The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
In the description of the embodiments of the present application, it should be understood that the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the embodiments of the present application, "a plurality" means two or more unless specifically defined otherwise.
The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known processes have not been described in detail so as not to obscure the description of the embodiments of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the embodiments herein.
The embodiment of the application provides an antenna communication device, an antenna device connection detection method, a terminal and a storage medium. The antenna communication device can be installed in terminals such as mobile phones and intelligent panels, and a control chip in the terminal can send out control signals to execute the antenna device connection detection method and detect the connection condition in the antenna communication device.
Referring to fig. 1, fig. 1 shows an installation of an antenna communication device in a terminal, and an arrow direction indicates a transmission direction of a detection signal. The terminal 100 may further include an antenna communication device 110. The antenna communication device 110 is used for implementing a Wireless communication function of the terminal 100, for example, the antenna communication device 110 may transmit a Wireless Fidelity (Wi-Fi) signal, a Global Positioning System (GPS) signal, a third Generation mobile communication technology (3th-Generation 3G), a fourth Generation mobile communication technology (4th-Generation 4G), a fifth Generation mobile communication technology (5th-Generation 5G), a Near Field Communication (NFC) signal, and the like; for another example, the antenna communication device 110 may also implement a UWB communication function. The antenna communication device 110 may be disposed inside a housing of the terminal 100. It is understood that some components of the antenna communication device 110 may be integrated on the circuit board 130, for example, a signal processing chip and a signal processing circuit in the antenna communication device 110 may be integrated on the circuit board 130, so as to electrically connect the antenna communication device 110 and the circuit board 130. In addition, some components of the antenna communication device 110 may be directly disposed inside the terminal 100. For example, an antenna radiator or conductor structure for radiating signals by the antenna communication device 110 may be provided directly inside the terminal 100.
The antenna communication device 110 includes an antenna radiator 210, a feed 220, an antenna connection 230, and a detection module 240. The antenna radiator 210 is connected to the feed 220 through an antenna connection 230, and the antenna radiator 210 is grounded through the antenna connection 230. The detection module 240 is coupled to the antenna connection 230. The detection module 240 is used for detecting the connection between the antenna radiator 210 and the antenna connector 230.
The antenna radiator 210 may be a radiator made of a conductive material, such as metal, conductive cloth, or the like. The shape of the antenna radiator 210 is not particularly limited in the embodiment of the present application, and for example, the shape of the antenna radiator 210 may be a rod, a strip, an ellipse, or the like.
Specifically, the antenna radiator 210 may include a feeding terminal 211 and a grounding terminal 212, and in order to avoid conduction due to a short circuit between the feeding terminal 211 and the grounding terminal 212 when signal communication is performed, the feeding terminal 211 and the grounding terminal 212 may be spaced apart from each other, for example, a gap value of a preset length may be set between the feeding terminal 211 and the grounding terminal 212. The feed terminal 211 is indirectly connected to the feed 220 through a connection member so that the feed 220 can transmit a wireless signal to the antenna radiator 210. The ground terminal 212 is also indirectly connected to the ground plane 250 through a connector to ground the antenna radiator 210.
The feed source 220 may be disposed on the circuit board 130 of the electronic device 110, and the feed source 220 may also be disposed on other small boards of the electronic device 110. The feed 220 may feed a wireless signal into the antenna radiator 210, and the antenna radiator 210 may transmit the wireless signal to a free space.
It is understood that other feed terminals may be provided on the radiator 220 in addition to the feed terminal 211 and the ground terminal 212 to electrically connect the antenna radiator 210 to other electronic devices.
The antenna connection member 230 may be made of a conductive material, for example, the antenna connection member 230 may be made of bronze. The shape of the antenna connection member 230 is also not particularly limited in the embodiments of the present application, for example, the antenna connection member 230 may be a connection member made in the form of a spring sheet.
In particular, the antenna connection 230 is used to connect the antenna radiator 210 and the feed 220, and to connect the antenna radiator 210 and the ground plane 250. In addition, the antenna connection member 230 may also prevent the wireless signal from overflowing. In the antenna communication device 110, the antenna connection element 230 may be an integrated connection element, that is, the antenna radiator 210 is connected to the feed 220 and the ground plane 250 through one connection element, and the antenna connection element 230 may further include a plurality of connection elements, for example, when only one feed terminal 211 and one ground terminal 212 are provided on the antenna radiator 210, the antenna connection element 230 may include one connection element for connecting the antenna radiator 210 and the feed 220 and one connection element for connecting the antenna radiator 210 and the ground plane 250.
The detecting module 240 is configured to send a high-level and direct-current detection signal, detect a level state of the detection signal between the feed 220, the antenna connector 230, and the transmission circuit of the antenna radiator 210, and determine whether the connection between the antenna connector 230 and the antenna radiator 210 is abnormal according to the level state. It should be noted that the part of the detection module 240 that sends out the detection signal and the part that detects the level state may be integrated, or may be two separate parts. Illustratively, the detection module 240 may be an integrated module capable of simultaneously emitting a detection signal and detecting a level state, and may further include two parts, i.e., a signal generator and a signal detector, for example, the detection module 240 may simultaneously include a power management chip for emitting a signal and a baseband chip for detecting a level state.
