Critical upgrade for antenna characterization system

对在毫米波波段运行的便携式和高数据速率通信系统的需求，对设计和开发具有高增益和大带宽的紧凑、高效天线产生了至关重要的需求。此外，为了适应未来通信系统的发展，天线的高效性和紧凑性已成为天线研究领域一个具有挑战性的指标。从这个角度来看，我们提出了几个针对新型先进毫米波天线的研究项目。这些项目的主要里程碑包括数值设计、原型设计和实验表征，以开发在紧凑和高效方面具有高性能的新型天线。基于电磁场仿真的数值分析与设计已被应用于毫米波天线的设计。虽然，数值分析提供了更深入的了解初始设计和优化，准确的实验验证是必要的，以证明所提出的概念。前两个工具，即数值模拟软件和原型设备最近更新，并在我们的射频实验室中功能齐全。然而，最关键的毫米波天线表征设备急需硬件和软件升级。

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.
