背景技术 Background technique
随着现代无线通信技术的快速发展,电磁波作为信息传输的载体,发挥着越来越重要的作用。而天线,作为无线电设备中辐射或接收无线电波的装置,广泛应用于无线电通信装备、雷达、电子对抗设备和无线电导航等设备中。 With the rapid development of modern wireless communication technology, electromagnetic waves, as the carrier of information transmission, are playing an increasingly important role. Antenna, as a device for radiating or receiving radio waves in radio equipment, is widely used in radio communication equipment, radar, electronic countermeasure equipment and radio navigation equipment.
宽带及超宽带无线技术,由于其具有传输速率高、系统容量大等优点,在高速无线个域网、智能无线局域网、户外对等网络以及传感、定位和识别网络等众多领域有着广泛的应用。随着移动通信事业在世界范围内的迅猛发展,移动通信系统在不断演进。移动通信系统已经从第三代WCDMA、CDMA2000、TD-SCDMA移动通信系统,发展到目前广泛投入使用的第四代宽带无线移动通信网络IMT-Advanced系统。欧盟委员会在2013年12月表示,将与企业合作,分别拿出7亿欧元和30多亿欧元,用于第五代(5G)移动通信系统的研发。第五代移动通信系统将提供全新的技术,实现在任何地点都能建立起人与人、人与汽车等的联系,并计划在2020年实现5G应用。我国在2013年投入1.6亿人民币,启动国家863计划《第五代移动通信(5G)系统前期研究开发(第一期)》项目,“系统地研究5G移动通信体系构架、无线组网、无线传输、新型天线与射频以及新频谱开发与利用关键技术”。移动用户数的快速增长和用户数据量的急剧增加,对移动通信系统的容量和更新提出了巨大的挑战。 Broadband and ultra-broadband wireless technology, due to its advantages of high transmission rate and large system capacity, has been widely used in many fields such as high-speed wireless personal area network, intelligent wireless local area network, outdoor peer-to-peer network, and sensing, positioning and identification network. . With the rapid development of the mobile communication industry in the world, the mobile communication system is constantly evolving. The mobile communication system has developed from the third-generation WCDMA, CDMA2000, and TD-SCDMA mobile communication systems to the fourth-generation broadband wireless mobile communication network IMT-Advanced system that is widely used. The European Commission stated in December 2013 that it would cooperate with enterprises to allocate 700 million euros and more than 3 billion euros for the research and development of the fifth generation (5G) mobile communication system. The fifth-generation mobile communication system will provide brand-new technologies to establish connections between people, people and cars anywhere, and plans to implement 5G applications in 2020. my country invested 160 million yuan in 2013 to start the National 863 Program "Preliminary Research and Development of the Fifth Generation Mobile Communication (5G) System (Phase I)" project, "to systematically study the architecture of 5G mobile communication system, wireless networking, wireless transmission , new antennas and radio frequencies, and key technologies for the development and utilization of new spectrum.” The rapid increase in the number of mobile users and the sharp increase in the amount of user data pose a huge challenge to the capacity and update of mobile communication systems.
为了同时满足多个系统的通信要求,实现多系统共用和收发共用,也为了减小天线间的干扰并降低成本,当前比较成熟的技术是要求单个天线能在宽频带范围内工作。通过激励起单个天线的高次模,使得单天线工作在多谐振模式,从而拓展带宽。比较典型的是单极子天线。这种天线结构简单,加工成本低,能够实现几个倍频程的带宽。但是单极子天线在整个带宽内都工作在单极子模式,辐射方向图对单极子的电长度比较敏感。考虑到宽带及超宽带天线的带宽很宽,往往能达到几个倍频程,因而单极子的电尺寸在倍频程内变化了几倍,所以其辐射方向图在倍频程内畸变很严重,而且频率越高,畸变越明显。多谐振模式的单天线都存在这个问题。为了提高无线通信系统的有效性和保障无线通信系统的可靠性,也为了降低天线的成本,设计出在宽带和超宽带内保持稳定辐射方向图的平面型天线,对促进宽带无线通信的发展具有非常积极的贡献。 In order to meet the communication requirements of multiple systems at the same time, to achieve multi-system sharing and transceiver sharing, and to reduce the interference between antennas and reduce costs, the current relatively mature technology requires a single antenna to work in a wide frequency range. By exciting the high-order modes of a single antenna, the single antenna works in multiple resonance modes, thereby expanding the bandwidth. A typical example is a monopole antenna. This antenna has a simple structure, low processing cost, and can realize a bandwidth of several octaves. However, the monopole antenna works in the monopole mode within the entire bandwidth, and the radiation pattern is sensitive to the electrical length of the monopole. Considering that the bandwidth of broadband and ultra-wideband antennas is very wide, it can often reach several octaves, so the electrical size of the monopole changes several times in the octave, so its radiation pattern is very distorted in the octave Serious, and the higher the frequency, the more obvious the distortion. This problem exists for single antennas with multiple resonant modes. In order to improve the effectiveness of the wireless communication system and ensure the reliability of the wireless communication system, and to reduce the cost of the antenna, a planar antenna that maintains a stable radiation pattern in broadband and ultra-wideband is designed, which is of great significance to the development of broadband wireless communication. Very positive contribution.

