Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and 2, fig. 1 is one of top views of a transparent antenna provided in an embodiment of the present application, and fig. 2 is a second top view of the transparent antenna provided in the embodiment of the present application. As shown in fig. 1 and 2, the transparent antenna 100 includes: the antenna comprises a transparent substrate 110, a printed board substrate 120, a power distribution feeder 130 and N transparent radiation units 140, wherein N is a positive integer;
the power distribution feeder 130 is disposed on the printed board substrate 120, and the N transparent radiating units 140 are disposed on the transparent substrate 110;
a first side port of the power dividing feeder 130 is connected to the feed port 200 of the transparent antenna 100, and a second side port of the power dividing feeder 130 is connected to the N transparent radiating elements 140, respectively.
Specifically, the transparent substrate 110 may be a hard transparent substrate such as glass or the like; the substrate may also be a flexible transparent substrate, such as a transparent polymer substrate, specifically a Polyethylene Terephthalate (PET) substrate, a Polycarbonate (PC) substrate, and the like. The transparent substrate 110 and the printing board substrate 120 may be disposed on the same plane, or may be partially attached to different horizontal planes, which is not limited in this application.
The transparent substrate 110 may be provided with one or more transparent radiation units 140, which is not particularly limited in the present application. When there are a plurality of transparent radiation units 140, a plurality of transparent radiation units 140 may be disposed on one end surface or both end surfaces of the transparent substrate 110. Each of the transparent radiating elements 140 in the plurality of transparent radiating elements 140 is connected to the second side port of the power dividing feeder 130. In this way, each transparent radiating element 140 can receive the electromagnetic signal fed by the second side port of the power dividing feeder 130 and radiate the electromagnetic signal in the form of electromagnetic wave.
It should be noted that the power dividing feeder 130 is a signal transmission line with small sheet resistance, such as a copper foil type feeder. Therefore, compared with the conventional transparent antenna 100 using a feed line in the form of an ITO conductive film or a metal mesh, the power dividing feed line 130 is more difficult to generate heat in an operating state, and is less likely to burn out even when a high-power signal is fed. Moreover, the power dividing feeder 130 can perform power division on the power of the signal fed into the feed port 200 according to the number of the second side ports, so that the power of the signal fed into the transparent radiation unit 140 from the second side ports is also greatly reduced, and the transparent radiation unit 140 is prevented from being burned out.
In this embodiment, by additionally providing the printed board substrate 120 on the transparent antenna 100 and providing the power dividing feeder 130 with a small square resistance on the printed board substrate 120, the high-power signal input from the feed port 200 can be power divided by the power dividing feeder 130, so that the power fed to each transparent radiating element 140 is reduced. Therefore, compared with the conventional method in which the transparent antenna 100 directly feeds the signal input by the feed port 200 to the transparent radiation unit 140, the method in the embodiment of the present application is more beneficial to improving the power tolerance of the transparent antenna 100, so that the transparent antenna 100 has a wider signal coverage range and more application scenarios.
Further, the second side port of the power dividing feeder 130 includes N ports;
wherein the N ports are respectively connected to the N transparent radiating elements 140.
In an embodiment, the number of the second side ports of the power distribution feeder 130 corresponds to the number of the transparent radiating elements 140, and each port is connected to one transparent radiating element 140. The following is described in detail with reference to fig. 1 and 2, respectively:
as shown in fig. 1 of the two-element transparent antenna 100, 2 transparent radiating elements 140 are disposed on the transparent substrate 110, so that 2 ports need to be disposed at the second side port of the power dividing feeder 130, and the 2 transparent radiating elements 140 are respectively connected to the 2 ports of the second side port of the power dividing feeder 130. Assuming that the power margin of each transparent radiating element 140 is 10W and the signal power fed from the feeding port 200 is 20W, the power of 20W can be divided by the power dividing feeder 130, so that the power fed to each transparent radiating element 140 is 10W, so as to meet the requirement of the power margin of each transparent radiating element 140. In this way, the power margin of the transparent antenna 100 can be raised to 20W.
As shown in the four-element transparent antenna 100 in fig. 2, 4 transparent radiating elements 140 are disposed on the transparent substrate 110, so that 4 ports need to be disposed at the second side port of the power dividing feeder 130, and the 4 transparent radiating elements 140 are respectively connected to the 4 ports of the second side port of the power dividing feeder 130. In the same principle, assuming that the power margin of each transparent radiating element 140 is 10W and the signal power fed from the feeding port 200 is 40W, the power of 40W can be divided by the power dividing feeder 130, so that the power fed to each transparent radiating element 140 is 10W, thereby satisfying the power margin requirement of each transparent radiating element 140. In this way, the power margin of the transparent antenna 100 can be raised to 40W.
Of course, as another embodiment, the number of the transparent radiating elements 140 may be flexibly set, for example, to be 3, 5, or other numbers, so as to achieve different power tolerance requirements of the transparent antenna 100.
Further, N transparent radiation units 140 are disposed at equal intervals on the transparent substrate 110, and a distance between any two adjacent ports of the N ports matches a distance between any two adjacent transparent radiation units 140 of the N transparent radiation units 140.
