In this study, a true three‐dimensional dot‐shaped beamforming, in which the transmitted energy in a spatial region (azimuth, elevation, and range) is focused is performed with the nonuniform time‐modulated concentric circular frequency diverse array (NUTM‐CCFDA). The CCFDA structure with a radially...
