I-Corps: A Compact Low-Cost Wire Antenna Array for Dedicated Short Range Communications

该天线系统具有实现车对车和车对路边基础设施（V2V/V2I）系统的潜力，具有低成本、低姿态和增强的电气性能。天线系统包括满足汽车机械和制造要求的专用馈电网络。这种馈电网络使得新车在制造阶段的安装复杂性相对较低，更重要的是，它使售后改装成为可能，其中具有地平面独立特性的天线系统允许灵活地安装在车辆的不同位置（即在车顶，在车顶或仪表板上）。从本质上讲，拟议的天线将通过通信技术促进车辆安全的进步，并有助于DSRC标准支持潜在的车辆安全实施，特别是在IEEE 802.11标准修订为802.11p之后，该标准为DSRC规范了5.85 - 5.925 GHz的频率范围，允许高数据速率通信和低功率水平要求。拟议的天线系统对公共安全具有重要意义，因为它将增加使用智能交通系统（ITS）的车辆安全的进步。ITS旨在通过为乘客提供方便的应用程序，简化现代车辆的操作，管理车辆交通，协助驾驶员获取安全和其他数据。从商业化的角度来看，考虑到每年有8000万辆汽车进入市场，市场渗透率将强烈影响V2V/V2I安全和非安全应用的有效性。研究表明，即使所有新车在制造阶段就配备了DSRC应答器安全装置，要在全球汽车市场上达到95%的渗透率，也需要几十年的时间。这种天线系统将导致增强的“V2V和V2I通信”，因为车辆天线具有尽可能低的轮廓，以避免在外观上改变车辆外观，并允许容易和快速安装。

The proposed antenna system has the potential to allow simple implementation of Vehicle-to-Vehicle and Vehicle-to-Roadside Infrastructure (V2V/V2I) systems with low-cost, low profile, and enhanced electrical performance. The antenna system includes specific feed network which meets the automotive mechanical and manufacturing requirements. Such feed network allows relatively lower installation complexity for new vehicles during the manufacturing stage and more importantly, it enables aftermarket retrofit, where the antenna system with ground plane independent characteristic allows flexible installation at different positions of the vehicle (i.e. on the roof of the vehicle, in the headliner, or on the dashboard). In essence, the proposed antenna will facilitate the advancement of vehicle safety through communication technologies and contributes to DSRC standards in supporting potentoal vehicle safety implementations especially after the amendment of the IEEE 802.11 standard into 802.11p which regulates the frequency range of 5.85 - 5.925 GHz for DSRC allowing high data rate communications and low power level requirements.The proposed antenna system is significant to public safety as it will add to the advancement of vehicle safety using Intelligent Transportation Systems (ITS). ITS aim to streamline the operation of modern vehicles, manage vehicle traffic, assist drivers with safety and other data by providing convenience applications for passengers. From a commercialization prospective, considering 80 million vehicles enter the market every year, market penetration will strongly influence the effectiveness of V2V/V2I safety and non-safety applications. Studies have shown that it can take decades to reach 95% DSRC transponder safety device penetration in the global automobile market, even if all new vehicles are equipped during the manufacturing stage itself. This antenna system will lead to enhanced "V2V and V2I communications" as it is desirable for vehicle antennas to have the lowest possible profile in order to avoid cosmetically altering the vehicle's exterior look and to allow easy and quick installation.
