Detailed ways

The following describes the implementation of the present invention through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

Please refer to Figure 1 to Figure 42. It should be noted that the diagrams provided in this embodiment only illustrate the basic idea of the present invention in a schematic manner, so the diagrams only show the components related to the present invention instead of the number, shape, and shape of the components in actual implementation. For the size drawing, the type, quantity, and proportion of each component can be changed at will during actual implementation, and the component layout type may also be more complicated. For example, the number of signal lines of electronic functional devices is shown as two in the figure, but in actual cases it can be more than two. For example, in electronic functional devices such as sensors, the number of signal lines is 5-6 . In addition, for ease of understanding, only part of the signal lines of the electronic function device are shown in the figure. As common knowledge in the art, those of ordinary skill in the art will know that the specific length of the signal line of the electronic function device varies with the entire device. The position of the signal access terminal on the structure of the motherboard changes.

More and more electronic devices have begun to introduce wireless communication functions, and with the increasing integration of electronic devices, more and more severe tests are put forward to the compact space layout of the antenna unit; in addition, the electronic equipment provided by electronic equipment manufacturers The device layout design generally does not change according to the antenna unit design provided by the antenna unit supplier, which also poses a challenge to the compact design of the antenna unit. Based on this, the inventor analyzed various influencing factors in the prior art and proposed an integrated antenna unit design, as shown in FIG. 4, the antenna unit includes:

The continuous conductor 10 is arranged on at least one side of the electronic function device 13;

The AC power feeding module 11 is used to feed AC power to the continuous conductor 10;

The antenna is referenced to the ground 12 and is electrically connected to the AC feed module 11.

As shown in FIGS. 1 to 3, as an example, the continuous conductor 10 is provided on at least one side of the electronic function device 13. As shown in FIG. 1, the continuous conductor 10 may be arranged on the outer periphery of the electronic function device 13 to wrap the electronic function device 13 inside; the continuous conductor 10 may be arranged on the outer periphery of the electronic function device 13 On either side, as shown in FIG. 2, the continuous conductor 10 is arranged on the lower side of the electronic function device 13; as shown in FIG. 3, the continuous conductor 10 may be arranged on both sides of the electronic function device 13 And downside. The positional relationship between the continuous conductor 10 and the electronic functional device 13 can also be in other ways, and can be designed according to the specific situation of the antenna unit, which is not limited here.

It should be noted that the electronic functional device mentioned in the present invention refers to a device that needs to supply power to it and can realize certain electronic functions (such as light emission, power generation, generation, sensing, etc.), such as: light-emitting diodes, batteries , Microphone, USB, Speaker, proximity sensor (P-sensor), etc.

The AC power feeding module is used to feed AC power to the continuous conductor, so the AC power feeding method may be direct feeding by using an AC power source, or a radiator coupling feeding, which is not limited here. In addition, a person of ordinary skill in the art knows that, in order to achieve the performance of the antenna unit, in addition to the AC signal contained in the AC feed module, a corresponding impedance adjustment module (matching or other tuning device) will also be provided to achieve the impedance matching of the antenna unit. .

The antenna reference ground is used as a part of the antenna unit. In electronic equipment, it can usually be all conductive components such as a motherboard, a middle frame, a screen, an FPC, a bracket with a metal coating, and so on.

The present invention utilizes the inherent spatial position of the electronic functional device, by arranging a continuous conductor on at least one side of the electronic functional device, and using the continuous conductor as the resonant element and/or excitation source of the antenna unit, the wireless communication function of the antenna unit is realized, and at the same time Maintain the original performance of the electronic functional device unchanged, realize the design of the electronic functional device and the antenna unit at the same time in an environment with no antenna headroom or the smallest possible headroom, so that the electronic functional device and the antenna unit can be spatially reused, which is a further improvement for the electronic equipment. The high level of integration makes it possible.

As shown in FIG. 5, as an example, the integrated antenna unit design further includes a parasitic branch 14, one end of the parasitic branch 14 is electrically connected to the antenna reference ground 12, and the other end is suspended. Adding a parasitic branch to the antenna unit can achieve the purpose of widening the bandwidth of the antenna unit by coupling and superimposing the alternating current feed module with the continuous conductor's feeding branch and the parasitic branch branch. The opening direction of the parasitic branch and the relative position with the continuous conductor can be set according to the specific requirements of the designed antenna unit. As shown in FIG. 5, the parasitic branch is set on the lower side of the continuous conductor, and the opening is Towards the AC power feeding module. In addition, the parasitic branch may be designed at the same time when the antenna unit of the present invention is designed, or it may be included in the electronic device itself.

As an example, the continuous conductor 10 is arranged on at least one side of an electronic function device group composed of at least one electronic function device 13. When the size of the electronic function device is small, the size of the continuous conductor may not meet the antenna radiation requirement. At this time, it can be considered to form a group of electronic function devices with a plurality of electronic function devices in suitable positions nearby, and then set the continuous conductor On at least one side of the electronic function device group, it can meet the size requirements of antenna radiation; on the other hand, combining multiple electronic function devices as an electronic function device group can also simplify the complex structure between multiple electronic function devices and reduce The mutual influence between various electronic functional devices improves the performance of multiple electronic functional devices.

As an example, the continuous conductor 10 is electrically connected to other radiators. The other radiators may be antenna traces in the form of PCB, LDS, FPC, etc. In the same way, when the size of the continuous conductor may not meet the antenna radiation requirement, at this time, it may be considered to electrically connect other radiators at a suitable location near the continuous conductor to the continuous conductor to increase the antenna radiation area and meet the antenna unit size requirement.

What needs to be explained here are the above three situations, namely: the arrangement of the parasitic branch, the arrangement of the electronic functional device group and the arrangement of the electrical connection of the other radiators with the continuous conductor, which can be designed separately in the antenna unit or can be The combination design, specifically, is combined according to the specific requirements of the antenna unit design and the specific design layout of the electronic device, which is not limited here.
