Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.

Please refer to fig. 1 to 42. It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of each component in actual implementation may be changed arbitrarily, and the layout of the components may be more complicated. For example, the number of signal lines of the electronic function device is shown as two, but in the actual case, the number of signal lines may be more than two, for example, 5 to 6 in the electronic function device such as a sensor. In addition, for the convenience of understanding, only a part of the signal lines of the electronic functional devices are shown in the drawings, and as a common general knowledge in the field, a person skilled in the art can know that the specific length of the signal lines of the electronic functional devices varies with the position of the signal access terminals on the main board of the whole device structure.

More and more electronic devices begin to introduce wireless communication functions, and along with the higher and higher integration level of the electronic devices, more and more severe tests are provided for the compact spatial layout of the antenna unit; in addition, the electronic device layout design provided by the electronic device manufacturer is not generally changed according to the antenna unit design provided by the antenna unit provider, which also presents a challenge to the compact design of the antenna unit. Based on this, the inventor has analyzed various influencing factors of the prior art and proposed an integrated antenna unit design, as shown in fig. 4, the antenna unit comprises:

a continuous conductor 10 provided on at least one side of the electronic functional device 13;

an ac power feeding module 11 for feeding ac power to the continuous conductor 10;

the antenna is electrically connected to the ac power feeding module 11 with reference to the ground 12.

As shown in fig. 1 to 3, the continuous conductor 10 is provided on at least one side of the electronic functional device 13 as an example. As shown in fig. 1, the continuous conductor 10 may be disposed at the outer periphery of the electronic functional device 13 to enclose the electronic functional device 13 therein; the continuous conductor 10 may be disposed on either side of the electronic functional device 13, as shown in fig. 2, the continuous conductor 10 being disposed on the underside of the electronic functional device 13; as shown in fig. 3, the continuous conductor 10 may be disposed on both sides and the lower side of the electronic functional device 13. The position of the continuous conductor 10 and the electronic functional device 13 may be set in other manners, and may be designed according to the specific situation of the antenna unit, which is not limited herein.

It should be noted that the electronic functional device mentioned in the present invention refers to a device that needs to be powered and can realize some electronic functions (such as light emitting, power generating, sensing, etc.), for example: light emitting diodes, batteries, microphones, USB, Speaker, proximity sensors (P-sensors), etc.

The alternating current feeding module is configured to feed alternating current into the continuous conductor, so that the alternating current can be directly fed by using an alternating current feeding source, or fed by using a radiator in a coupling manner, which is not limited herein. In addition, as known to those skilled in the art, in order to implement the performance of the antenna unit, the ac feeding module may also include an impedance adjusting module (matching or other tuning device) to implement impedance matching of the antenna unit.

The antenna is referred to as a part of an antenna unit, and in an electronic device, the antenna unit may be generally any conductive component such as a main board, a middle frame, a screen, an FPC, a metal-coated bracket, and the like.

The invention utilizes the inherent space position of the electronic function device, realizes the wireless communication function of the antenna unit by arranging the continuous conductor on at least one side of the electronic function device and taking the continuous conductor as the resonance element and/or the excitation source of the antenna unit, simultaneously keeps the original performance of the electronic function device unchanged, realizes the design of the electronic function device and the antenna unit under the environment without antenna clearance or with the smallest clearance as possible, realizes the spatial multiplexing of the electronic function device and the antenna unit, and provides possibility for further high integration of electronic equipment.

As shown in fig. 5, the integrated antenna unit design further includes a parasitic stub 14, and one end of the parasitic stub 14 is electrically connected to the antenna reference ground 12 and the other end is floating. The parasitic branch is added in the antenna unit, and the purpose of widening the bandwidth of the antenna unit can be achieved by coupling and superposing the alternating current feed module with the feed branch and the parasitic branch of the continuous conductor. The opening direction of the parasitic branch and the relative position with the continuous conductor may be set according to the specific requirements of the designed antenna unit, as shown in fig. 5, the parasitic branch is disposed at the lower side of the continuous conductor, and the opening faces the ac power feeding module. In addition, the parasitic stub may be designed simultaneously when the antenna unit of the present invention is designed, or may be provided in the electronic device itself.

As an example, said continuous conductor 10 is arranged on at least one side of a group of electronic functional devices consisting of at least one of said electronic functional devices 13. When the size of the electronic functional device is small, the size of the continuous conductor may not meet the antenna radiation requirement, and at this time, it may be considered that a plurality of electronic functional devices in suitable positions nearby the electronic functional device form an electronic functional device group, and then the continuous conductor is disposed on at least one side of the electronic functional device group to meet the size requirement of the antenna radiation; on the other hand, the combination of a plurality of electronic functional devices as the electronic functional device group can simplify the complex structure among the plurality of electronic functional devices, reduce the mutual influence among the electronic functional devices and improve the performance of the plurality of electronic functional devices.

As an example, the continuous conductor 10 is electrically connected to other radiators. The other radiators can be antenna traces in the forms of PCBs, LDS, FPCs, and the like. Similarly, when the size of the continuous conductor may not meet the antenna radiation requirement, it may be considered to electrically connect other radiators at suitable positions near the continuous conductor to increase the antenna radiation area and meet the antenna unit size requirement.

Here, the above three cases are to be explained, that is: the arrangement of the parasitic stub, the arrangement of the electronic function device group, and the arrangement of the other radiators electrically connected with the continuous conductor may be designed separately or in combination in the antenna unit, specifically, the combination is performed according to the specific requirements of the antenna unit design and the specific design layout of the electronic device, which is not limited herein.

The integrated antenna unit design of the present invention will be described in detail with reference to the specific drawings and the corresponding embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
