Abstract

Abstract In this article, a planar dual-element frequency reconfigurable multiple-input multiple-output (MIMO) antenna for ultra-wideband (UWB) applications is studied. The frequency band can be switched between UWB operation and single band rejected UWB performance using a pair of PIN diodes in the MIMO configuration. The presented antenna is comprised of two similar slotted circular radiators, having tapered microstrip feedlines and separate partial ground planes. An RT/Duroid 5880 substrate with size 54 × 54 mm2 is used for the design purpose. Rotational symmetry between the radiators and diagonally oriented t-shaped decoupling structure behind the substrate have been utilized for high isolation purpose. The designed MIMO antenna exhibits UWB performance in mode 1. In other mode, the antenna operates in the frequency range 2.46–10.44 GHz with Worldwide Interoperability for Microwave Access (WiMAX) band rejection. Thus, the MIMO antenna exhibits on-demand single band rejection behavior depending on the switching conditions of the diodes. The measured isolation is greater than −20 dB in both the modes. The presented MIMO configuration possesses compact and planar geometry with high gain, good isolation, ultrawideband performance with reconfigurable band elimination, high efficiency and efficient diversity performance parameters. The suggested antenna is a good choice to be utilized for portable UWB MIMO applications.

高隔离频率可重构UWB-MIMO天线，按需WiMAX频段消除

摘要本文研究了一种用于超宽带(UWB)应用的平面双元频率可重构多输入多输出(MIMO)天线。使用MIMO配置中的一对PIN二极管，可以在UWB操作和单波段拒绝UWB性能之间切换频带。所提出的天线由两个相似的开槽圆形辐射体组成，具有锥形微带馈线和独立的部分接地面。设计使用尺寸为54 × 54 mm2的RT/Duroid 5880基板。利用辐射体之间的旋转对称和衬底后的斜向t形去耦结构实现了高隔离。所设计的MIMO天线在模式1下具有超宽带性能。在其他模式下，天线工作在2.46-10.44 GHz频率范围内，具有全球微波接入互操作性(WiMAX)频带抑制。因此，MIMO天线表现出依赖于二极管开关条件的按需单带抑制行为。在两种模式下，测量到的隔离度都大于−20 dB。所提出的MIMO结构具有紧凑的平面结构、高增益、良好的隔离性、可重构带消除的超宽带性能、高效率和高效的分集性能参数。建议的天线是一个很好的选择，用于便携式UWB MIMO应用。

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.
