Detailed Description
The following describes the mobile phone antenna and the mobile phone of the present invention in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention. Further, the structures illustrated in the drawings are often part of actual structures. In particular, the drawings may have different emphasis points and may sometimes be scaled differently.
As shown in fig. 1, the basic structure of the conventional mobile phone antenna is a LOOP-type routing structure, in which low frequency, intermediate frequency and high frequency in an antenna signal need to be sent from a feeding point and finally return to a place through all areas of LOOP-type LOOP routing. In order to enable the high-frequency parasitic element to couple out the optimal medium-high frequency signal, the antenna structure is adjusted to adjust the ultrahigh frequency and the partial medium frequency, but the efficiency of the partial low frequency is sacrificed, so that the low-frequency efficiency is low.
Based on this, the present embodiment provides a mobile phone antenna, as shown in fig. 2, the mobile phone antenna includes a high-frequency parasitic element 10 and a low-frequency main element 20 coupled to each other; the low frequency main body unit 20 has a USB hole 21, the low frequency main body unit 20 is provided with a feeding point 22 at a side of the USB hole 21 close to the high frequency parasitic element 10, and a place 23 at a side of the USB hole 21 far from the high frequency parasitic element 10, and the feeding point 22 and the place 23 are communicated along the periphery of the USB hole 21.
In the mobile phone antenna provided in this embodiment, the feeding point 22 and the location 23 are communicated along the periphery of the USB hole 21, so that the medium-high frequency signal of the antenna can be directly returned to the location 23 through the routing directly communicated with the periphery of the USB hole 21 after being emitted from the feeding point 22 and coupled with the high-frequency parasitic unit 10, and does not need to go around all antenna routing returning locations 23 from the feeding point 22; meanwhile, other wires of the low-frequency main body unit 20 are basically low-frequency signal wires, so that low-frequency signals and medium-high frequency signals in the antenna can be received and transmitted through different wires, the efficiency of low-frequency signals of the antenna is improved on the basis that the efficiency of medium-high frequency signals is not affected, and the problem of low-frequency efficiency of the conventional mobile phone antenna is solved.
Further, in the mobile phone antenna provided by this embodiment, the distance between the feeding point 22 and the location 23 is 15-17 mm. The distance between the feeding point 22 and the location 23 depends on the antenna environment and the antenna loop design, and the distance of 15-17 mm is preferred in consideration of the antenna length and the antenna performance. Of course, in other embodiments, there may be differences in distance depending on the antenna trace design.
Still further, in the mobile phone antenna provided in this embodiment, the high-frequency parasitic element 10 includes a parasitic point 11, and a distance between the parasitic point 11 and the feeding point 22 is 16-18 mm. The distance between the parasitic point 11 and the feeding point 22 depends on the distribution of each band of the antenna, and since the high-frequency parasitic element 10 in this embodiment only assists in high frequency, the parasitic point 11 should be close to the high-frequency distribution region of the antenna, i.e. close to the feeding point 22. Meanwhile, since the length required for forming the high frequency is about 16 to 18mm, it is preferable to select a distance of 16 to 18mm according to the design requirements and subsequent adjustment of the antenna. Of course, in other embodiments, there may be a difference in distance depending on the antenna trace design.
Further, in the antenna of the mobile phone provided in this embodiment, the location 23 is connected in series with a switch (not shown in the figure), and the switch is used for switching the low frequency of the antenna. The switch is only required to satisfy the low-frequency switching function of the mobile phone antenna, and may be selected differently in different embodiments, for example, it may be a single-pole four-throw switch or a double-pole double-throw switch conventionally selected by those skilled in the art. The selection of switches and the design of circuit connections are well known to those skilled in the art and will not be described in detail herein.
In order to achieve the bandwidth, frequency range, peak amplitude, and even coupling effect of the mobile phone antenna, a control slot is usually disposed on the mobile phone antenna. In the present embodiment, as shown in fig. 2, a control slot 24 is disposed on a side of the low frequency main unit 20 near the high frequency parasitic unit 10 at the USB hole 21, and the control slot 24 is used to control the antenna frequency range. In practical application, the length, position and shape of the control slot can be adjusted according to different antenna function requirements to meet the requirements. Even more, in some embodiments, multiple control slots may be provided to meet antenna functional requirements for different frequency ranges.
In this embodiment, the mobile phone antenna is preferably an FPC antenna. FPC (Flexible Printed Circuit) is a Flexible Printed Circuit board which is made of polyimide or polyester film as a base material and has high reliability and excellent properties. The FPC has the characteristics of high wiring density, light weight, thin thickness and good bending property, so that the mobile phone antenna can be well attached to a mobile phone assembly area by using the FPC antenna, and the internal space of the mobile phone can be saved.
