摘要

提出了一种极化纯度大于28 dB、75.7 GHz辐射功率为8 dBm的集成有源天线。线极化辐射器由平面谐振天线和单片集成在硅衬底上的透射时二极管组成。这种有源天线在低成本多通道传感器系统中有各种应用，例如用于目标分类。讨论了设计准则。制备的SIMMWIC器件的特性包括输出功率、偏振纯度和远场方向图的测量。此外，采用次谐波注入锁紧技术成功地稳定了器件的振荡频率。对锁定振荡器的调频噪声特性进行了表征。给出了实测结果，并与理论计算结果进行了比较。

A SIMMWIC 76 GHz front-end with high polarization purity

An integrated active antenna with a polarization purity better than 28 dB and a radiated power of 8 dBm at 75.7 GHz is presented. The linearly polarized radiator consists of a planar resonant antenna and a transit-time diode monolithically integrated on a silicon substrate. This active antenna finds various applications in low-cost multi-channel sensor systems, e.g. for object classification. Guidelines for the design are discussed. The characterization of the fabricated SIMMWIC devices includes measurements of output power, polarization purity, and far-field pattern. Moreover, the oscillation frequency of the devices has been successfully stabilized using subharmonic injection locking. The FM noise behavior of the locked oscillator has been characterized. The measured results are presented and compared to theoretical calculations.
