Overview

Randomized trial demonstrates the sensitivity of microwave field distributions in microstrip lines, highlighting practical implications for circuit diagnostics.

Key Points

The aim is to accurately characterize microwave signal propagation and field distributions in microstrip lines to ensure circuit reliability.
Developed a near-field scanning microwave microscopy technique with beat-frequency enhancement.
Maintained constant probe–sample distance and dielectric environment during characterization.
Measured transmission coefficient S21 to visualize field strength and optimize detection sensitivity under varied signal conditions.
ΔS21 shows a positive correlation with input signal power, indicating sensitivity to input changes.
Detection sensitivity enhanced as input signal frequency nears the probe-sample coupling resonant frequency, with a minimum detectable power of -40 dBm.
Surface scanning effectively visualized microwave field strength distributions, matching simulation data for normal and defective lines.
