Abstract: The investigations have been conducted on the involved design parameters to analyze the behavior of the microwave displacement sensor output characteristics. To implement this, a dielectric resonator loaded to a reflection mode operated microstrip line circuit is proposed. For the proposed reflection mode sensor, the sensor features like resonant frequency, impedance matching position, sensitivity, and dynamic range are sensitive to the displacement of DR to microstrip line. The impact of the substrate shape and size, and resonators geometrical properties are numerically analyzed and experimentally validated by using VNA. The sensor analysis shows good matching between both HFSS simulations and VNA measurements.
