中文摘要: 高增益高效率天线是实现长距、超高速毫米波亚毫米波无线通信的关键部件,其优化设计是亟待解决的关键技术。在毫米波亚毫米波段,传统平面传输线的辐射损耗和金属损耗显著增加,是高增益高效率天线阵列实现的瓶颈。此外,天线与射频电路之间的转接损耗大,天线特性对加工公差和装配误差极为敏感。因此,天线的平面集成和一体化设计将是解决以上问题的有效途径。基于准周期结构的反射阵和传输阵,采用空间馈电方式,可以避免复杂馈电网络和馈电损耗,同时还具有低剖面、轻量化和易安装等特点。本项目将主要研究适用于毫米波亚毫米波平面集成反射阵和传输阵的优化设计和分析方法,包括研究设计和采用基于基片集成技术的平面天线作为馈源,进行联合优化设计;同时采用解析法分析影响该频段反射阵和传输阵效率的关键因素用于进一步提高效率;并试制天线样品进行验证。预期成果将为高增益高效率毫米波亚毫米波平面集成反射阵和传输阵的设计提供理论依据和技术支撑。

英文摘要: High-gain high-efficiency antenna is the key component for long-rang ultra-throughput millimeter-wave and sub-millimeter-wave wireless communication system, and its optimal design is the key technique that urgently needs to be solved. In millimeter-wave and sub-millimeter-wave bands, conventional planar transmission lines suffer from severe radiation loss and conductor loss, which is the bottle neck for the realization of high-gain high-efficiency antenna arrays. In addition, in these bands, the transition between the antenna and RF circuits will cause significant insertion loss, and the performance of the antenna is very sensitive to the fabrication error and installation error. Therefore, the planar integrated design of the antenna will be an effective way to overcome the above problems. Composed of quasi-periodic structures, reflectarrays and transmitarrays adopt the space feeding scheme to avoid additional complicated feeding networks and corresponding feeding loss, and simultaneously they features low profile, low weight, easy installation, and etc.. In this project, it mainly focuses on the research of the optimal design and analysis method that are suitable for millimeter-wave and sub-millimeter-wave planar integrated reflectarrays and transmitarrays, including the research on the design of substrate inte