Both the first U-shaped monopole 1 and the second U-shaped monopole 2 are connected in sequence by three microstrip lines with the same width, and the first U-shaped monopole 1 and the second U-shaped monopole 2 are microstrip The stripline widths are the same.
CPW馈线3与同轴探针相连,使用同轴探针进行馈电。 The CPW feeder 3 is connected to the coaxial probe, and the coaxial probe is used for feeding.
第一U形单极子1下臂1a、第二U形单极子2下臂2a同时作为CPW馈电结构的金属地板。 The lower arm 1a of the first U-shaped monopole 1 and the lower arm 2a of the second U-shaped monopole 2 also serve as the metal floor of the CPW feed structure.
如图1和2所示,介质基板5采用相对介电常数4.4、厚度1.6mm的FR4板材。所述第一U形单极子1、第二U形单极子2、CPW馈线3、CPW缝隙4均设置于介质基板5的同一面。 As shown in FIGS. 1 and 2 , the dielectric substrate 5 is made of FR4 plate with a relative permittivity of 4.4 and a thickness of 1.6 mm. The first U-shaped monopole 1 , the second U-shaped monopole 2 , the CPW feeder 3 , and the CPW slot 4 are all arranged on the same surface of the dielectric substrate 5 .
本发明的技术方案是这样实现的:如图1和图2所示的结构,当天线工作在较低频段时,第一U形单极子1和第二U形单极子2一起作为主辐射体,天线工作在单极子模式,调整第一U形单极子1和第二U形单极子2的总长度、第一U形单极子1和第二U形单极子2之间缝隙的相对位置和长度以及微带线宽带,可调节低频段的工作频率和阻抗匹配,此时电流分布集中在第一U形单极子1和第二U形单极子2上。如图1和图2所示的结构,当天线工作在中间频段时,第一U形单极子1作为主辐射体,天线工作在单极子模式,调整第一U形单极子1的长度和微带线宽度,可调节中间频段的工作频率和阻抗匹配,电流分布集中在第一U形单极子1上。如图1和图2所示的结构,当天线工作在较高频段时,天线工作为单极子模式,调整CPW馈线3的长度和宽度,可调节单极子模式的工作频率和阻抗匹配,电流分布集中在CPW馈线3上,CPW馈线3伸出金属地板部分长度约为四分之一个波长。因此,通过调整天线各参数,可激励起三个辐射单元,即低频段为第一U形单极1和第二U形单极子2作为主辐射体,中频段为第一U形单极子1作为主辐射体,高频段为CPW馈线3作为主辐射体,从而拓展了天线的工作带宽;由于天线在低频段、中频段和高频段都为单极子工作模式,具有相似的天线辐射图,因此本发明在整个工作频段内具有稳定的双向辐射特性。该发明的实施例的具体结果说明如下: The technical solution of the present invention is achieved in this way: with the structure shown in Figure 1 and Figure 2, when the antenna works in a lower frequency band, the first U-shaped monopole 1 and the second U-shaped monopole 2 together serve as the main Radiator, the antenna works in monopole mode, adjust the total length of the first U-shaped monopole 1 and the second U-shaped monopole 2, the first U-shaped monopole 1 and the second U-shaped monopole 2 The relative position and length of the gap and the broadband of the microstrip line can adjust the operating frequency and impedance matching of the low frequency band. At this time, the current distribution is concentrated on the first U-shaped monopole 1 and the second U-shaped monopole 2. As shown in Figure 1 and Figure 2, when the antenna works in the middle frequency band, the first U-shaped monopole 1 is used as the main radiator, and the antenna works in the monopole mode, and the first U-shaped monopole 1 is adjusted. The length and width of the microstrip line can adjust the working frequency and impedance matching of the intermediate frequency band, and the current distribution is concentrated on the first U-shaped monopole 1. As shown in Figure 1 and Figure 2, when the antenna works in a higher frequency band, the antenna works in a monopole mode, and the length and width of the CPW feeder 3 can be adjusted to adjust the operating frequency and impedance matching of the monopole mode. The current distribution is concentrated on the CPW feeder 3, and the length of the part of the CPW feeder 3 protruding from the metal floor is about a quarter wavelength. Therefore, by adjusting the parameters of the antenna, three radiating units can be excited, that is, the low frequency band is the first U-shaped monopole 1 and the second U-shaped monopole 2 as the main radiator, and the middle frequency band is the first U-shaped monopole The sub-1 is the main radiator, and the CPW feeder 3 is the main radiator in the high-frequency band, thus expanding the working bandwidth of the antenna; since the antenna is in the monopole working mode in the low-frequency band, mid-frequency band and high-frequency band, it has similar antenna radiation Figure, so the present invention has stable two-way radiation characteristics in the entire working frequency band. The specific result of the embodiment of the invention is described as follows:
