平面印刷天线的设计

【摘要】：在本世纪，电子技术和无线通信技术得到了迅速发展。作为现代无线通信系统中的重要组成部分，它们经常需要具有小天线，多频带和宽带特性。目前，由于采用先进的印刷电路板技术和工艺，印刷天线，因为易加工，重量轻，低轮廓，容易与有源器件和微波电路集成的特点已经广泛的关注和研究。微带贴片天线具有良好的指向性图案，在双极化和圆极化方面容易实现，适合阵列的组合从而得到一个高增益;印刷单极和隙缝天线全向性好，容易实现多频带和宽带特性，这些平面印刷天线被广泛用于雷达，卫星通信，移动通信和其他通信设备之间。因此，对平面印刷天线的研究有着很大的价值和实际意义。在本文中，结合科研的需要和各种无线通信系统的需求，对双极化微带阵列天线和多频带和宽频带平板天线的印刷的相关几个问题展开了研究。本文先是对国内天线技术进行了分析，了解了一下国内外对平面印刷天线的研究的情况，并且了解了对该技术研究的现状，并且重点研究了多层双极化微带阵列天线技术和多频带平面印刷天线设计，并对它们做了一系列的研究的分析。对多层双极化未带阵列天线技术主要分析了单脉冲技术、双极化微带天线、以及阵列的排布方式和其方向图的估算方面。最后并且对结果做了分析。在多频带平面印刷天线设计方面主要讲解了多频段环形单极天线、加载曲折线枝节的矩形环天线和双频段U形环天线方面，并且做了一系列的研究，展示研究结果。研究了多频带平面印刷天线的相关方面。通过在矩形环内部加载直线枝节和曲折线枝节，设计出两种三频带矩形环单极天线，可用于WLAN/WiMAX 2.5/3.5/S.SGHz无线通信。

PLANAR PRINTED ANTENNA DESIGN

Abstract: In this century, electronic technology and wireless communication technology has been developing rapidly. As modern wireless communication system, an important part, they often need to have a small antenna, a multiband and wideband characteristics. Currently, the use of advanced printed circuit board technology and processes, printed antenna, because easy processing, light weight, low profile, easy to integrate with active devices and microwave circuit characteristics have been widespread concern and research. Microstrip patch antenna having excellent directivity pattern, in terms of dual-polarization and circular polarization easy to implement, for the combination of the array to thereby obtain a high gain; printed monopole slot antenna and omni-directional, and easy to realize multi-band and broadband characteristic, which is widely used in print between the radar antenna, satellite communications, mobile communications and other communications devices. Therefore, the study of planar printed antenna has a great value and practical significance. In this paper, combined with the needs of research needs and various wireless communication systems, several issues related dual-polarized microstrip array antenna and multi-band and wideband planar antenna printed launched a study. This article first domestic antenna techniques are analyzed, learned about the situation at home and abroad to study planar printed antenna and understand the current situation of the research of technology, and focuses on the multi-layer dual-polarized microstrip antenna array technology and multiple band planar printed antenna design, and they did a series of studies of the analysis. Not multilayer dual polarized antenna array technology with mainly analyzes the single-pulse technology, dual-polarized antenna, and estimating aspects of the way the array arrangement and its pattern. Finally, and the results were analyzed. In the multi-band planar printed antenna design mainly on the multi-band monopole antenna ring, loaded meander line stub rectangular loop antenna and dual-band U-shaped loop antenna connection, and did a series of studies showing the results. We study the relevant aspects of the multi-band planar printed antenna. Through the rectangular ring inside and meander line loaded straight stub minor, designed two tri-band monopole antenna rectangular ring, can be used to WLAN / WiMAX 2.5 / 3.5 / S.SGHz wireless communications.
