Modelling Microwave & Millimeter Wave Printed Antennas and Integrated Circuit Transitions on Anisotropic Substrate- Superstate Geometries

提出的研究涉及集成电路不连续（如同轴到微带）和用于微波和毫米波应用的印刷电路天线的理解和建模。例如，PI在集成电路天线研究方面的最新进展表明，两层衬底-叠层结构可以在更高的增益、效率、模式全向性和带宽方面产生优势。大多数用作衬底的材料都具有各向异性，如果在建模中忽略这一点，则会导致误差随着频率的增加而增加。为了提供开发高频单片器件所需的高效计算机辅助设计（CAD）算法，对这些效应进行精确的频率相关建模是非常重要的。

The proposed research pertains to the understanding and modelling of integrated circuit discontinuities (such as coax to microstrip) and printed circuit antennas for microwave and millimeter wave applications. Recent advances by the PI in studies of integrated circuit antennas, for example, have shown that a two layer substrate-superstrate configuration can yield advantages in higher gain, efficiency, pattern omnidirectionality, and bandwidth. Most materials in use as substrates have anisotropy which if neglected in modeling contributes to errors that increase with frequency. It is important to obtain accurate frequency dependent modelling of these effects in order to provide the efficient computer-aided-design (CAD) algorithms needed in the development of very high frequency monolithic device.
