中文摘要： 低温共烧陶瓷（LTCC）技术是实现微波元器件及组件小型化、轻量化和高性能的有效方法。在以往的LTCC电路（如滤波器）设计中，设计方法主要可以分为三类：集总、半集总、分布参数法。前两种方法主要适用于较低频段；分布参数法适用于高频且可简化电路设计，但电路体积往往过大。鉴于此，本课题将开展LTCC传输线谐振器小型化建模及其应用研究。通过在水平和垂直两个方向上对半波长带状线谐振器进行有序对称弯折，同时利用其内部存在的慢波效应，构建三维紧凑的传输线谐振器模型，并提出建模方法和准则。对称面形成的虚拟地将有利于该谐振器的精确建模和特性分析。进而利用该谐振器设计出结构紧凑的各种单端/平衡/巴伦式滤波电路以满足不同的需求。同时深入探索其在微波有源电路中的应用，通过表面贴装或内埋IC芯片，设计出小型化的电调谐振器，并应用在各种电调滤波电路和压控振荡器中，拓展该谐振器的应用范围，凸显其实用价值。

英文摘要： LTCC (low temperature co-fired ceramic) technology has recently attracted much attention as it can be effectively used to achieve compact size, light weight and high performance in various microwave components and devices. In the past, many LTCC circuits, such as filters, were conventionally implemented using three design methods, i.e. lumped element, semi-lumped element and distributed element. The first two, nevertheless, are usually only good in lower frequency ranges. Design method involving distributed element, which is applicable in higher frequency ranges, can significantly facilitate the microwave circuit designs for various application. However, the distibuted circuit size is always too large. In view of this point, this project aims at conducting the research on the modeling of compact LTCC transmission line resonator, along with exploring its applications in various LTCC components and circuits. Half-wavelength stripline resonator is regularly and symmetrically folded in the horizontal and vertical directions for modeling a three dimension (3-D) compact transmission line resonator. Because of the inner slow wave effect of the proposed resonator, its size reduction can be enhanced. The approaches and guidelines of the modeling are extensively investigated in this project to study this resonator. The sy
