Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
The antenna provided by the embodiment of the present invention may be applied to a wireless communication device, such as a mobile terminal, e.g., a mobile phone or a tablet computer, and for convenience of description, the following embodiments take a mobile phone as an example for description.
For the integral beauty of the mobile phone, the antenna of the mobile phone is hidden in the mobile phone body, and for the mobile phone with the metal frame, the metal frame of the mobile phone can be used as the antenna to realize the receiving and sending of signals.
All be equipped with the USB interface on the cell-phone, the effect of USB interface is as the interface that charges on the one hand, and on the other hand is as data transmission interface.
Because the USB interface made of metal is disposed near the metal frame of the mobile phone, that is, the USB interface made of metal is disposed near the mobile phone antenna, the metal often interferes with the function of transmitting and receiving signals of the antenna.
Therefore, in order to ensure that the antenna of the mobile phone can normally transmit and receive signals, the USB interface of the mobile phone is generally spaced from the antenna by a predetermined distance, and the USB interface is isolated from the antenna.
In addition, in order to achieve better quality of the antenna transmitting and receiving signals, the metal frame used as the antenna at present adopts a metal slotted design. However, the metal frame of the mobile phone is designed to be slit, so that the metal frame needs to be slit, and on the other hand, the slit part needs to be filled with a non-metal material for the sake of good appearance, and such a manufacturing process causes a high cost of the mobile phone.
According to the antenna provided by the invention, the first radiator and the USB interface are integrally designed, so that the influence of the USB interface on the antenna signal is eliminated, namely the USB interface is set as the first radiator of the antenna, and the USB interface can realize the functions of receiving and sending signals by the antenna, so that the interference of the metal shell of the USB interface on the receiving and sending signals of the antenna is eliminated.
In addition, the antenna provided by the invention has the advantages that the second radiator is set to be the closed-loop metal frame, and the metal shell of the USB interface is connected with the second radiator. On the basis of eliminating the influence of the USB interface metal shell on the antenna receiving and transmitting signals, the design of a metal frame closed loop is realized, and reasonable adjustment is carried out on the position of the corresponding receiving and transmitting structure of the antenna, so that the closed loop metal frame can also achieve the effect of better receiving and transmitting signals.
Example one
Fig. 3 is a schematic structural diagram of an embodiment of the antenna provided in the present invention.
The antenna provided by the embodiment comprises: a first radiator 301 and a second radiator 302.
The second radiator 302 is a closed-loop metal frame without slits.
The first radiator 301 is a USB interface.
The metal shell of the USB interface 301 is connected to the second radiator 302 through metal.
As shown in fig. 3, the antenna provided in this embodiment is designed to integrate the first radiator 301 with the USB interface, that is, the USB interface can be used as the first radiator to transmit or receive signals in addition to performing operations such as data transmission and device charging. Due to the integrated design, the influence of the original USB interface metal shell on the antenna receiving and transmitting signals is eliminated.
It should be noted that, in this embodiment, the material of the first radiator 301 and the second radiator 302 is not specifically limited, and may be selected according to actual needs.
In this embodiment, the second radiator 302 is designed as a closed-loop metal frame without a slot, and the metal shell of the USB interface is connected to the metal of the second radiator 302. Due to the integrated design of the first radiator 301 and the USB interface, the large interference of the original USB interface metal shell to the antenna is eliminated. On this basis, even if the metal frame is designed to be a closed loop, the second radiator can also realize good signal receiving and sending, and if the positions of the structures of all the parts of the antenna are adjusted, the second radiator can achieve a good signal receiving and sending effect. In addition, the manufacturing cost required by the metal frame seam-breaking process is higher, and the production and manufacturing cost of the mobile phone frame is greatly saved by carrying out closed-loop design on the metal frame.
The metal shell of the USB interface 301 is connected to the second radiator metal frame 302, so that the normal implementation of the USB interface function is ensured, that is, the USB interface is connected to the device metal frame, so that the external device can be connected to the USB interface, the normal transmission of data between devices is ensured, and the basic functions of the USB interface, such as normal charging, of the devices are ensured.
As shown in fig. 3, the metal shell of the USB interface 301 is connected to the middle position of the bottom side of the second radiator 302.
