摘要

介绍了一种利用射频光电探测器将光功率转换为微波功率驱动的微加工cpw馈电槽天线阵列的特性。CPW线连接到光电探测器的有源表面，微波功率从有源表面传播到辐射槽。光电探测器通过一根光纤从下方输入。光电探测器输出的微波频率在15ghz - 30ghz范围内。分析使用IE3D(R)进行。得到了单天线单元和四天线单元阵列的散射参数和辐射方向图。结果表明，该天线具有良好的带宽和辐射特性。

Optically driven CPW-fed slot antenna for wireless communications

The characteristics of a micromachined CPW-fed slot antenna array driven by converting optical power into microwave power using RF photodetectors are presented. The CPW line is connected to the active surface of the photodetector, from which the microwave power propagates to feed the radiating slot. The photodetector is fed via an optical fiber from beneath. The output microwave frequency from the photodetector is in the range 15 GHz-30 GHz. The analysis is performed using IE3D(R). The scattering parameters and radiation patterns are obtained for one antenna element and for a four-element antenna array. The results show a very good bandwidth and radiation characteristics of this antenna.
