.
