Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the embodiments of the present invention is given with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Embodiment one:
in order to improve the space utilization rate of the terminal, more frequency band antennas are arranged in a limited space, please refer to fig. 1, the present embodiment provides a terminal device, which includes at least two metal structural members separated from each other, including a first structural member 11 and a second structural member 12 disposed adjacently, and a first gap is disposed between adjacent ends of the first structural member 11 and the second structural member 12; wherein:
the first structural member 11 is provided with a first antenna 111 and a first grounding wire 112, and the first grounding wire 112 is arranged far away from the second structural member 12;
the second structural member 12 is provided with a second antenna 121 and a second grounding wire 122, and the second grounding wire 122 is arranged far away from the first structural member 11;
the first antenna 111 is directly grounded through the first ground line 112 to form a first band antenna; the second antenna 121 is directly grounded through a second grounding wire 122 to form a second frequency band antenna;
at least one of the first antenna 111 and the second antenna 121 is coupled to an antenna on another metal structural member through a first slot, and is grounded through a ground wire on the metal structural member, thereby forming a coupled antenna.
Each antenna arranged on the terminal device in the embodiment is used for realizing wireless communication with different requirements. For example, each antenna in the embodiment may include a WIFI corresponding frequency band corresponding to a WIFI connection of a wireless network communication technology, which may specifically include 2.4G WIFI, a frequency band range of (2.4 GHz-2.5 GHz) and 5G WIFI, and a frequency band range of (5.2-5.8 GHz); the corresponding frequency band of GPS (Global Positioning System ) can also be (1.575 GHz); or 5GNR (5G New Radio) n78, the frequency band range is (3.3 GHz-3.6 GHz); and LTE (Long Term Evolution, long term evolution of general mobile communication technology), the frequency ranges are (1805-2690 MHz), and are LTE low-medium-high frequency diversity MIMO (multiple-in multiple-out), the frequency ranges are low-frequency diversity MIMO (729-960 MHz) and medium-high frequency diversity MIMO (1805-2690 MHz), respectively. The above only lists the frequency range corresponding to some optional wireless communication technologies on the terminal, and the antenna of the terminal may be set to include, but not limited to, the frequency range corresponding to each wireless communication means according to the design and application requirements of the terminal, which is not limited in this embodiment.
In this embodiment, in order to implement multiplexing of radiators of multiple antennas, at least two mutually separated metal structural members are disposed on the terminal device; the at least two metal structural members are respectively provided with corresponding antennas and grounding wires, namely a first antenna 111 and a first grounding wire 112 which are arranged on the first structural member 11, and a second antenna 121 and a second grounding wire 122 which are arranged on the second structural member 12; wherein, both grounding wires are far away from the other metal structural part.
For the first structural member 11, the first antenna 111 disposed thereon may be directly grounded through the first ground line 112, thereby forming a first frequency band antenna; the first frequency band antenna can be correspondingly provided with a corresponding frequency band to meet the wireless communication requirement of the corresponding frequency band, and the frequency band comprises but is not limited to the frequency band range listed in the embodiment.
For the second structural member 12, the second antenna 121 disposed thereon may be directly grounded through the second ground wire 122, so as to form a second frequency band antenna; similar to the first band antenna, the second band antenna may also be correspondingly configured with a corresponding band, so as to realize wireless communication requirements of the corresponding band, where the band also includes, but is not limited to, the band ranges listed in the above-mentioned embodiment. In general, the first band antenna and the second band antenna may have corresponding frequency ranges that are not overlapped with each other.
In order to realize antenna radiator multiplexing, the coupling of antenna signals can be realized by utilizing a first gap between the first structural member 11 and the second structural member 12; wherein, the antenna on at least one of the first structural member 11 and the second structural member 12 is coupled with the antenna on the other through the first slot, and then is grounded through the grounding wire on the other, thereby forming a coupled antenna. Compared with a first frequency band antenna and a second frequency band antenna which are formed by the metal structural members of the coupling antenna, the coupling antenna is coupled by the other metal structural member, namely multiplexing of antenna radiators is realized, coverage of more frequency band antennas can be realized under the same radiator architecture, and the space utilization rate of the terminal is improved.
