Abstract

The far-field angular response pattern for dipole antenna-coupled infrared detectors is investigated. These devices utilize an asymmetric metal-oxide-metal diode that is capable of rectifying infrared-frequency antenna currents without applied bias. Devices are fabricated on both planar and hemispherical lens substrates. Measurements indicate that the angular response can be tailored by the thickness of the electrical isolation standoff layer on which the detector is fabricated and/or the inclusion of a ground plane. Electromagnetic simulations and analytical expressions show excellent agreement with the measured results.

摘要

研究了偶极子天线耦合红外探测器的远场角响应模式。这些器件采用了一种不对称金属氧化物金属二极管，该二极管能够在不施加偏置的情况下对红外频率的天线电流进行整流。器件在平面和半球形透镜基板上制造。测量结果表明，角响应可以通过制造探测器的电隔离间隔层的厚度和/或包含接地平面来调整。电磁模拟和解析表达式与测量结果显示出极好的一致性。