It should be noted that the detection signals are usually high-level and direct-current signals, and therefore, the details are not described below. The type of detection signal, however, should not be construed as limiting the embodiments of the present application.
Referring to fig. 2, specifically, the work flow of the antenna communication device 110 in the embodiment of the present application may include the following specific steps:
301. a detection module in the antenna communication device generates a detection signal and sends the detection signal to an antenna connecting piece.
302. The detection module detects the level state of the detection signal in the transmission circuit, wherein the transmission circuit comprises a feed source, the antenna connecting piece and an antenna radiating body.
303A, if the level state is a high level state, the detection module determines that the connection between the antenna connection member and the antenna radiator is abnormal.
303B, if the level state is a low level state, the detection module determines that the connection between the antenna connection member and the antenna radiator is normal.
When the antenna communication device 110 operates, the control chip in the terminal 100 may control the detection module 240 to send out a detection signal, where the detection signal is transmitted to the antenna radiator 210 through the antenna connector 230, and then transmitted to the ground plane 250 through the antenna connector 230. Therefore, when the detection module 240 detects that the detection signal between the transmission circuits is in a high level state, it indicates that the antenna radiator 210 is abnormally connected to at least one of the feed 220 and the ground plane 250, so that the detection signal cannot be transmitted into the antenna radiator 210 or the ground plane 250. When the detection signal is in a low level state, which indicates that the connection in the transmission circuit is good, the detection signal may be transmitted to the antenna radiator 210 through the antenna connection member 230, and then transmitted to the ground plane 250 through the antenna connection member 230.
Specifically, the connection abnormality may be caused by a poor contact between the antenna connection member 230 and the antenna radiator 210 or a failure in signal transmission due to a damage of the antenna connection member 230. The connection abnormality may include the above-mentioned situation, and is not described in detail.
To sum up, the antenna communication device provided in the embodiment of the present application includes: the antenna comprises an antenna radiator, a feed source, an antenna connecting piece and a detection module; the antenna radiator is connected with the feed source through the antenna connecting piece, and the antenna radiator is grounded through the antenna connecting piece; the detection module is connected with the antenna connecting piece; the detection module is used for sending a high-level detection signal so as to detect the connection condition between the antenna radiator and the antenna connecting piece. When the detection module detects that the detection signal between the feed source, the antenna connecting piece and the transmission circuit of the antenna radiator is in a high level state, the detection signal indicates that the antenna radiator is connected abnormally with at least one of the feed source and the ground plane, so that the detection signal cannot be transmitted into the antenna radiator or the ground plane, therefore, the antenna communication device can identify all abnormal connection conditions, and the defective product identification rate is high.
Referring to fig. 3, fig. 3 is another embodiment of an antenna communication device. In the antenna communication device 310 of fig. 3, the antenna connection 430 includes a feed connection 431 and a ground connection 432. The feed source 420, the feed connector 431 and the antenna radiator 410 are connected in sequence; the detection module 440 is connected with the feed connector 431; the antenna radiator 410 is connected to the ground plane 450 by a ground connection 432.
Wherein, one end of the feed connector 431 is connected to the feed terminal 411 of the antenna radiator 410, and the other end is connected to the feed source 420. Ground connector 432 has one end connected to ground 412 on antenna radiator 410 and one end connected to ground plane 450.
Referring to fig. 4, specifically, the level state of the detection signal may include a first level state of the detection signal between the feed source 420 and the feed connection 411, and the work flow of the antenna communication device 310 in the embodiment of the present application may include the following specific steps:
501. a detection module in the antenna communication device generates a detection signal and sends the detection signal to an antenna connecting piece.
502. The detection module detects the level state of the detection signal in the transmission circuit.
503A, if the first level state is a high level state, the detection circuit determines that the connection between at least one of the feed connector and the ground connector and the antenna radiator is abnormal.
503B, if the first level state is a low level state, the detection circuit determines that the feed connector and the ground connector are both normally connected to the antenna radiator.
When the antenna communication device 310 operates, the control chip in the terminal 400 may control the detection module 440 to send out a detection signal, and the detection signal is transmitted to the feeding terminal 411 of the antenna radiator 410 through the feeding connector 431, then transmitted to the ground terminal 412, and then transmitted to the ground plane 450 through the ground connector 432. Therefore, when the first level state between the feed source 420 and the feed connector 411 is a high level, it indicates that at least one of the feed connector 431 and the ground connector 432 is abnormally connected to the antenna radiator 410, so that the detection signal does not flow into the ground plane 450. When the first level state is a high level state, it indicates that the detection signal can flow into the ground plane 450, and thus the feed connection 431 and the ground connection 432 are both normally connected to the antenna radiator 410.
