Description

一种改善天线辐射性能的方法及移动终端技术领域 Method for improving antenna radiation performance and mobile terminal

随着移动通信终端的快速发展，移动终端除了能满足基本的通话功能之外，人们对移动终端外型的要求越来越高，移动终端的设计也越来越赏心悦目，移动终端外壳上出现了越来越多的金属装饰件。虽然对移动终端进行了装饰，但这些金属装饰件却会影响移动终端天线的性能，尤其是低频频段的天线，性能受金属装饰件影响非常大，这无疑增加了天线调试的难度。目前，移动终端支持的频段比较多，就目前主流的宽带码分多址 With the rapid development of mobile communication terminals, in addition to meeting the basic call functions, mobile terminals are increasingly demanding the appearance of mobile terminals, and the design of mobile terminals is becoming more and more pleasing to the eye. More and more metal decorative pieces. Although the mobile terminal is decorated, these metal decorative parts will affect the performance of the mobile terminal antenna, especially in the low frequency band, the performance is greatly affected by the metal decorative parts, which undoubtedly increases the difficulty of antenna debugging. At present, mobile terminals support more frequency bands, and currently the mainstream wideband code division multiple access

( WCDMA, Wideband Code Division Multiple Access )的移动终端而言，一般会有 7个频段，包括 GSM850、 GSM900、 DCS 1800, PCS1900、 W900、 W1900、 W2100。如果在移动终端上增设金属装饰件的话，对移动终端天线的性能将不可避免地造成影响。 For mobile terminals (WCDMA, Wideband Code Division Multiple Access), there are generally seven frequency bands, including GSM850, GSM900, DCS 1800, PCS1900, W900, W1900, and W2100. If metal decorative parts are added to the mobile terminal, the performance of the mobile terminal antenna will inevitably be affected.

对于设有金属装饰件的移动终端，一般通过预留接地点来减少金属装饰件对天线的影响。但预留接地点的位置，接地点的个数等对天线调试会有非常大的影响。当预留的接地点的位置不合适或预留的接地点的数量不够时，移动终端天线的性能将会非常差。而对于当前的移动终端设计而言，为保证移动终端的耐用度及装饰需要，在移动终端机体上设置金属件几乎是不能回避的。因此，如何保证设置了金属件的移动终端的天线性能，是亟待解决的问题。发明内容 For mobile terminals with metal decorative parts, the influence of the metal decorative parts on the antenna is generally reduced by reserving the grounding point.

When the location of the reserved grounding point is not suitable or the number of reserved grounding points is insufficient, the performance of the mobile terminal antenna will be very poor. For the current mobile terminal design, in order to ensure the durability and decoration needs of the mobile terminal, it is almost impossible to circumvent the metal parts on the mobile terminal body.

以下对平面倒 F ( PIFA, Radiation of Planar Inverted-F Antenna )天线的设计原理及基本结构进行介绍。图 1为设置于移动终端中 PIFA天线原理结构示意图，如图 1所示， PIFA天线包括馈线 14和馈电面板 13 , 对于移动终端而言，馈电面板 13即是移动终端的印刷电路板（ PCB , Printed Circuit Board ), 其中，馈线 14所在的平面与移动终端中作为馈电面板 13的 PCB 平行，根据 PIFA天线的设计原理，两平行平面的距离在 6.5mm左右；馈线 14通过馈电线 11与接地线 12分别与电面板 13上的馈电源及接地点（线）连接；其中，馈线 14是具有一定宽度及设定长度的矩形片，其长度为天线所工作的无线信号的波长的四分之一，无论馈线的形状如何，馈线整体均处于同一个平面中；馈线 14、馈电线 11与接地线 12均是具有一定宽度及厚度的矩形片，其中的宽度与两平行平面的距离等有关，由于该宽度等设计属于 PIFA天线原理，这里不再赘述。上述的馈电线 11及接地线 12均垂直于馈线 14所在的平面。 The following describes the design principle and basic structure of the Planar Inverted-F Antenna (PIFA) antenna. 1 is a schematic structural diagram of a PIFA antenna disposed in a mobile terminal. As shown in FIG. 1, the PIFA antenna includes a feed line 14 and a feed panel 13. For the mobile terminal, the feed panel 13 is a printed circuit board of the mobile terminal ( PCB, Printed Circuit Board), wherein the plane of the feed line 14 is parallel to the PCB as the feed panel 13 in the mobile terminal. According to the design principle of the PIFA antenna, the distance between the two parallel planes is about 6.5 mm; the feed line 14 passes through the feed line 11 And the grounding wire 12 is respectively connected with the feeding power source and the grounding point (line) on the electric panel 13; wherein, the feeding wire 14 is a rectangular piece having a certain width and a set length, and the length thereof is the wavelength of the wireless signal working by the antenna.