That is, the metal shell of the USB interface 301 may be disposed at the middle position of the bottom edge of the second radiator 302, and of course, the USB interface 301 may be disposed at any position on the metal frame of the second radiator 302 according to different design requirements, which is not limited in this respect.
It is understood that the USB interface 301 may be separately provided, and the metal shell of the USB interface 301 and the second radiator 302 are connected through metal. The metal shell of the USB interface 301 and the second radiator 302 may also be integrally formed, i.e. integrated.
The metal shell of the USB interface can be connected to the metal of the second radiator 302, and in the design process, the metal shell of the USB interface and the second radiator can be directly designed in an integrated manner, that is, the metal shell of the USB interface and the second radiator are designed as a whole, so that the normal implementation of the function of the USB interface can be ensured, and in the production process, the connection steps between the metal shell of the USB interface and the metal of the second radiator can be reduced, and the production process is accelerated.
The antenna that this embodiment provided through carrying out the integrated design with USB interface and first irradiator, has eliminated among the prior art USB interface and has received and dispatched the interference that signal produced to the antenna, on this basis, further designs the closed loop metal frame that does not have the seam with the second irradiator to be connected the metal casing of USB interface and second irradiator metal, on the basis of guaranteeing the normal function of USB interface, practiced thrift manufacturing cost.
Example two
In order to achieve a better effect of transmitting and receiving signals by the antenna, the antenna feed point is further disposed in the middle of the bottom edge of the second radiator. Referring to fig. 4, a schematic structural diagram of another embodiment of the antenna provided by the present invention is shown.
The antenna provided by the embodiment further comprises: an antenna feed point 403.
As shown in fig. 4, the antenna feed point 403 may be disposed at a middle position of a bottom side of the second radiator 402.
It should be noted that the antenna feed point 403 is disposed at the middle position of the second radiator 402, which means that the antenna feed point 403 is not only located at the midpoint of the bottom edge of the second radiator 402, but also slightly left or right, for example, located in a predetermined range from the left to the right of the midpoint of the bottom edge, where the predetermined range is 3 mm.
Research shows that the distance between the antenna feed point and the ground feed part has great influence on the receiving and transmitting of signals by the antenna, and the distance can not only influence the process of receiving and transmitting the signals by the antenna, but also influence the quality of the signals received and transmitted by the antenna. And through research and test, if the distance between the antenna feed point and the ground feeding part is ensured to be between 55mm and 70mm, the antenna can transmit and receive signals to achieve a better effect, namely when the distance between the antenna feed point and the ground feeding part is within the range of 55mm-70mm, the antenna can better receive and transmit signals, and meanwhile, the quality of the signals received and transmitted by the antenna is better. Of course, the distance between the antenna feed and the ground feed needs to be determined according to the size of the mobile phone and the clearance.
In the prior art, because the metal shell of the USB interface has a great influence on the antenna transceiving signals, even if the distance between the antenna feeding point and the ground feeding part is adjusted within a proper range, the antenna transceiving signals cannot achieve a good effect.
The antenna provided by this embodiment eliminates the influence of the metal shell of the USB interface on the antenna transmitting and receiving signals due to the integrated design of the first radiator and the USB interface. Therefore, the position of the antenna feed point is further adjusted, so that the distance between the antenna feed point and the ground feed part is in a proper range, the antenna can better receive and transmit signals, and meanwhile, the signal quality of receiving and transmitting signals by the antenna is improved.
In this embodiment, the antenna feed point is disposed at the middle position of the bottom edge of the second radiator, so that the distance between the antenna feed point and the ground feeding portion is within a suitable range.
On the basis that the USB interface and the first radiator are integrally designed, namely after the influence of the USB metal shell on the antenna receiving and transmitting signals is eliminated, the distance between the antenna feed point and the ground feed part is further adjusted to the optimal range, so that the antenna receiving and transmitting signals can achieve a better effect.
EXAMPLE III
On the basis of the first embodiment and the second embodiment, the antenna feed point can be further connected with a metal shell of the USB interface. Fig. 5 is a schematic structural diagram of another embodiment of the antenna provided by the present invention.
