Abstract: A multi-directional radiation leaky coaxial cable is disclosed, including an inner conductor, an insulating layer, an outer conductor and a sheath which are sequentially and coaxially nested from inside to outside. The outer conductor is provided with at least two rows of slotted hole groups, the at least two rows of slotted hole groups are distributed at different angles in a circumferential direction of the outer conductor, each row of slotted hole group includes a plurality of slotted hole arrays which are periodically arranged along an axial direction of the outer conductor, each slotted hole array includes a plurality of slotted holes, pitches of the slotted hole groups are the same, and a periodic arrangement difference of two adjacent rows of slotted hole groups in the circumferential direction is half a pitch, so that a phase difference of respective excitation electric fields is 180°. According to the leaky coaxial cable, multiple rows of slotted hole groups are arranged, a phase difference of two adjacent rows of slotted hole groups in the circumferential direction is half a pitch, and the phase difference of the excitation electric fields is 180°, so that source separation can be achieved in space, and excitation sources are independent and do not interfere with each other, thus increasing a number of radiation directions of all frequency points in an operating frequency band of the leaky coaxial cable, and making the leaky coaxial cable have a higher application scene applicability.
