摘要

这项工作说明了一个负电阻振荡器在微波状态下被用作非接触式传感装置。该振荡器在3.992 GHz产生−0.28 dBm的输出功率，用作近场监测设备。一个4×6马赛克图案的介电板(每2cm × 2cm)填充了各种介电常数值，范围从2.2 - 12.85。±50 kHz分辨率在识别板的介电常数在每一行和列确保可重复的响应时，传感器是5mm的测试表面。

A 4 GHz Near-Field Monitoring Planar Oscillator Sensor

This work illustrates a negative resistance-based oscillator in microwave regime that is used as a non-contact sensing apparatus. The oscillator generates −0.28 dBm output power at 3.992 GHz that is used as a near-field monitoring device. A 4×6 mosaic pattern of dielectric slabs (2cm × 2cm each) is filled with various permittivity values ranging from 2.2 – 12.85. ±50 kHz resolution in recognizing the dielectric constant of the slabs in each row and column ensures a repeatable response when the sensor is 5mm away from the test surface.
