Critical upgrade for antenna characterization system

对工作在毫米波频段的便携式和高数据速率通信系统的需求产生了对设计和开发紧凑、高效、高增益和大带宽的天线的迫切需求。此外，为了顺应未来的通信系统，效率和紧凑性已经成为天线研究领域的一个具有挑战性的指标。从这个角度来看，我们提出了几个研究项目，目标是新型先进的毫米波天线。这些项目的主要内容包括数值设计、原型制作和实验表征，以开发具有紧凑性和高效率的新型天线。采用基于电磁场模拟的数值分析和设计方法设计毫米波天线。虽然数值分析为初始设计和优化提供了更深入的见解，但必须进行准确的实验验证才能证明所提出的概念。头两个工具，即数值模拟软件和原型设备，最近在我们的射频实验室进行了更新，并完全发挥了作用。然而，毫米波天线最关键的设备需要迫切的硬件和软件升级。

Demands for portable and high data-rate communication systems operating at millimeter-wave bands have created a crucial need for the design and development of compact, efficient antennas with high gain and large bandwidth. In addition, in order to comply with the future communication systems, efficiency and compactness has become a challenging figure of merit in the field of antenna research. In this perspective, we have proposed several research projects that target new advanced millimeter-wave antennas. The major mile stones of these projects involve, numerical design, prototyping and experimental characterization in order to develop novel antennas with high performances in terms of compactness and efficiency. The numerical analysis and design based on electromagnetic field simulations have been used to design mm-wave antennas. Although, numerical analysis provides a deeper insight to the initial design and optimization, accurate experimental validation is mandatory to prove the proposed concept. The first two tools, that are numerical simulation software and prototyping facility are recently updated and are fully functional in our RF laboratory. However, the most critical facility for mm-wave antenna characterization needs urgent hardware and software upgrade.
