摘要

本文提出了一种2.6 GHz方向图可重构的紧凑型天线系统的设计与评价。该天线基于电子操纵寄生阵列散热器(ESPAR)的概念，其高度通过顶部加载降低。该天线可产生10个可重构方向图，最大增益为7.4 dBi。此外，还提出了由这些天线组成的多天线系统。在前人研究成果的基础上，对多输入多输出(MIMO)系统实现的辐射方向图进行了优化。制造样机的s参数测量结果与仿真结果相吻合。此外，三维测量的辐射模式与模拟非常吻合，获得了高达8 dBi的增益。

A LOW-PROFILE PATTERN RECONFIGURABLE ANTENNA SYSTEM FOR AUTOMOTIVE MIMO APPLICATIONS

This paper presents the design and evaluation of a compact antenna system with pattern reconfigurability at 2.6 GHz. The antenna is based on the concept of an electronically steerable parasitic array radiator (ESPAR), and its height is reduced by top loading. The antenna can generate 10 reconfigurable patterns with a maximal gain of 7.4 dBi. Furthermore, a multiple antenna system consisting of these antennas is proposed. The radiation patterns realized by this multiple-input-multipleoutput (MIMO) system are optimized for automotive urban scenarios based on the results of previous research. The S-parameter measurement results of a fabricated prototype correlate with the simulation. Furthermore, 3D measurements of radiation patterns correspond very well with simulation and gain up to 8 dBi is obtained.
