【摘要】：随着移动通信技术的高速发展,第四代移动通信系统技术(4G)已经进入了商业化阶段,因此需要设计出尺寸小、性能优良,并且能够支持多个通信频段的终端天线。LTCC天线因其体积小、性能优越、不易被损坏等优点,近年来成为了很多学者研究的热点。本文采用LTCC技术的优势,设计了两款结构新颖的多频带天线。本文的主要工作有:1.首先介绍了LTCC天线发展现状。接下来介绍了天线的一些基本技术指标,着重介绍了天线小型化以及实现多频带的一些方法,为后面的章节做了理论准备。2.结合LTCC的特点,采用环形绕线的结构形式,提出了一款适用于GSM900、DCS1800、TD-SCDMA、TD-LTE的多频带终端天线。本文较为详细的阐述了该天线的设计与实现过程,包括:天线各个通带的逐一实现,天线低频带宽的扩展,天线反射系数的进一步降低,以及天线测试结果的误差分析。在距离天线底端0.1mm处引入一条环形线,实现了一款双通带天线。在距天线顶端0.1mm处引入第二条枝节,并通过金属柱将上下两金属条连通,形成了一款三通带天线。通过增加谐振枝以产生参差谐振的方法实现了天线低频带宽的扩展。通过在天线馈电端加上一块金属片使得天线反射系数进一步的降低。所有通带内天线的反射系数都小于-6dB。天线反射系数、方向图及增益的测量结果都在误差范围内。天线的最终尺寸为17.8mm×6mm×0.8mm。3.针对GSM900、TD-SCDMA、TD-LTE三个通信频段,在螺旋曲折线结构的基础上,增加耦合结构实现了LTCC天线的多频带。本文系统的分析了螺旋圈数、螺旋横截面积、曲折线以及耦合辐射片位置对天线性能的影响。分析表明,螺旋圈数及耦合辐射片位置对天线谐振频率有较大影响。最终设计的天线尺寸为16mm×5mm×1.2mm,GSM900频带内天线反射系数小于-7.5dB,TD-SCDMA、TD-LTE频带内反射系数小于-10dB。
[Abstract]:With the rapid development of mobile communication technology, the fourth generation mobile communication system (4G) technology has entered the stage of commercialization, so it is necessary to design small size and excellent performance. And the terminal antenna. LTCC antenna which can support multiple communication bands has become a hot research topic in recent years because of its small size, superior performance and not easy to be damaged. Based on the advantage of LTCC technology, two novel multi-band antennas are designed in this paper. The main work of this paper is: 1. Firstly, the development of LTCC antenna is introduced. Then some basic technical specifications of antenna are introduced, especially the miniaturization of antenna and some methods to realize multi-band. According to the characteristics of LTCC, a multi-band terminal antenna suitable for GSM900 DCS1800 TD-SCDMA-TD-LTE is proposed. In this paper, the design and implementation of the antenna are described in detail, including the realization of each band of the antenna, the expansion of the antenna's low frequency bandwidth, the further reduction of the antenna's reflection coefficient, and the error analysis of the antenna test results. A double pass band antenna is realized by introducing a ring line at the bottom of the antenna 0.1mm. The second branch is introduced from the top of the antenna 0.1mm, and the upper and lower metal strips are connected through the metal column to form a three-way band antenna. The antenna low frequency bandwidth is extended by adding resonance branches to produce staggered resonance. The antenna reflection coefficient is further reduced by adding a metal sheet to the antenna feed end. The reflection coefficient of all antennas in the passband is less than -6 dB. The measurement results of antenna reflection coefficient, pattern and gain are within the error range. The final size of the antenna is 17.8mm 脳 6mm 脳 0.8mm. 3. Aiming at the three communication bands of GSM900 TD-SCDMA-TD-LTE, the coupling structure is added to realize the multi-band of LTCC antenna on the basis of the spiral winding line structure. In this paper, the effects of the number of helical coils, spiral cross section, zigzag line and position of coupling radiator on the antenna performance are analyzed systematically. The analysis shows that the number of coils and the position of the coupling radiator have great influence on the resonant frequency of the antenna. The size of the designed antenna is 16mm 脳 5mm 脳 1.2 mm GSM 900 band antenna reflection coefficient is less than -7.5 dBU TD-SCDMA-TD-LTE frequency band reflection coefficient is less than -10 dB.