Multiple feeders can be in the same plane or can be divided into different planes, but these planes are all parallel to the feed plane.

图 2为本发明移动终端机壳的金属边框作为移动终端天线馈线的示意图，如图 2所示，本示例中，移动终端的机壳（如前壳） 24上设置有装饰用的金属边框 21 , 而在该金属边框 21上，还设置有垂直于机壳所在平面的连接件（相当于图 1 中的馈电线及接地线） 22、 27、 28 , 上述连接件均设置于机壳内侧，以与移动终端天线的馈电点 23 (与移动终端 PCB板上的馈电源连接）或接地点 26连接。馈电点 23及接地点 26均设置于移动终端 PCB 板上。由于金属边框 21为环形结构，因此，在金属边框 21的底部设置有开口 25 , 以使整个金属边框 21在保持整体结构（装饰的需要，如美观）的前提下，分设为两个馈线。连接件（图 1中的接地线） 27、 28分别设置于金属边框 21开口 25的两端。 2 is a schematic diagram of a metal frame of a mobile terminal casing as a mobile terminal antenna feed line, as shown in FIG. 2, in this example, a casing (such as a front casing) 24 of the mobile terminal is provided with a decorative metal frame 21 And the metal frame 21 is further provided with a connecting member (corresponding to the feeding wire and the grounding wire in FIG. 1) 22, 27, 28 perpendicular to the plane of the casing, and the connecting members are disposed on the inner side of the casing. It is connected to a feed point 23 of the mobile terminal antenna (connected to a feed source on the mobile terminal PCB board) or a ground point 26. Feed point 23 and ground point 26 are both disposed on the mobile terminal PCB. Since the metal frame 21 has a ring structure, an opening 25 is provided at the bottom of the metal frame 21 so that the entire metal frame 21 is divided into two feeder lines while maintaining the overall structure (the need for decoration, such as aesthetics). The connecting members (the grounding wires in Fig. 1) 27, 28 are respectively disposed at both ends of the opening 25 of the metal frame 21.

具体的，将连接件（图 1中的馈电线） 22与移动终端天线的馈电点 23 连接，而连接件 27、 28均连接于移动终端天线的接地点 26连接。 Specifically, the connector (feeder in Fig. 1) 22 is connected to the feed point 23 of the mobile terminal antenna, and the connectors 27, 28 are connected to the ground point 26 of the antenna of the mobile terminal.

本发明中，移动终端中的天线支持多频段，如背景技术中提及的 GSM850、 GSM900、 DCS 1800, PCS1900、 W900、 W1900、 W2100等频段。移动终端中的天线模式为 PIFA天线。由于 PIFA天线技术是非常成熟的技术，本发明不再赘述其天线结构及实现原理。 In the present invention, the antenna in the mobile terminal supports multiple frequency bands, such as the GSM850, GSM900, DCS 1800, PCS1900, W900, W1900, W2100 and the like mentioned in the background art. The antenna mode in the mobile terminal is a PIFA antenna. Since the PIFA antenna technology is a very mature technology, the antenna structure and implementation principle are not described in the present invention.

