Laminated capacitance transmission coupler

The invention discloses a laminated capacitor transmission coupler, and the coupler comprises a coupler transmitting end which comprises a first polar plate and a second polar plate which are laminated with each other and are arranged at an interval; the coupler receiving end comprises a fourth polar plate and a third polar plate which are mutually laminated and arranged at an interval; filling dielectric media are arranged between the first polar plate and the second polar plate and between the fourth polar plate and the third polar plate; electric energy transmission between the coupler transmitting end and the coupler receiving end is achieved through a transmission medium, and the relative dielectric constant of the filling dielectric is smaller than that of the transmission medium. The stacked capacitive coupler can solve the problem that an existing stacked capacitive coupler is low in transmission efficiency due to the fact that polar plates on the same side are close to each other and the formed equiv
