Abstract

A quad-element multiple-input-multiple-output (MIMO) antenna with ultra-wideband (UWB) performance is presented in this paper. The MIMO antenna consists of four orthogonally arranged microstrip line-fed hexagonal monopole radiators and a modified ground plane. In addition, E-shaped and G-shaped stubs are added to the radiator to achieve additional resonances at 1.5 GHz and 2.45 GHz. The reliability of the antenna in the automotive environment is investigated, with housing effects taken into account. The housing effects show that the antenna performs consistently even in the presence of a large metal object. The proposed MIMO antenna has potential for various automotive applications, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X), intelligent transport system (ITS), automatic vehicle identifier, and RFID-based electronic toll collection.

摘要

本文提出了一种具有超宽带（UWB）性能的四元多输入多输出（MIMO）天线。该MIMO天线由四个正交排列的微带线馈电六边形单极辐射器和一个改进的接地平面组成。此外，在辐射器上添加了E形和G形短截线，以在1.5 GHz和2.45 GHz处实现额外的谐振。考虑了外壳效应，研究了该天线在汽车环境中的可靠性。外壳效应表明，即使存在大型金属物体，该天线仍能保持一致的性能。所提出的MIMO天线在各种汽车应用中具有潜力，包括车对车（V2V）、车对基础设施（V2I）、车对万物（V2X）、智能交通系统（ITS）、自动车辆识别以及基于射频识别（RFID）的电子收费。
