Abstract: Proceeding from the sensitivity improvement,the relation between the electrode length and the sensitivity/bandwidth of no-electrode electrical field sensor is analyzed. By comparing the transmission function of different structures and verifying the feasibility of balanced detection scheme, the 3-port structure using balanced detection is chosen for the coming generation sensors.
