Summary:A D-dot micro-sensor for differential signals induced by electromagnetic pulses is provided. The sensor includes a elliptical curved electrode installed on a dielectric layer with a high dielectric constant. A ground layer electrode is attached to the back of the dielectric layer. Signals generated on the two electrodes pass through an impedance matching transmission line and are output by an SMA terminal. By means such as increasing the dielectric constant of the dielectric layer, optimizing the effective area of the curved electrode, and impedance matching of the transmission line, the sensitivity and the measurement bandwidth of the sensor are improved.
