针对无源毫米波成像系统，提出了一种简单的射频模块结构。本文报道了该模块的探测器设计结果。探测器平面电路和波导喇叭天线通过宽带微带到波导的过渡连接。许多天线被安排在镜头的焦点周围，这就形成了所提出的射频模块。由于该模块是由基板和加工过的平面金属板组成的层状结构，因此易于制造。在这里，详细描述了所提出的成像模块的结构。接下来，描述了所提出的成像模块中使用的探测器设计的结果。
Simple configuration of RF module is proposed for passive millimeter-wave imaging system. The results of the detector design for the module are reported in this paper. A detector planar circuit and a waveguide horn antenna are connected by broadband microstrip-to-waveguide transition. A number of the antenna is arranged around the focal point of the lens, which results in the proposed RF module. Since the module forms a layer structure composed of substrate and machined flat metal plates, which contributes low-profile and easy manufacturing. Here, the structure of the proposed imaging module is described in detail. Next, the results of the detector design used in the proposed imaging module are described.
