ABSTRACT
In this study, an acoustic leaky-wave antenna (LWA) with heterogeneous structure is proposed and the functions of the spatial directional radiation and acoustic source localization are achieved via utilizing the presented antenna configuration. In the radiating mode, the designed antenna possesses peculiar frequency-scanning characteristics, which enable it to determine the directional radiation of sound waves with diverse incident frequencies. Considering the receiving mode, the antenna emerges with explicit directional frequency characteristics, which ensure its function of spatial acoustic source localization. Additionally, compared with the traditional acoustic LWA, the proposed antenna structure exhibits sharper directivity and has potential applications in high-precision acoustic source localization.
