Description
技术领域technical field
本发明属于无线电领域，特别是应用到手机天线。The invention belongs to the radio field, and is especially applied to mobile phone antennas.
背景技术Background technique
现有的大部分缝隙天线都需要较大的宽度来保证带宽，影响美观。另外己有的一些用微缝设计的天线装置，往往让缝隙与金属面的边缘相交，形成了开口，或者让缝隙切开两处边缘形成两个开口，开口处较难做弯曲处理且容易突出，影响天线的美观。而且，这些天线装置缝隙的位置受限，需靠近金属面边缘才能与之相交，无法移至全属面的中央。另外，从辐射原理上，这些天线装置不属于缝隙偶极子天线，无法在垂直缝隙的平面产生全向辐射。Most of the existing slot antennas require a relatively large width to ensure the bandwidth, which affects the appearance. In addition, some existing antenna devices designed with micro-slits often make the slit intersect with the edge of the metal surface to form an opening, or the slit cuts two edges to form two openings, and the opening is difficult to bend and easy to protrude , affecting the aesthetics of the antenna. Moreover, the positions of the slots of these antenna devices are limited, and they need to be close to the edge of the metal surface to intersect with it, and cannot be moved to the center of the entire metal surface. In addition, from the radiation principle, these antenna devices are not slot dipole antennas, and cannot generate omnidirectional radiation in a plane perpendicular to the slot.
发明内容Contents of the invention
本发明针对现有技术的缺陷，提供一种易加工、易生产、且具有较好隐藏特性且更加美观的缝隙偶极子天线。为解决上述技术问题，本发明采用的技术方案是：提供一种缝隙偶极子天线，由金属平面以及金属平面上的两条缝隙和一个馈电构成。所述天线为平面缝隙天线，进一步地，所述平面缝隙天线为金属平面内部开缝的天线,缝隙与金属平面边缘不相交且缝隙之间互不相交。更进一步地，所述平面缝隙天线的开缝为条状缝隙。更进一步地，所述条状缝隙的尺寸、数量和距离可根据天线的性能及阻抗匹配要求确定，并且缝隙的宽度较传统的缝隙天线的宽度大大减小。射频馈电端的接地端和激励端分别连接在两个缝隙中相距最远的边缘。射频馈电端的信号端射频电流需要绕过两个细缝到达射频馈电端的接地端，其电流环绕路径与传统的缝隙天线的电流环绕路径相同，因此除了两个细缝之间的区域，金属平面上的电流分布和传统缝隙相比基本相同，因此本发明中的缝隙偶极子天线的性能和传统缝隙天线相似。Aiming at the defects of the prior art, the invention provides a slot dipole antenna which is easy to process and produce, has better hiding characteristics and is more beautiful. In order to solve the above technical problems, the technical solution adopted by the present invention is: to provide a slot dipole antenna, which is composed of a metal plane, two slots on the metal plane and a feeder. The antenna is a planar slot antenna. Further, the planar slot antenna is an antenna with slots inside a metal plane, and the slots do not intersect with edges of the metal plane and do not intersect with each other. Furthermore, the slots of the planar slot antenna are strip-shaped slots. Furthermore, the size, quantity and distance of the strip-shaped slots can be determined according to the performance of the antenna and the requirement of impedance matching, and the width of the slots is much smaller than that of the traditional slot antenna. The ground terminal and the excitation terminal of the radio frequency feed terminal are respectively connected to the farthest edge of the two slots. The RF current at the signal end of the RF feed end needs to go around two slits to reach the ground end of the RF feed end, and its current winding path is the same as that of a traditional slot antenna. Compared with the traditional slot, the current distribution on the plane is basically the same, so the performance of the slot dipole antenna in the present invention is similar to that of the traditional slot antenna.
与现有缝隙偶极子阵列天线技术相比，有益效果是：本发明的带宽可以不受到缝隙的宽度限制，通过增大缝隙的距离来改善带宽。而达到隐藏和美化的效果，同时不牺牲带宽。与现有的微缝天线结构相比，本发明的缝隙不与金属面的边缘相交，不需要在金属平面边缘形成开口，而且没有位置的限制，另外辐射原理上属于缝隙偶极子天线，具有更好的全向辐射特性。Compared with the existing slot dipole array antenna technology, the beneficial effect is that the bandwidth of the present invention is not limited by the width of the slot, and the bandwidth is improved by increasing the distance of the slot. To achieve the effect of hiding and beautifying without sacrificing bandwidth. Compared with the existing micro-slot antenna structure, the slot of the present invention does not intersect with the edge of the metal surface, does not need to form an opening at the edge of the metal plane, and has no position restrictions. In addition, the radiation principle belongs to the slot dipole antenna, which has Better omnidirectional radiation characteristics.

图2所示是本发明中的缝隙偶极子天线和传统缝隙天线的谐振电流对比图；可以看到本发明中的缝隙偶极子天线的电流环绕路径与传统的缝隙天线的电流环绕路径相同，因此除了两个细缝之间的区域，金属板上电流分布和传统缝隙相比基本相同，故而本发明中的缝隙偶极子天线的性能和传统缝隙天线相似。Shown in Fig. 2 is the resonant current contrast figure of slot dipole antenna among the present invention and traditional slot antenna; It can be seen that the current encircling path of slot dipole antenna among the present invention is identical with the current encircling path of traditional slot antenna , so except for the area between the two slits, the current distribution on the metal plate is basically the same as compared with the conventional slot, so the performance of the slot dipole antenna in the present invention is similar to that of the conventional slot antenna.
图3所示是本发明中的缝隙偶极子天线作为WLAN天线例子时，与传统缝隙天线相比的回波损耗即S11曲线，可以看到与传统缝隙天线相比，本发明中的缝隙偶极子天线的带宽与效率与其相近，并且在WLAN的工作频段内(2400.0MHz-2483.5MHz)S11约在-15dB以下，实现较好的阻抗匹配，将能量较好的辐射出去。Shown in Fig. 3 is that when the slot dipole antenna in the present invention is used as the WLAN antenna example, the return loss compared with the traditional slot antenna is the S11 curve, and it can be seen that compared with the traditional slot antenna, the slot dipole antenna in the present invention The bandwidth and efficiency of the pole antenna are similar to it, and in the working frequency band of WLAN (2400.0MHz-2483.5MHz), the S11 is below -15dB, which achieves better impedance matching and radiates energy better.
图4所示是本发明中的缝隙偶极子天线和传统缝隙天线在2.4GHz上的水平面辐射方向图，可见两种天线在各个方向的辐射能力几乎相同，且在0°和180°方向辐射均为0，这是由于电流源在其轴向都无辐射；除了该方向外其他方向保持较好的辐射能力。Shown in Fig. 4 is the horizontal plane radiation pattern of slot dipole antenna among the present invention and traditional slot antenna on 2.4GHz, as seen two kinds of antennas are almost identical in the radiation ability of each direction, and radiate in 0 ° and 180 ° direction Both are 0, because the current source has no radiation in its axial direction; except for this direction, other directions maintain good radiation ability.
图5所示是本发明采用多缝结构的外观示意图条状缝隙的尺寸、距离和数量可根据天线的性能及阻抗匹配要求确定。FIG. 5 is a schematic view of the appearance of the multi-slit structure of the present invention.
