Abstract

This paper presents a simple and powerful design of a closely C-shaped microstrip patch antenna for wireless access in vehicular environment. Other wireless technologies such as WLAN, WiMAX, C-band, 5GHz U-NII, X-band and Ku-band applications are also supported. The microstrip patch antenna has been designed on the FR-4 substrate of 4.4 and thickness of h = 1.5mm, with a whole dimension of 25mm × 22mm. The proposed antenna can synchronously operate in multiple frequencies, covering four bands: [2.3538GHz-2.5388GHz], [5.0243GHz-8.0607GHz], [9.2403GHz-10.595GHz], [12.67GHz-15.182GHz]. To being small size, the new antenna exhibits stable far field radiation characteristics in the entire operating bandwidth with a relatively high gain, especially in the broadside direction which is suitable for vehicular systems. Using a full wave electromagnetic commercial simulator CST, a comprehensive study is detailed to understand the characteristics of the antenna in terms of electrical performances by considering reflection coefficient, radiation patterns, gain and VSWR. Results show, that the antenna is suitable for multiband wireless communication systems.

车载通信四波段紧凑型印刷天线设计

本文提出了一种简单而功能强大的车载无线接入紧密c型微带贴片天线设计方案。其他无线技术，如WLAN, WiMAX, c波段，5GHz U-NII, x波段和ku波段应用也支持。微带贴片天线设计在FR-4衬底4.4，厚度h = 1.5mm，整体尺寸为25mm × 22mm。该天线可在多个频率下同步工作，覆盖[2.3538GHz-2.5388GHz]、[5.0243GHz-8.0607GHz]、[9.2403GHz-10.595GHz]、[12.67GHz-15.182GHz]四个频段。新型天线体积小，在整个工作带宽内具有稳定的远场辐射特性，具有较高的增益，特别是在宽频方向上，适合车载系统使用。利用全波商用电磁模拟器CST，从反射系数、辐射方向图、增益和驻波比等方面对天线的电学特性进行了详细的综合研究。结果表明，该天线适用于多波段无线通信系统。