天线尺寸可按照图1和图2所示:组成第一U形单极子(1)和第二U形单极子2的微带线宽度均为8.8mm。第一U形单极子1的下臂1a外长27.1mm,另一条臂外长16.7mm,中间段内长27.4mm。第二U形单极子2的下臂2a外长27.1mm,另一条臂外长34.7mm,中间段内长27.4mm。第一U形单极子(1)的上臂和第二U形单极子(2)的上臂之间的缝隙长6mm。CPW馈线3的长度为25.6mm,宽度为1.2mm。两个CPW缝隙4宽度均为1mm。介质基板5长度为45mm,宽度为57.4mm,厚度为1.6mm。根据以上尺寸制作的天线的反射系数仿真结果如图3所示,-10dB带宽为3.6087GHz,从1.7866GHz到5.3953GHz。以图1和图2所示尺寸制作的天线的辐射方向图的仿真结果如图4所示,其中图4(a)为天线工作在2GHz时X-Y平面与Y-Z平面辐射方向图;图4(b)为天线工作在3GHz时X-Y平面与Y-Z平面辐射方向图;图4(c)为天线工作在4.44GHz时X-Y平面与Y-Z平面辐射方向图。可以看到,在给定的频率上,天线都具有稳定的双向辐射特性。我们定义天线在不同频率上的3-dB波束宽度为两个方向(+Y与-Y)3-dB波束宽度的总和。图4(a)所示,天线工作在2GHz时X-Y平面,3-dB波束宽度为150°;Y-Z平面,3-dB波束宽度为110°。图4(b)所示,天线工作在3GHz时X-Y平面,3-dB波束宽度为150°;Y-Z平面,3-dB波束宽度为155°。图4(c)所示,天线工作在4.44GHz时X-Y平面,3-dB波束宽度为100°;Y-Z平面,3-dB波束宽度为120°。可见天线的3-dB波束宽度都很宽。图1和图2所示尺寸制作的天线的增益如图5所示,在1.78GHz到5.40GHz频带内,天线增益在3.65dB到7.18dB波动。 The dimensions of the antenna can be shown in Figure 1 and Figure 2: the width of the microstrip line forming the first U-shaped monopole (1) and the second U-shaped monopole 2 is both 8.8mm. The outer length of the lower arm 1a of the first U-shaped monopole 1 is 27.1 mm, the outer length of the other arm is 16.7 mm, and the inner length of the middle section is 27.4 mm. The outer length of the lower arm 2a of the second U-shaped monopole 2 is 27.1 mm, the outer length of the other arm is 34.7 mm, and the inner length of the middle section is 27.4 mm. The gap between the upper arm of the first U-shaped monopole (1) and the upper arm of the second U-shaped monopole (2) is 6mm long. The length of the CPW feeder 3 is 25.6 mm, and the width is 1.2 mm. Both CPW gaps 4 have a width of 1mm. The length of the dielectric substrate 5 is 45mm, the width is 57.4mm, and the thickness is 1.6mm. The simulation results of the reflection coefficient of the antenna made according to the above dimensions are shown in Figure 3, the -10dB bandwidth is 3.6087GHz, from 1.7866GHz to 5.3953GHz. The simulation results of the radiation pattern of the antenna made with the dimensions shown in Figure 1 and Figure 2 are shown in Figure 4, where Figure 4(a) is the radiation pattern of the X-Y plane and Y-Z plane when the antenna works at 2GHz; Figure 4(b ) is the radiation pattern of X-Y plane and Y-Z plane when the antenna works at 3GHz; Figure 4(c) is the radiation pattern of X-Y plane and Y-Z plane when the antenna works at 4.44GHz. It can be seen that at a given frequency, the antennas have stable two-way radiation characteristics. We define the 3-dB beamwidth of an antenna at different frequencies as the sum of the 3-dB beamwidths in both directions (+Y and -Y). As shown in Figure 4(a), when the antenna works at 2GHz, the X-Y plane has a 3-dB beamwidth of 150°; the Y-Z plane has a 3-dB beamwidth of 110°. As shown in Figure 4(b), when the antenna works at 3GHz, the X-Y plane has a 3-dB beamwidth of 150°; the Y-Z plane has a 3-dB beamwidth of 155°. As shown in Figure 4(c), when the antenna works at 4.44GHz, the X-Y plane has a 3-dB beamwidth of 100°; the Y-Z plane has a 3-dB beamwidth of 120°. It can be seen that the 3-dB beamwidth of the antenna is very wide. The gain of the antenna made with the dimensions shown in Figure 1 and Figure 2 is shown in Figure 5. In the 1.78GHz to 5.40GHz frequency band, the antenna gain fluctuates from 3.65dB to 7.18dB.
所述天线系统可以在45×57.4mm2的平面空间内,实现3.6087GHz(从1.7866GHz到5.3953GHz)的带宽,而且整个工作频带内具有稳定的双向辐射特性。 The antenna system can realize a bandwidth of 3.6087GHz (from 1.7866GHz to 5.3953GHz) in a plane space of 45×57.4mm 2 , and has stable bidirectional radiation characteristics in the entire working frequency band.
