Abstract: Embodiments of the present disclosure provide an array antenna bandwidth enhancement method based on phase regulation and control, an apparatus and an array antenna, a reflection coefficient of the array is calculated utilizing a one-time-reflection model calculation formula determined based on a small reflection theory, thus saving a full-wave simulation time of a large-scale array, and greatly improving a design efficiency. Enhancement of a bandwidth of the array using the array bandwidth enhancement method based on phase regulation and control may save a time for stepwise increased and matching adjustment of the large-scale array, and reduce design complexity. The provided method is simple and efficient, and is beneficial to realization of a wideband design of the large-scale array antenna.

Abstract: An ECG electrode is provided. The ECG electrode includes an electrode substrate and a doped graphite-like carbon film located on an outer surface of the electrode substrate. The doped graphite-like carbon film includes graphite-like carbon, and first nano-crystals and second nano-crystals that are embedded in the graphite-like carbon. The first nano-crystal includes a weak carbon-bonding element. The weak carbon-bonding element has a part that exists in a form of a metallic elementary substance. The first nano-crystal includes a columnar structure. The columnar structure extends in a thickness direction of the doped graphite-like carbon film. The second nano-crystal includes a strong carbon-bonding element. The strong carbon-bonding element bonds with the carbon element in the graphite-like carbon through a chemical bond. The second nano-crystals are distributed between adjacent and spaced columnar structures.