Specifically, the first antenna 111 and the second antenna 121 may each be coupled by each other to form a coupled antenna; that is, at least one of the first antenna and the second antenna is coupled to the antenna on the other metal structure through the first slot, and is grounded through a ground wire on the metal structure to form a coupled antenna, which may specifically include: the first antenna 111 may be coupled to the second antenna 121 through a first slot and grounded through the second ground line 122 to form a third band antenna;
the second antenna 121 may be coupled to the first antenna 111 through the first slot, and grounded through the first ground line 112, so as to form a fourth band antenna. The third frequency band antenna and the fourth frequency band antenna are both based on the first slot and are coupled with the other antenna to form a coupled antenna, namely, the space arrangement of the two antennas is utilized, and the antennas of four frequency bands can be realized, so that the coverage rate of the antennas is further improved, namely, the space utilization rate of the terminal is improved.
In order to reduce or even eliminate signal interference between antennas while improving the space utilization of the terminal and avoid degradation of throughput rate caused by isolation and other reasons of adjacent antennas, in some embodiments, a first filter 113 corresponding to a fourth frequency band antenna is loaded on path matching of the first antenna 111; the frequency band corresponding to the fourth frequency band antenna is not overlapped with the frequency bands corresponding to the first frequency band antenna and the third frequency band antenna. That is, in order to make the fourth-band antenna not affected by the first antenna 111, the first filter 113 may be loaded on the path matching of the first antenna 111, where the first filter 113 is set corresponding to the fourth-band antenna, and may filter out the frequency band corresponding to the fourth-band antenna, so that the fourth-band antenna does not pass through the feed of the first antenna 111 while using the radiator of the first antenna 111; and because the fourth frequency band antenna is not overlapped with the frequency bands corresponding to the first frequency band antenna and the third frequency band antenna, the first filter 113 will not affect the first frequency band antenna and the third frequency band antenna corresponding to the first antenna 111. Specifically, if the band corresponding to the fourth band antenna is 2.4G WIFI, the first filter 113 may correspondingly include a band reject filter corresponding to the 2.4G WIFI. The band-stop filter refers to a filter which can pass most frequency components, but attenuates certain frequency components to an extremely low level, and the band-stop filter corresponding to 2.4G WIFI attenuates the 2.4G WIFI frequency band to an extremely low level.
Similarly, on the path matching of the second antenna 121, a second filter 123 corresponding to the third band antenna may be loaded; the frequency band corresponding to the third frequency band antenna is not overlapped with the frequency bands corresponding to the second frequency band antenna and the fourth frequency band antenna. In order to make the third frequency band antenna not affected by the second antenna 121, a second filter 123 may be loaded on the path matching of the second antenna 121, where the second filter 123 is set corresponding to the third frequency band antenna, and may filter out the frequency band corresponding to the third frequency band antenna, so that the third frequency band antenna does not pass through the feed of the second antenna 121 while using the radiator of the second antenna 121; and the third frequency band antenna is not overlapped with the frequency bands corresponding to the second frequency band antenna and the fourth frequency band antenna, so that the second filter 123 does not affect the second frequency band antenna and the fourth frequency band antenna corresponding to the second antenna 121. Specifically, if the frequency band corresponding to the third frequency band antenna is a global positioning system GPS; the second filter 123 may then comprise in particular a GPS-corresponding band reject filter. The band-stop filter set based on 2.4G WIFI or GPS is merely an example in this embodiment, and those skilled in the art may set a corresponding band-stop filter, a low-pass filter, a high-pass filter, etc. according to specific requirements, and this embodiment is not limited thereto.
The metal structural members in this embodiment may be disposed on a metal frame/middle frame of the terminal, where the metal structural members of each segment are separated by an insulating material.
The terminal equipment provided by the embodiment comprises at least two mutually separated metal structural members, wherein the terminal equipment comprises a first structural member 11 and a second structural member 12 which are adjacently arranged, and a first gap is arranged between adjacent end parts of the first structural member 11 and the second structural member 12; wherein: the first structural member 11 is provided with a first antenna 111 and a first grounding wire 112, and the first grounding wire 112 is arranged far away from the second structural member 12; the second structural member 12 is provided with a second antenna 121 and a second grounding wire 122, and the second grounding wire 122 is arranged far away from the first structural member 11; the first antenna 111 is directly grounded through the first ground line 112 to form a first band antenna; the second antenna 121 is directly grounded through a second grounding wire 122 to form a second frequency band antenna; at least one antenna among the first antenna 111 and the second antenna 121 is coupled with the antenna on the other metal structural member through a first slot and is grounded through the grounding wire on the metal structural member to form a coupled antenna, and in certain implementation processes, the coupled antenna can be formed by coupling between the two metal structural members and the adjacent antennas, so that the number of actual antennas is effectively increased, each antenna can meet the requirement of more frequency bands, the communication performance of the terminal is improved, the space of the terminal is saved, and the size of the terminal can be reduced.