上述在移动终端机体的金属件上所设的馈线，长度应不同于移动终端上已有天线的馈线的长度，这是考虑到移动终端上已有 PIFA天线中的谐振频率而设计的，以使该馈线产生的谐振频率不同于已有 PIFA天线所支持无线信号的频率，从而不会对移动终端天线所支持频点产生任何辐射的影响，从而保证了移动终端天线的性能。具体的， PIFA天线要求馈线长度为 1/4λ, 其中， λ为待接收信号的波长，本发明是将移动终端上的导电件设置为天线的馈线，以避免其对移动终端中原配置的天线造成辐射性能影响。而移动终端天线所支持的频率一般有 GSM850、 GSM900、 DCS1800、 PCS1900、 W900、 W1900、 W2100„ 以移动终端中已有 850M赫兹（ Hz ) PIFA天线为例，本发明的目的是使移动终端上的导电件尽可能地形成接收不同于 850M 信号的天线， 850M赫兹信号对应的信号波长为： 3x l00000000m/s除以 850M 赫兹，即得其波长 λ为 0.352941m, 其 1/4倍即为约为 88.24mm, 因此，移动终端上作为馈线的导电件的长度只要是非 88.24mm 即可，并且，与 88.24mm 的差距越大越好，如可设置为 90mm以上；上述的馈线长度越长，谐振的频率也就越小，对移动终端天线的辅助性能影响也就越小。当然，也可以使上述的馈线小于 88.24mm, 只要不与移动终端支持的其他频段的天线馈线接近即可。 The length of the feed line provided on the metal piece of the mobile terminal body should be different from the length of the feed line of the existing antenna on the mobile terminal, which is considering the resonance in the existing PIFA antenna on the mobile terminal. The frequency is designed such that the resonant frequency generated by the feeder is different from the frequency of the wireless signal supported by the existing PIFA antenna, so that no radiation is generated on the frequency point supported by the mobile terminal antenna, thereby ensuring the antenna of the mobile terminal. performance. Specifically, the PIFA antenna requires a feed line length of 1/4λ, where λ is the wavelength of the signal to be received. The present invention sets the conductive member on the mobile terminal as the feed line of the antenna to avoid causing the original configuration of the antenna in the mobile terminal. Radiation performance impact. The frequencies supported by the mobile terminal antenna are generally GSM850, GSM900, DCS1800, PCS1900, W900, W1900, W2100. Taking the 850M Hz PIFA antenna in the mobile terminal as an example, the purpose of the present invention is to make the mobile terminal The conductive member forms an antenna that receives a signal different from the 850M as much as possible. The signal wavelength corresponding to the 850 MHz signal is: 3 x l000000000000 m/s divided by 850 M Hz, that is, the wavelength λ is 0.352941 m, which is about 1/4 times 88.24mm, therefore, the length of the conductive member as the feeder on the mobile terminal is not 88.24mm, and the larger the difference from 88.24mm, the better, for example, can be set to 90mm or more; the longer the feeder length, the frequency of resonance The smaller the impact, the smaller the auxiliary performance of the mobile terminal antenna. Of course, the above feeder can also be less than 88.24mm, as long as it is not close to the antenna feeder of other frequency bands supported by the mobile terminal.

具体的，所述已有天线包含 850MHz 天线时，所述馈线长度为不为 88.24mm的长度；所述已有天线包含 900MHz天线时，所述馈线长度为不为 83.33mm的长度；所述已有天线包含 1800MHz天线时，所述馈线长度为不为 41.67mm的长度；所述已有天线包含 1900MHz天线时，所述馈线长度为不为 39.47mm的长度；所述已有天线包含 2100MHz天线时，所述馈线长度为不为 35.71mm的长度；所述已有天线包含 2400MHz天线时，所述馈线长度为不为 31.25mm的长度。上述的长度均为理论值，具体取值视实际的通信天线设置而定。实际使用时，作为馈线的导电件的长度不大于 30mm, 或设置为 90mm以上即可。 Specifically, when the existing antenna includes an 850 MHz antenna, the length of the feeder is not 88.24 mm; when the existing antenna includes a 900 MHz antenna, the length of the feeder is not 83.33 mm; When the antenna includes an 1800 MHz antenna, the length of the feeder is not 41.67 mm; when the existing antenna includes a 1900 MHz antenna, the length of the feeder is not 39.47 mm; when the existing antenna includes a 2100 MHz antenna The length of the feeder is not longer than 35.71 mm; when the existing antenna comprises a 2400 MHz antenna, the length of the feeder is not longer than 31.25 mm. The above lengths are all theoretical values, and the specific values depend on the actual communication antenna settings. In actual use, the length of the conductive member as the feed line is not more than 30 mm, or may be set to 90 mm or more.

