Problems solved by technology
However, due to the metal object connected to the feed unit and used for coupling feed, such as flexible circuit board FPC, laser direct forming LDS, etc., limited by the shape of the bracket, it cannot be as close as possible to the radiator of the metal strip antenna, which will also lead to insufficient coupling , the distributed capacitance is too small, and the low-frequency resonance frequency point does not meet the demand

The invention discloses an electronic device integrating an antenna feed unit, a tuning unit and a display screen assembly. The electronic device comprises the display screen assembly, a metal middleframe, a control circuit and a battery. The display screen assembly comprises a protection plate, a touch screen module, a display module and a flexible circuit board. The flexible circuit board is provided with a first protruding portion region, a second protruding portion region, a transmission line portion and a connector for connecting the flexible circuit board to a main board of the electronic device. The first protruding portion region is provided with the antenna feed unit and an antenna aperture tuning unit I. The transmission line portion comprises a radio frequency line, a control line I and a control line II. The radio frequency line, the control line I and the control line II are arranged on the inner layer of the flexible circuit board, wherein the flexible circuit board forms a strip line structure with copper coated layers on the front and back surfaces of the flexible circuit board. The electronic device improves system integration level, reduces the printed circuit board PCB required by an antenna and improves aperture tuning position flexibility.
Description
Technical field [0001] The invention relates to an electronic device, in particular to an electronic device in which an antenna feed unit, a tuning unit and a display screen assembly are combined. Background technique [0002] At present, with the development of mobile communication technology, the functions of electronic devices such as smart phones are becoming more and more abundant, and their roles in life are becoming more and more important. However, as the size of electronic devices tends to be thinner and lighter, the screen-to-body ratio is constantly increasing, and the distance between the display assembly and the electronic device housing is shrinking, resulting in smaller and smaller antenna headrooms and increasing performance. Bad, unable to meet the upcoming 5G communication era, the increase in the number of frequency bands and the large-scale antenna Massive MIMO for the increase in the number of antennas. In order to maximize the distance between the antenna a...
