Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The inventor finds that in the related art, the antenna design mode of expanding the bandwidth by arranging a plurality of antenna branches or adding a plurality of antenna switches still has difficulty in meeting the 5G communication bandwidth requirement of the medium-high frequency band after the antenna structure is installed in a smaller installation space. Therefore, the embodiment of the application provides a 5G antenna structure, which can solve the problem and improve the use experience of a user in using a 5G product.
As shown in fig. 1, the 5G antenna structure 100,5G antenna structure 100 provided in one embodiment of the present application includes a radio frequency circuit 110 and a radiator 120.
The radio frequency circuit 110 is configured to generate a radio frequency signal, and a feeding point 111 is disposed on the radio frequency circuit 110. The radiator 120 includes a main radiator 121 and a sub radiator 122 which are connected to the feeding point 111 in a feeding manner and transmit and receive radio frequency signals, so that the main radiator 121 and the sub radiator 122 can be connected to the radio frequency circuit 110 through the feeding point 111 to complete signal transmission.
The main radiator 121 may be used as the main radiator 120 of the 5G antenna structure 100 for receiving and transmitting signals, and the auxiliary radiator 122 is used for assisting the main radiator 121 to adjust the frequency shift to expand the antenna bandwidth. For example, in the case where the main radiator 121 is limited by conditions such as an installation position and an installation space, the bandwidth of the 5G antenna structure 100 may be widened by changing the shape or the installation position of the sub-radiator 122 to assist the main radiator 121 in adjusting the frequency shift, so as to flexibly design the antenna structure and improve the applicability of the 5G antenna structure 100.
In this embodiment, the main radiator 121 may be used to be mounted on a surface layer of a housing of the electronic device 200, so that the main radiator 121 may obtain a good antenna environment. The main radiator 121 is provided with a break point 1211, one end of the main radiator 121 far away from the break point 1211 is grounded, and a Loop antenna (Loop antenna) Loop is formed from the radio frequency circuit 110 to the feed point 111 and then from the feed point 111 to the main radiator 121, the auxiliary radiator 122 and the main radiator 121 respectively. The housing of the electronic device 200 for mounting the main radiator 121 may be a metal housing, for example, when the main radiator 121 is mounted on the electronic device as a part of a metal middle frame, an end of the main radiator 121 far from the break point 1211 is insulated from the metal middle frame and grounded, and the break point 1211 on the main radiator 121 is used for disconnecting the main radiator 121 from an end of the metal middle frame, so as to form a Loop antenna Loop, and due to low sensitivity of the Loop antenna, the influence of the metal middle frame (the part other than the main radiator 121) on the antenna can be reduced.
The main radiator 121 is provided with a switch loading point 1212, the switch loading point 1212 is electrically connected with an antenna switch 130 for coordinating the frequency bands of the main radiator 121 and the auxiliary radiator 122, a connection point 1213 is arranged on the main radiator 121 between the switch loading point 1212 and the breakpoint 1211 and close to a first preset distance of the breakpoint 1211, the connection point 1213 is electrically connected with the feed point 111 and the auxiliary radiator 122, the antenna switch 130 and the auxiliary radiator 122 are both arranged between the radio frequency circuit 110 and the main radiator 121 and are positioned on one side far from the breakpoint 1211, and the antenna switch 130 is arranged at a second preset distance far from the feed point 111.
According to the 5G antenna structure 100 provided by the embodiment of the application, the distance between the connection point 1213 used for being connected with the feeding point 111 and the breakpoint 1211 on the main radiator 121 and the distance between the control antenna switch 130 and the feeding point 111 are respectively within the corresponding preset distance range, the main radiator 121 is arranged on the surface layer of the shell of the electronic device, the auxiliary radiator 122 is arranged between the main radiator 121 and the radio frequency circuit 110, and the positions of all elements of the 5G antenna structure 100 are reasonably distributed, so that the 5G antenna structure 100 is flexible and simple in coordination mode, excessive matching is not required to be added, and the 5G communication requirement can be met only by a small antenna clear space.
The radio frequency circuit 110 is installed in the casing of the electronic device, the main radiator 121 is installed on the surface layer of the casing of the electronic device, preferably, the main radiator 121 is installed on the surface layer of the middle frame of the electronic device, the space between the radio frequency circuit 110 and the middle frame of the electronic device forms an installation space for installing the 5G antenna structure 100 in the electronic device, the auxiliary radiator 122 and the antenna switch 130 are installed in the installation space, and only the elements related to the 5G antenna structure 100 can be installed in the installation space so as to prevent other elements from interfering the signal receiving and transmitting of the auxiliary radiator 122.