Embodiment two:
the embodiment further provides a terminal device, please refer to fig. 2, which includes at least three metal structural members separated from each other, and a third structural member 13 in addition to the first structural member 11 and the second structural member 12 that are adjacently disposed, where the third structural member 13 is adjacently disposed with the second structural member 12, a first gap is disposed between adjacent ends of the first structural member 11 and the second structural member 12, and a second gap is disposed between adjacent ends of the second structural member 12 and the third structural member 13;
the second structural member 12 is further provided with a third antenna 124, and the third antenna 124 is disposed between the second ground wire 122 and the second slot; the third structural member 13 is provided with a fourth antenna 131 and a third ground wire 132, and the third ground wire 132 is disposed away from the second slot.
For realizing more frequency band antennas, in this embodiment, the terminal device includes three metal structural members separated from each other, and compared with the above embodiment, a third structural member 13 is added, where the third structural member 13 is disposed adjacent to the second structural member 12; in this structure, a third antenna 124 may be provided on the second structural member 12 in addition to the already provided second antenna 121, and the third antenna 124 is provided at a position between the second ground line 122 and the second slot; the third structural member 13 is also provided with a fourth antenna 131 and a third ground wire 132, and the third ground wire 132 is far away from the second slot.
After the third antenna 124 is disposed on the second antenna 121, the third antenna 124 may be directly grounded through the second ground line 122, so as to form a fifth frequency band antenna; the fourth antenna 131 may be directly grounded through the third ground wire 132 to form a sixth frequency band antenna; the fifth frequency band antenna and the sixth frequency band antenna are antennas which are directly formed on the corresponding metal structural members; in addition, the fourth antenna 131 may be coupled to the third antenna 124 through the second slot and grounded through the second ground line 122 to form a seventh band antenna. And the seventh frequency band antenna is similar to the third frequency band antenna and the fourth frequency band antenna, belongs to a coupling antenna for coupling with the adjacent antennas, is equivalent to a radiator multiplexing other antennas, and improves the space utilization rate on the terminal.
In order to reduce or even eliminate signal interference between antennas while improving the space utilization of the terminal and avoid degradation of throughput rate caused by isolation or the like of adjacent antennas, in some embodiments, a third filter 125 corresponding to a seventh-band antenna is loaded on path matching of a third antenna 124; the frequency band corresponding to the seventh frequency band antenna is not overlapped with the fifth frequency band antenna. That is, in order to make the seventh-band antenna not affected by the third antenna 124, the third filter 125 may be loaded on the path matching of the third antenna 124, where the third filter 125 is disposed corresponding to the seventh-band antenna, and the band corresponding to the seventh-band antenna may be filtered, so that the seventh-band antenna does not pass through the feed of the third antenna 124 while using the radiator of the third antenna 124; since the frequency bands corresponding to the seventh-band antenna and the fifth-band antenna do not overlap, the third filter 125 does not affect the fifth-band antenna corresponding to the third antenna 124. Specifically, if the frequency band corresponding to the seventh frequency band antenna is low frequency diversity MIMO, the third filter 125 may include a high pass filter with a cut-off frequency equal to or higher than the maximum frequency of the low frequency diversity MIMO, for example, when the frequency band corresponding to the seventh frequency band antenna is LTE low frequency diversity MIMO (729-960 MHz), the cut-off frequency of the high pass filter may be 1GHz. That is, in this embodiment, through the three-section metal structural member, the implementation of the antenna including the seven frequency bands from the first frequency band antenna to the seventh frequency band antenna can be realized, so that the space utilization rate of the terminal is greatly improved, and the requirement of the antenna with multiple frequency bands can be met on the premise of reducing the size of the terminal.

In summary, according to the embodiment, through the three metal structural members, the antenna function of seven frequency bands is realized, and the space utilization rate of the terminal is improved.