The metal shell of the USB interface 501 is connected to the middle position of the bottom side of the second radiator 502 through metal.
The antenna feed point 503 is disposed on the metal shell of the USB interface 501.
As shown in fig. 5, the metal shell of the USB interface 501 is connected to the middle position of the bottom edge of the second radiator 502, that is, the USB interface 501 is disposed at the middle position of the bottom edge of the metal frame.
As can be seen from the description of the second embodiment, since the distance between the antenna feed point and the ground feeding portion also has a great influence on the transmission and reception of signals by the antenna, and in order to make the transmission and reception of signals by the antenna more effective, the distance between the antenna feed point and the ground feeding portion needs to be adjusted to be within an optimal range, which is found by research, to be between 55mm and 70 mm. In order to achieve a better signal receiving and transmitting effect of the antenna, the antenna feed point should be arranged in the middle, that is, the antenna feed point should be arranged at the middle position of the bottom edge, the position of the antenna feed point can be adjusted finely as required, and the distance between the antenna feed point and the ground feed part can be ensured to be within an optimal range.
However, in many cases, the USB interface is required to be disposed at the middle position of the bottom edge of the metal frame, and in order to achieve better effect of transmitting and receiving signals by the antenna, the antenna feed point is also required to be disposed at the middle position of the device. Based on the above requirement, the antenna feed point 503 may be further disposed on the metal shell of the USB interface 501.
Because the first radiator and the USB interface are integrally designed, the antenna feed point 503 can be directly arranged on the metal shell of the USB interface, so that the connection relation between the antenna feed point and the radiator is ensured, and meanwhile, the distance between the antenna feed point and the ground feed part is in an optimal range at the middle position of the device, so that the antenna can receive and send signals to achieve a better effect.
This embodiment, through being connected antenna feeder and the metal casing of USB interface, both satisfied with the USB interface and set up the design demand in metal frame base intermediate position, simultaneously, also can make antenna feeder and feed the distance between the ground portion and be in optimum range, reach better antenna transceiver's effect.
Example four
In order to ensure the impedance matching of the antenna and prevent a large amount of signal reflection, the antenna provided by the invention further comprises: a matching network 604.
Fig. 6 is a schematic structural diagram of another embodiment according to the present invention.
A matching network 604 is connected between the antenna feed 603 and the metal housing of the USB interface 601.
A matching network 604 for providing a characteristic impedance of the antenna.
Because the mobile phone antenna is a standing wave antenna, if the impedance of the antenna is not matched, a large amount of signals are reflected, the radiation efficiency of the antenna is reduced, and due to the influence of reflection, the gain of the antenna in a wide frequency band is jittered, so that the power capacity is reduced.
Therefore, the matching network 604 is further added in the present embodiment to implement matching of antenna impedance, avoid the phenomenon of a large amount of signal reflection, improve the radiation efficiency of the antenna, and prevent the gain of the antenna in a wide frequency band from jittering.
The matching network includes at least one of: active devices and passive devices.
When the matching network comprises the active device, the active tunable device comprises an active tunable switch or an active tunable capacitor.
The matching network can select an active device and a passive device according to the requirement, or select the active device and the passive device to be combined to form the matching network.
When the matching network includes an active device, the active device may be an active tunable device, specifically, an active tunable switch, or an active tunable capacitor.
Based on the antenna provided by the above embodiment, an embodiment of the present invention further provides a wireless communication device, which includes the antenna provided by the above embodiment, and further includes a touch screen and a battery.
The wireless communication device carries out integrated design on a first radiator of the antenna and a USB on the wireless communication device, the second radiator is designed into a closed-loop metal frame without a seam, and a USB interface is connected with the second radiator metal. Because this wireless communication equipment has carried out the integrated design to the first irradiator of antenna and the USB on the wireless communication equipment, has eliminated the influence of original USB interface to antenna receiving and dispatching signal to on this basis, realized the design of metal frame closed loop, reduced manufacturing cost greatly.
In the embodiment of the present application, the type of the wireless communication device is not specifically limited, and for example, the wireless communication device may be a mobile terminal such as a mobile phone or a tablet computer.