The end of the main radiator 121 having the break point 1211 may be disposed adjacent to the communication interface 160 of the electronic device, and the communication interface 160 may be insulated from the break point 1211, such that the end of the main radiator 121 is spaced apart from the frame of the electronic device by disposing the communication interface 160, and an insulating decoration (not shown) may be disposed at the periphery of the communication interface to modify the break point 1211 to beautify the appearance of the electronic device.
A substrate may be disposed in the housing of the electronic device, and the antenna structures such as the radio frequency circuit 110, the auxiliary radiator 122, and the antenna switch 130 mounted in the electronic device may be mounted on the substrate, so that the mounting positions of the elements of the 5G antenna structure 100 may be conveniently controlled by the substrate. The substrate may be made of a hard material to firmly mount the mounting positions of the components of the 5G antenna structure 100 in the electronic device, so as to maintain the mounting stability of the 5G antenna structure 100.
The distance between the connection point 1213 and the disconnection point 1211 on the main radiator 121 for connection with the feeding point 111 is a first preset distance, which in some exemplary embodiments may range from 1.0 mm to 2.0 mm, for example, the first preset distance may be 1.0 mm, 1.5 mm, or 2.0 mm, within which the feeding requirements of the main radiator 121 and the sub-radiator 122 for connection with the feeding point 111 may be satisfied. When the first preset distance is less than 1.0 mm, the feeding point 111 is too close to the break point 1211, which may interfere with signal transmission between the main radiator 121 and the sub-radiator 122 and the feeding point 111 if the break point 1211 is disposed adjacent to other electronic components, and the too close distance also does not facilitate installation of the components in the 5G antenna structure 100. When the first preset distance is greater than 2 mm, the feeding point 111 is too far from the break point 1211, so that the end of the main radiator 121 with the break point 1211 occupies too much space, which is inconvenient for the miniaturization design of the entire 5G antenna structure 100.
The antenna switch 130 is disposed at a second preset distance away from the feeding point 111, in some exemplary embodiments, the second preset distance ranges from 5.0 mm to 6.0 mm, for example, the second preset distance may be 5.0 mm, 5.5 mm or 6.0 mm, where the interference of the feeding point 111 on the tuning antenna frequency band of the antenna switch 130 caused by too close distance between the feeding point 111 and the antenna switch 130 is prevented, and at the same time, the too large distance between the antenna switch 130 and the feeding point 111 does not cause the increase of the total antenna structure to occupy too much installation space.
In some exemplary embodiments, the antenna switch 130 may be a single pole multi-throw switch, where the antenna switch 130 is provided with one moving end 131, N fixed ends 132, and one signal transmission end 133, N is an integer greater than 1, the switch loading point 1212 is connected to the signal transmission end 133, the signal transmission end 133 is connected to the moving end 131, the N fixed ends 132 are grounded, and the moving end 131 is controlled to be connected to one of the N fixed ends 132 to coordinate the frequency bands of the main radiator 121 and the sub radiator 122. The antenna switch 130 is further provided with a control end, the control end is connected to a controller 140, the controller 140 is configured to generate a switch control signal, send the switch control signal to the antenna switch 130, and the switch control signal is configured to control the movable end 131 of the antenna switch 130 and one of the N fixed ends 132 to be connected to each other, so as to select one of the N fixed ends 132 to be connected to the main radiator 121 and the auxiliary radiator 122 through the switch loading point 1212.
The controller 140 may be implemented in at least one hardware form of digital signal processing (digital signal processing, DSP), field-programmable gate array (field-programmable gatearray, FPGA), programmable logic array (programmable logic Array, PLA). The switch control signal may be a digital pulse signal, and the controller 140 controls the moving terminal 131 of the antenna switch 130 to be connected to the different stationary terminals 132 using the encoding of the digital pulse signal. For example: the antenna switch 130 is provided with four stationary ends 132: the fixed end I, the fixed end II, the fixed end III and the fixed end IV; when the code of the digital pulse signal is 1000, the antenna switch 130 controls the movable end 131 to be connected with the fixed end I; when the code of the digital pulse signal is 0100, the antenna switch 130 controls the movable end 131 to be connected with the second fixed end; when the code of the digital pulse signal is 0010, the antenna switch 130 controls the movable end 131 to be connected with the stationary end III; when the digital pulse signal is encoded as 0001, the antenna switch 130 controls the movable terminal 131 to be connected with the stationary terminal four.

The movable end 131 of the single-pole four-throw antenna switch 130 can be controlled to be connected with one of the four fixed ends 132 in real time, so that the antenna matching network connection of the fixed end 132, which is most matched with the 5G NR main concentrated high frequency band and the 5G NR diversity n77/78/79 frequency band, in the antenna switch 130 can be selected, and meanwhile, the frequency shift is coordinated through the auxiliary radiator 122, so that the antenna frequency band can be flexibly tuned.
