摘要

提出了一种减小背辐射的毫米波宽带印刷天线阵列。扇形覆盖天线由8个ASP元件组成，以提供宽带阻抗和辐射性能，并由8个反射元件组成，以提高前后比。尽管在毫米波频率上可用的材料有限，但由于这些元件明显具有许多自由度，因此可以很容易地设计反射元件。新阵列在整个ka波段的前后比测量值大于30 dB。由于这种天线的宽带特性，它可以被整合到众多毫米波无线电服务中。

Broadband printed antennas with reflector elements for millimeter-wave wireless applications

The paper presents a MM-wave broadband printed antenna array with reduced back radiation. The sectoral coverage antenna consists of eight ASP elements to give broadband impedance and radiation performance as well as eight reflector elements to improve the front-to-back ratio. The reflector elements can be readily designed despite the limited materials available at MM-wave frequencies due to the many degrees of freedom apparent in these elements. The new array had a measured front-to-back ratio of greater than 30 dB across the entire Ka-band. As a result of the broadband nature of this antenna, it can be incorporated into a multitude of MM-wave radio services.