In an embodiment, the N transparent radiation units 140 and the N ports may be arranged at equal intervals, which is beneficial for uniformly distributing each transparent radiation unit 140 on the transparent substrate 110, and each port in the second side ports of the power distribution feeder 130 is uniformly distributed on the printed board substrate 120, so as to avoid a short circuit occurring due to a close interval of a part of the transparent radiation units 140 or a part of the ports, and simultaneously, is beneficial for avoiding a crosstalk of electromagnetic signals on each branch.
Further, the N transparent radiating elements 140 include N transparent feed lines 1401 and N transparent antenna elements 1402;
first ends of the N transparent feed lines 1401 are connected to the N ports, respectively, and second ends of the N transparent feed lines 1401 are connected to the N transparent antenna elements 1402, respectively.
Specifically, a first end of each transparent feeder 1401 may be connected to one of the second side ports of the power dividing feeder 130, and configured to receive an electromagnetic signal transmitted by the power dividing feeder 130, and a second end of each transparent feeder 1401 may be connected to one transparent antenna element 1402, and configured to convert the electromagnetic signal into an electromagnetic wave and radiate the electromagnetic wave, so as to implement signal coverage in different directions.
Further, the first ends of the N transparent feeders 1401 are respectively connected with the N ports in a welding manner; or
The first ends of the N transparent feeder lines 1401 are respectively coupled with the N ports; or
The first ends of the transparent feeder 1401 of the first part of the N transparent feeders 1401 are respectively connected with the first part of the N ports by welding, and the first ends of the transparent feeder 1401 of the second part of the N transparent feeders 1401 are respectively connected with the second part of the N ports by coupling.
Specifically, the above-mentioned welding connection means that the first end of the transparent feeder 1401 is connected to the second side port of the power dividing feeder 130 by welding. The coupling connection comprises a contact coupling connection and a non-contact coupling connection, wherein the contact coupling connection means that the first end of the transparent feeder 1401 is closely attached to the second side port of the power dividing feeder 130 to realize coupling electric connection; the non-contact coupling connection means that the first end of the transparent feeder 1401 and the second side port of the power distribution feeder 130 are spaced by a preset distance to realize coupling electrical connection.
In an embodiment, the first ends of the N transparent feeders 1401 may be all connected to the second side port of the power dividing feeder 130 by welding; or may be connected to the second side port of the power distribution feeder 130 in a coupling manner; of course, it may also be connected to part of the second side port of the power distribution feeder 130 partially by soldering, and partially connected to part of the second side port of the power distribution feeder 130 by coupling. In this way, the connection mode between each transparent feeder 1401 and the power dividing feeder 130 is flexible, so that the flexibility of connection between the transparent substrate 110 and the printed board substrate 120 is also improved.
Further, N transparent radiation units 140 are disposed on the first end surface of the transparent substrate 110; or
The N transparent radiation units 140 are arranged on the second end face of the transparent substrate 110; or
A first part 140 of the N transparent radiating elements 140 is disposed on the first end surface of the transparent substrate 110, and a second part 140 of the N transparent radiating elements 140 is disposed on the second end surface of the transparent substrate 110;
the first end face and the second end face are two end faces of the transparent substrate 110 disposed opposite to each other.
In an embodiment, the transparent radiation units 140 may be disposed on one end surface of the transparent substrate 110, or disposed on two opposite end surfaces of the transparent substrate 110. In this way, it is advantageous to flexibly set the positions of the transparent radiating elements 140 according to the size of the transparent substrate 110 or the number of the transparent radiating elements 140 so as to meet different power tolerance requirements of the transparent antenna 100.
Further, the printed board substrate 120 is partially attached to the first end surface or the second end surface.
Referring to fig. 3, fig. 3 is a side view of a transparent antenna provided in an embodiment of the present application. As shown in fig. 3, the printed board substrate 120 may be partially attached to the first end surface of the transparent substrate 110. Of course, as another embodiment, the printed board substrate 120 may be partially attached to the second end surface of the transparent substrate 110. By partially attaching the printed substrate 120 to the transparent substrate 110, the connection between the transparent feeder 1401 and the power dividing feeder 130 can be better achieved, and at the same time, the overall size of the transparent antenna 100 can be reduced under the condition that the sizes of the transparent substrate 110 and the printed substrate 120 are fixed.
Further, the width of the printed board substrate 120 is smaller than the width of the first end surface or the second end surface.
In one embodiment, the width of the printed board substrate 120 is generally set to be in the millimeter order, which is much smaller than the width of the transparent substrate 110. In this way, even if the printed board substrate 120 is additionally provided to the transparent antenna 100, since the printed board substrate 120 itself is narrow, the width of the printed board substrate 120 is negligible compared to the entire width of the transparent antenna 100. This may, therefore, substantially reduce the effect of printed board substrate 120 on the overall transparent visual effect of transparent antenna 100.
Further, the power dividing feed line 130 is a microstrip line.
Since the microstrip line has advantages of small volume, light weight, wide frequency band, high reliability, low manufacturing cost, etc., the microstrip line is used as the power dividing feeder 130, so that the volume of the printed board substrate 120 on which the power dividing feeder 130 is disposed can be further reduced, and the broadband requirement of the transparent antenna 100 can be realized.
In addition, the present application also provides an electronic device including the transparent antenna 100 described above.
It should be noted that the specific embodiment of the electronic device is the same as the transparent antenna 100, and is not described herein again.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
