This work comprehensively investigates the design and analysis of one-port multilayer surface acoustic wave (SAW) resonators, focusing on their application in communication systems. The motivation behind this work stems from the increasing demand for high-performance communication systems with minimal signal loss. Return loss, a key parameter in evaluating signal integrity, directly impacts the efficiency and reliability of communication systems. The methodology involves a systematic design process, starting with selecting suitable materials for the multilayer structure based on their acoustic properties and compatibility with communication frequencies. The finite element simulation tool is utilized to model and simulate the SAW resonator's behaviour, allowing for precise optimization of design parameters such as layer thickness, electrode configuration, and interdigital transducer (IDT) design. Various performance metrics, including return loss, bandwidth, and quality factor, are evaluated to assess the effectiveness of the resonator in minimizing signal reflections. The results show significant improvements in return loss reduction, demonstrating the effectiveness of the proposed design approach. This work optimised the height of the electrode and found the insertion loss of the proposed device, which was-27dB. The proposed device demonstrates enhanced performance characteristics suitable for various communication system applications, including wireless networks, radar systems, and satellite communications.
