摘要
本文提出了一种可应用于 ISM 波段的双频（2.4/5.8 GHz）可穿戴 MIMO 天线系统。天线元件采用改进的共面波导馈电结构。通过天线元件的自解耦结构和正交放置，四元件天线系统实现了天线元件之间的高隔离度。浮地结构的使用有效抑制了背辐射。通过共面波导馈电和浮地的结合，该天线不仅外形小巧，而且提高了天线辐射的前后比，降低了 SAR 值。该天线还使用毛毡作为柔性介质基板，导电布作为辐射元件，使天线具有柔性。
Design of a dual-band wearable flexible MIMO antenna system for ISM band applications
This article proposes a dual-band (2.4/5.8 GHz) wearable MIMO antenna system that can be applied to the ISM band. The antenna element uses an improved coplanar waveguide feeding structure. The four-element antenna system achieves high isolation between antenna elements through the self-decoupling structure of the antenna element and the orthogonal placement. The use of a floating ground structure effectively suppresses back radiation. Through the combination of coplanar waveguide feeding and floating ground, the antenna not only has a low profile but also improves the front-to-back ratio of antenna radiation, reducing the SAR value. The antenna also uses felt as a flexible dielectric substrate and conductive cloth as a radiation element, making the antenna flexible.
期刊介绍：
Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal.
Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies.
RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
