The present invention relates to the technical field of communication, and more specifically, to a mobile terminable.
With the continuous development of mobile terminal equipment such as mobile phones and tablet computers, there are higher and higher requirements for terminal signals, speech quality and appearance. Mobile terminals with an all-metal back cover enjoy the tremendous popularity among consumers by virtue of the metallic texture, ruggedness and wear-resistance.
However, the all-metal back cover shields the signals of the antenna module in the mobile terminal equipment. In some mobile terminal equipment of related technologies, a slot is made in a part of metal back cover which is opposite to the antenna module to prevent the metal back cover from interfering antenna signals, which sacrifices the consistency of the housing appearance and affects the overall appearance of the mobile terminal equipment.
Therefore, it is necessary to provide an improved mobile terminal to overcome above disadvantage.
Many aspects of the embodiment can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The present invention will hereinafter be described in detail with reference to an exemplary embodiment. To make the technical problems to be solved, technical solutions and beneficial effects of present disclosure more apparent, the present disclosure is described in further detail together with the figures and the embodiment. It should be understood the specific embodiments described hereby is only to explain this disclosure, not intended to limit this disclosure.
With reference to
The housing 1 further comprises a housing 11 and a metal frame 12 which together forms an accommodation space. The mainboard 2 is provided with a ground point through which an antenna system is grounded, and the metal frame 12 serves as the radiator of the antenna system.
Furthermore, the mobile terminal 100 is also provided with a subsidiary antenna system 4 which comprises a decomposing antenna 41 and a functional antenna 42. The decomposing antenna 41 and the functional antenna 42 are also connected with the mainboard 2 and grounded through the mainboard 2, similarly, the decomposing antenna 41 and the functional antenna 42 also feed power to the metal frame 12 and radiate through the same. The functional antenna may be a WIFI antenna or a GPS antenna.
The main antenna 3 is separated from the subsidiary antenna system 4 and the decomposing antenna 41 is separated from the functional antenna 42 through a matching system 33. The matching system 33 may be a device with power supply which may be a tuner or converter, or a device without power supply which may be a lumped element. Matching systems are added to the different locations of the metal frame 12. The specific locations and spacing of the matching systems may affect the length of the effective radiators of the antenna and then affect the transmitting/receiving frequency of the antennae, so the number, locations and spacing of specific matching systems are determined as appropriate.
The main antenna 3 comprises a low-frequency feeding portion 31 and a high-frequency feeding portion 32, wherein the low-frequency feeding portion 31 is separated from the high-frequency feeding portion 32 through an LC filtering and separation system. In the present invention, the antenna is a printed antenna printed on an antenna bracket. As show in
The main antenna 3 further comprises a feeding end 33 intended for connecting the main antenna 3 to the metal frame 12 in such a way that the metal frame 12 serves as the radiator of the antenna system to receive and transmit electromagnetic radiation. The feeding end 33 further comprises a low-frequency feeding end 331 and a high-frequency feeding end 332, wherein the low-frequency feeding end 331 is provided on the first extending part 311 of the low-frequency feeding portion and the high-frequency feeding end 332 is provided on the main body 321 of the high-frequency feeding portion 32. The antenna system is double-fed to the common metal frame in such a way to generate high and low frequencies and produce antenna multiplexing effects, thus it removes the need of making a slot in the back cover of the mobile terminal and makes products more attractive.
As show in
Furthermore, the main antenna 3 is located at the bottom of the accommodation space of the mobile terminal, while the decomposing antenna 41 and the functional antenna 42 are located at the top of the accommodation space. The mainboard 2 is used for bearing the antenna system and other functional devices of the mobile terminal, such as microphone and loudspeaker. A clearance zone is arranged around the main antenna where no other electronic components shall be provided, to prevent the electronic components from interfering antenna signals. The area of the clearance zone depends on the sizes of the mobile terminal and the antenna bracket, and the height of the clearance zone is at least greater than twice the height of the antenna bracket. Preferably, a clearance zone is also arranged around the decomposing antenna 41 and the functional antenna 42 respectively.
In the embodiment of the present invention, the main antenna 3 is an LTE antenna module with frequency band of 824 MHz-960 MHz or 1710 MHz-2690 MHz.
It is to be understood, however, that even though numerous characteristics and advantages of the present exemplary embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms where the appended claims are expressed.