上述移动终端上的馈线，与移动终端已有天线的馈线长度差别越大，对已有天线的干扰越小。 The difference between the feeder line on the mobile terminal and the feeder length of the existing antenna of the mobile terminal is larger. The interference with existing antennas is smaller.

上述移动终端上的金属件，可以作为全球定位*** （ GPS , Global Positioning System ), 蓝牙或者是无线保真（ WIFI, Wireless Fidelity )频段的天线馈线（当移动终端不具有上述***的天线时），实现原理与前述 PIFA 天线原理相同，这里不再赘述其馈线长度的确定方式。 The metal parts on the mobile terminal can be used as an antenna feeder of a Global Positioning System (GPS), Bluetooth or a wireless fidelity (WIFI) band (when the mobile terminal does not have the antenna of the above system), The principle of implementation is the same as that of the aforementioned PIFA antenna. The determination of the length of the feeder line will not be repeated here.

上述的馈线设计，最好是曲线，以在有限的移动终端机体上满足该馈线的设计长度。 The feeder design described above is preferably curved to meet the design length of the feeder on a limited mobile terminal body.

上述的馈线，也可以设置于移动终端机体的其他部分，如设置于移动终端的后机壳上等。 The above feeder may also be disposed in other parts of the mobile terminal body, such as on the rear casing of the mobile terminal.

当移动终端的机壳为金属材质时，也可以在该移动终端的机壳上设置相应的馈线，具体的，可在移动终端机壳上开设槽而形成相应的馈线，将馈线的两端分别连接于移动终端天线的馈电点及接地点上即可。 When the casing of the mobile terminal is made of metal, a corresponding feeder may be disposed on the casing of the mobile terminal. Specifically, a slot may be formed on the casing of the mobile terminal to form a corresponding feeder, and the two ends of the feeder are respectively It can be connected to the feeding point and grounding point of the mobile terminal antenna.

本发明中，可在馈线的两端设置连接馈电点或接地点连接件，也可在馈电点及接地点上设置引线（分别相当于图 1中的馈电线、接地线），将相应引线与馈线连接即可。 In the present invention, a connection feeding point or a grounding point connecting member may be disposed at both ends of the feeding line, and a lead wire (corresponding to the feeding line and the grounding line in FIG. 1 respectively) may be disposed at the feeding point and the grounding point, correspondingly The lead wire can be connected to the feeder.

根据 PIFA天线的设计原理， PIFA天线的馈电面板上设置有接地点和馈电点，该馈电面板与天线的馈线所在的平面平行，两平行面之间的距离一般大于 6.5mm, 将天线的馈线分别连接于馈电面板上的接地点及馈电点即构成 PIFA天线。而天线馈线与馈电面板上的接地点及馈电点通过垂直于馈电面板的连接板连接。据此，上述馈电点及接地点的引线最好与馈线所在的平面垂直。 According to the design principle of the PIFA antenna, the feed panel of the PIFA antenna is provided with a grounding point and a feeding point. The feeding panel is parallel to the plane of the feeding line of the antenna, and the distance between the two parallel planes is generally greater than 6.5 mm. The feeders are respectively connected to the grounding point and the feeding point on the feeding panel to form a PIFA antenna. The antenna feed line and the grounding point and the feeding point on the feeding panel are connected by a connecting plate perpendicular to the feeding panel. Accordingly, the leads of the feed point and the ground point are preferably perpendicular to the plane in which the feed line lies.

当馈电点及接地点的引线能与馈线连接时，也可不必在馈线两端设置连接件。 When the leads of the feed point and the ground point can be connected to the feeder, it is not necessary to provide a connector at both ends of the feeder.

以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。 The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
