摘要

为智能交通系统设计了一种全向超宽带(UWB)天线,该天线安装在汽车车顶的鲨鱼鳍罩中。该超宽带平面单极天线由改进单极天线和寄生条形馈电结构组成,在31.5mm × 38.2mm × 1.6mm的限制尺寸下,可产生2.6 ~ 5.0GHz的带宽。获得了优于4.4dBi的中等增益。它很容易由印刷电路板和金属板制成,工艺和材料成本低。天线特性已经优化,以确认在汽车应用中使用超宽带定位的可能性。

Design on An UWB Antenna in the Vehicular Shark-fin Housing on the Roof of a Car
An omni-directional Ultra Wide Band (UWB) antenna which is installed in shark-fin housing on the roof of a car is designed for Intelligent Transportation System. This UWB planar monopole antenna consists of a modified monopole antenna and parasitic strip feeding structure, which can generate a bandwidth from 2.6GHz to 5.0GHz, in a limited size of 31.5mm × 38.2mm × 1.6mm. A moderate gain, which is better than 4.4dBi, is obtained. It is easily fabricated from a printed circuit board and a metal sheet with low-cost process and materials. The antenna characteristics have been optimized to confirm the possibility for use of UWB locating in automotive applications.
