In this paper, a linear transducer array based on type 1-1-3 piezoelectric composite material is designed, and the admittance characteristics of the array are analyzed by finite element method. Using the finite element analysis method, the conductivity curve of linear transducer array based on type 1-1-3 piezoelectric composite material and type 1-3 piezoelectric composite material and the influence of array position on the conductivity curve were compared and analyzed. To further verify the simulation results, a “one-piece forming” transducer array preparation process is designed and experimental samples are prepared. The experimental results show that the receiving sensitivity consistency of the 1-1-3 linear transducer array is 4 dB higher than that of the 1-3 linear transducers, and the consistency of the transmission voltage response is stable within 0.6 dB, which effectively improves the array consistency of the high-frequency transducer array.
