摘要

2.45 GHz ISM频段的模式可重构天线隐藏在机箱天线腔内。三个天线被设计为通过在前/后和左/右辐射之间切换，在接近最佳的辐射模式之间重新配置城市场景。三种天线遵循不同的设计原则，具有不同的增益切换能力。天线性能是基于增益方向图测量来评估的。如图所示，天线保留其重新配置功能，当他们被放置在底盘腔下的车辆的车顶。

Automotive pattern reconfigurable antennas concealed in a chassis cavity

Pattern-reconfigurable antennas for the 2.45 GHz ISM band are concealed inside a chassis antenna cavity. Three antennas are designed to reconfigure between near-optimum radiation patterns for urban scenarios by toggling between front/back and left/right radiation. The three antennas follow distinct design principles and have different gain switching capabilities. Antenna performance is evaluated based on gain pattern measurements. It is shown, that the antennas retain their reconfiguration functionality when they are placed in the chassis cavity beneath the vehicle's roof.
