提出了一种小型、高响应的毫米波平面肖特基探测器，用于单平面和低成本制造。为了实现最佳功率传输，零偏置肖特基二极管通过天线设计本身进行阻抗匹配，具有已建立的曲折偶极子和新的折叠偶极子类型。特别是，高达200 GHz，折叠偶极子表现出一个单一的响应峰值，特别有利于通信。实现的探测器表现出出色的系统射频电压响应度高达16005 mV/mW，在87.8 GHz的无透镜或前置放大器。此外，具有0.39 pW/root Hz的检测器证明了优异的NEP水平。
Compact and highly responsive millimeter wave planar Schottky detectors are proposed for uni-planar and low-cost fabrication. For optimum power transfer, the zero-bias Schottky diodes are impedance matched by the antenna design itself, with an established meander dipole and a new folded dipole type. In particular, up to 200 GHz, the folded dipole exhibits a single responsivity peak, notably beneficial for communications. The realized detectors exhibit an outstanding system RF voltage responsivity of up to 16005mV/mW at 87.8 GHz without lenses or pre amplification. In addition, an excellent NEP level is demonstrated by the detectors with 0.39 pW/root Hz.
