Novel Filter Topologies and Synthesis Techniques for Addressing the Challenges of Future Communication Systems

在当今的大多数通信系统中，工作频率和用户数量的快速增加以及宽带互联网、远程医疗和视频会议等新的应用对滤波器的电气和物理特性(尺寸和质量)提出了严格的要求，即对通信系统的性能起主要作用的部件。在移动基站和无线通信设备中，对微波滤波器的尺寸、体积和质量的要求越来越高。在每个通信系统中，滤波器设计确实是一个庞大的部分，为了解决这一问题，不仅应该考虑新颖的谐振结构，而且应该重新考虑涉及综合技术的滤波器设计的理论部分。因此，这一提议的主要目标是通过引入新的谐振结构和引入新的合成和建模方法来解决尺寸和质量减小的问题。我们将从理论上证明每个新概念，并将通过制造不同的原型来支持理论。本计划中提出的想法将适用于需要高效过滤器来应对未来通信系统挑战的不同场景。

In the majority of today’s communication systems, the rapid increase of the operating frequency and the number of users together with the new applications such as broadband internet, telemedicine, and video conferencing put stringent conditions on the electrical and physical characteristics (size and mass) of the filters, i.e. the components that play a major role in the performance of a communication system. The demand of size, bulk, and mass reduction of microwave filters is on the rise in mobile base stations and wireless communication devices. In order to deal with this issue in the area of filter design, which is indeed a bulky part of each communication system, not only novel resonant structures should be considered but also the theoretical part of the filter design which deals with the synthesis techniques should be reconsidered. Therefore the main goal of this proposal is to solve the issue of size and mass reduction through incorporating novel resonant structures and introducing novel synthesis and modeling approaches. We will prove each new concept theoretically and will support the theory by the fabrication of different prototypes. The proposed ideas in this plan will be applicable in different scenarios that require highly efficient filters for addressing the challenges of future communication systems.