The embodiment also provides a mobile phone, which comprises the mobile phone antenna as described above.
Although the mobile phone provided by the embodiment includes the mobile phone antenna provided by the above embodiment, the efficiency of the low-frequency signal of the antenna can be improved on the basis of not affecting the efficiency of the medium-high frequency signal, because the USB socket 32 is made of metal, and there is a circuit connection between the USB socket 32 and the USB motherboard 31, when the feeding point 22 and the location 23 are communicated along the periphery of the USB hole 21, the efficiency of the antenna is inevitably affected by the too close distance between the antenna and the USB socket 32 or the USB motherboard 31, and the most seriously affected part is the low frequency of the antenna.
In order to ensure that the mobile phone antenna is not coupled with the USB socket and the USB motherboard to affect the antenna efficiency, at least a distance of 0.7mm is usually ensured between the mobile phone antenna and the USB socket and the USB motherboard.
At present, the mobile phone is thinner and thinner, so that the space in the mobile phone is smaller and smaller, and the distance between the mobile phone antenna and the USB socket 32 and the USB mainboard 31 is limited to be impossible to be larger. When the feeding point 22 and the ground 23 of the mobile phone antenna are connected along one side of the USB hole 21 close to the USB motherboard 31 (i.e. below the USB hole in fig. 2), after the mobile phone antenna is assembled with the USB socket, the distance between the mobile phone antenna and the USB socket and the USB motherboard is usually reduced to about 0.5mm, which may cause the mobile phone antenna to be coupled with the USB socket and the USB motherboard, thereby absorbing the antenna efficiency and causing poor performance of low frequency.
In order to further solve the above problem, in this embodiment, as shown in fig. 3 and fig. 4, the mobile phone further includes a USB motherboard 31 and a USB socket 32 electrically connected and fixed on the USB motherboard 31, wherein the USB socket 32 is correspondingly assembled with the USB hole 21 of the mobile phone antenna; the feeding point 22 and the ground point 23 communicate with each other along a side of the USB port 21 away from the USB board 31.
The antenna structure of the mobile phone shown in fig. 3 is different from the antenna structure of the mobile phone shown in fig. 2 in that the feeding point 22 and the ground point 23 are communicated along a side of the USB hole 21 away from the USB motherboard 31 (i.e., above the USB hole in fig. 3). Because the wiring connecting the feeding point 22 and the place 23 is along the upper part of the USB interface 32, the distance between the antenna wiring and the connecting surface of the USB interface 32 and the USB mainboard 31 is far, the height problem of the USB interface 32 and the USB mainboard 31 from the antenna surface does not exist, the efficiency of coupling between the mobile phone antenna and the USB interface and the USB mainboard can be effectively reduced, and further the low-frequency efficiency of the mobile phone antenna can be effectively improved.
The inventor has proved through a large number of experiments that the minimum distance between the feed point 22 and the point 23 and the side of the USB socket 32 far away from the USB motherboard 31 (i.e., above the USB hole in fig. 3) of the communication trace is 0.3mm, while ensuring low-frequency efficiency. The space occupied by the mobile phone antenna in the mobile phone is greatly saved, and the space in the mobile phone is further reduced.
In summary, the present embodiment provides a mobile phone antenna and a mobile phone, wherein the mobile phone antenna includes a high-frequency parasitic unit and a low-frequency main unit coupled to each other; the low-frequency main body unit is provided with a USB hole, a feeding point is arranged on one side, close to the high-frequency parasitic unit, of the USB hole, a place is arranged on one side, far away from the high-frequency parasitic unit, of the USB hole, and the feeding point is communicated with the place along the periphery of the USB hole. The feeding point is communicated with the place along the periphery of the USB hole, so that the medium-high frequency signal of the antenna can be directly returned to the place through the routing which is directly communicated with the periphery of the USB hole after being emitted from the feeding point and coupled with the high-frequency parasitic unit, and the antenna does not need to be wound from the feeding point to return to the place through all antenna routing; meanwhile, other wires of the low-frequency main body unit are low-frequency signal wires basically, so that low-frequency signals and medium-high frequency signals in the antenna can be received and transmitted through different wires, the efficiency of low-frequency signals of the antenna is improved on the basis that the efficiency of medium-high frequency signals is not influenced, and the problem of low-frequency efficiency of the conventional mobile phone antenna is solved.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
