【摘要】 60-GHz技术是挑战无线视频和数据传输速度的技术,它有许多优点,例如,频谱可用性60GHz可达到7GHz,而802.11n和UWB只达到0.66GHz和1.5GHz～7.5GHz。此外,60-GHz原始数据的最高速度达到25000Mbps,而802.11n标准和UWB只能分别实现600Mbps和480Mbps的传输速度。对于60-GHz天线研究,目前的主要研究工作集中在线极化上。圆极化对于线极化有明显的降低极化失配的优势,因此60-GHz圆极化天线的研究还有待提高。针对以上研究背景,本文建立了以多层LTCC工艺为基础,研究和发展适用于60-GHz频段圆极化天线阵列。主要内容为:第一章为绪论,主要概述了本文研究工作的背景。介绍60-GHz通信的发展现状、应用的领域;当前60-GHz天线的主要研究内容;并说明了本文的主要工作。第二章给出了宽带、圆极化螺旋天线的相关理论。第三章介绍本文的主要工作,设计基于LTCC技术,适用于60-GHz频段无线局域网的新型宽带集成天线,以及加工后实物的相关测试参数。第四章基于LTCC技术,利用差分馈电设计一种简单形式的60-GHz圆极化天线。第五章结束语,总结本文的主要工作和不足之处。更多还原

【Abstract】 60-GHz technology is the challenge of wireless video technology and data transfer speed. It has a lot of advantages like wide frequency bandwidth about 7 GHz, while 802.11n and UWB can only get 0.66GHz and 1.5GHz~7.5GHz. The maximum raw data rate of 60-GHz is up to 25000Mbps, while 802.11n and UWB standard can only up to 600Mbps and 480Mbps, respectively.For 60-GHz antenna research, current research focused on the line polarization. For linear polarization circular polarization has the significant advantages of reducing polarization mismatch, and the research of 60-GHz circularly polarized antenna can be improved.As for the background from above, this paper established a multi-layer LTCC technology, based on research and development for 60-GHz-band circularly polarized antenna array.The main contents of the paper are:Chapter I is an introduction, an overview of the research progress and development trend of 60-GHz integrated antennas and packaging technology. And describe the main work of this paper.Chapter II gives related theories of the wideband circularly polarized helical antenna technology.Chapter III describes the design of integrated helical antenna array based on LTCC for 60-GHz short-range wireless communication,giving the detailed design process and measurement results of the proposed antennas in this paper.Chapter IV based on LTCC technology, design a simple structure of 60-GHz circularly polarized antenna using differential feed technology.Chapter V presents full summary.更多还原