In order to be able to distinguish the connection abnormality of the feed connection member from the connection abnormality of the ground connection member, the position of the signal detection section in the detection module may be changed. Referring to fig. 5, fig. 5 is another embodiment of an antenna communication device. In the antenna communication device 510 of fig. 5, the antenna connection 630 includes a feed connection 631 and a ground connection 632. The feed source 620, the feed connector 631 and the antenna radiator 610 are connected in sequence; the antenna radiator 610 is connected to the ground plane 650 by a ground connector 632; the detection signal generating part 641 of the detection module 640 is connected to the feeding connector 631; the signal detection part 642 of the detection module 640 is connected to the antenna radiator 610.
The detection signal generating unit 641 may be any unit capable of generating a detection signal, and for example, the detection signal generating unit 641 may be a power control chip of the terminal 600. The signal detection section 642 may be any section capable of detecting a signal level state, and for example, the signal detection section 642 may be a baseband chip (hereinafter, referred to as BB chip) for detecting a signal level state.
Referring to fig. 6, specifically, the level state of the detection signal may include a second level state at the antenna radiator 610, and the work flow of the antenna communication device 510 in the embodiment of the present application may include the following specific steps:
701. a detection module in the antenna communication device generates a detection signal and sends the detection signal to an antenna connecting piece.
702. The detection module detects the level state of the detection signal in the transmission circuit.
703A, if the second level state is a high level state, the detection module determines that the connection between the ground connection connector and the antenna radiator is abnormal.
703B, if the second level state is a low level state, the detection module determines that the ground connection connector and the feed connection connector are both normally connected to the antenna radiator.
When the antenna communication device 510 operates, the control chip in the terminal 600 may control the detection signal generating component 641 to emit a high-level detection signal, and the detection signal is transmitted to the feeding end 611 of the antenna radiator 610 through the feeding connector 631, then transmitted to the ground end 612, and then transmitted to the ground plane 650 through the ground connector 632. The signal detection part 642 connected to the antenna radiator 610 may detect a second level state of the detection signal at the antenna radiator 610 during operation.
Specifically, if the second level state is a high level state, it means that the sensing signal flows into the antenna radiator 610 through the feed connector 631, but is disconnected at the ground terminal 612 and cannot flow into the ground plane 650. It is therefore possible to determine that the connection between the ground connector 632 and the antenna radiator 610 is abnormal at this time.
If the second level state is a low level state, it means that the sensing signal can flow into the antenna radiator 610 through the feed connector 631 and into the ground plane 650 through the ground connector 632. It can be determined that the feed connector 631 and the ground connector 632 are normally connected to the antenna radiator 610 at this time.
If the signal detecting part 642 does not detect any signal, it means that the detected signal does not flow into the antenna radiator 610 through the feed connection 631. It is possible to determine that the connection between the feed connector 631 and the antenna radiator 610 is abnormal at this time.
Further, when no signal is detected by the signal detecting section 642, it is also possible that the connection between the feed connector 631 and the detection signal generating section 641 is abnormal or that the detection signal generating section 641 is damaged and does not emit a detection signal. Therefore, the detection module 640 may further include a second signal detection unit (not shown in the figure), or a detection signal generation unit 641 capable of detecting a level state may be adopted to detect the first level state while detecting the second level state, so as to determine the cause of the abnormal connection by integrating the level states on both sides of the power supply connector 631.
Specifically, when the first level state is a high level and the signal detection part 642 connected to the antenna radiator 610 does not detect any signal, it indicates that the detection signal has flowed to the feed connector 631 but has not flowed into the antenna radiator 610 through the feed connector 631. It is possible to determine that the connection between the feed connector 631 and the antenna radiator 610 is abnormal at this time.
When the second signal detecting part (not shown in the drawing) connected to the feed connector 631 does not detect any signal at this time, and the signal detecting part 642 connected to the antenna radiator 610 does not detect any signal, it indicates that the connection between the feed connector 631 and the detection signal generating part 641 is abnormal, or the detection signal generating part 641 is damaged and does not emit a detection signal.
An antenna matching module for matching impedance is further included in the antenna communication device, and referring to fig. 7, in the antenna communication device 710, one end of the antenna matching module 860 is connected to the feed 820, the other end is connected to the antenna connector 830, the antenna connector 830 is connected to the antenna radiator 810, and the antenna radiator 810 is connected to the ground plane 850. In order to avoid the detection signal from the detection module flowing back to the feed source and the detection signal pulled low by the inductor (not shown in the figure) connected in parallel with the antenna matching module 860, a blocking capacitor 870 may be connected between the antenna matching module 860 and the antenna connector 830. Since the blocking capacitor 870 is considered as an open circuit when a dc detection signal is used, the detection signal neither flows into the feed 820 nor is pulled down by the inductor. The capacitance value of the blocking capacitor is not limited in the embodiment of the application, and a suitable blocking capacitor can be selected according to experience or experiments, for example, a capacitor with a capacitance value of about 33pf or more than 33pf can be used as the blocking capacitor.
In some embodiments, a protection resistor may be connected in series between the detection module and the antenna connection element to prevent the detection signal and the excitation signal from the feed source from interacting. The protective resistor is usually relatively large in resistance value, and a resistor having a resistance value of about 10kohm or more may be selected as the protective resistor. It should be noted that, if the antenna communication device 310 in fig. 3 needs to access the protection resistor, the accessed position is between the detection module 440 and the feeding connection 431.
