Abstract: The present disclosure provides a wide beam radiation leakage coaxial cable, which includes an inner conductor, an insulating layer, an outer conductor and a sheath coaxially nested from inside to outside in sequence, at least two columns of slot groups are provided on the outer conductor, the columns of slot groups are distributed at different angles in the circumferential direction of the outer conductor, the included angle between two adjacent columns of slot groups is ?=?/n, where ? is the target radiation width, n is the number of columns of slot groups, each column of slot groups includes a plurality of slot arrays periodically arranged in the axial direction of the outer conductor, the pitch of each column of slot groups is the same, the pitch phase of each column of slot groups on the same leakage cable section is consistent, and each slot array includes a plurality of slots.

Abstract: A low-frequency filtering unit includes a vibrator arm, a balun base, a balun feeder line and a balun chamber tube for arranging the balun feeder line; the vibrator arm includes two radiation arms, one end of the radiation arm is vertically connected to one end of the other radiation arm to form an integral L-shaped right-angle structure, the balun chamber tube is arranged at the connection between the two radiation arms, and the wave-trap structures on the transverse radiation arm and the longitudinal radiation arm are symmetrically arranged with a 45° angular bisector of the L-shaped right-angle structure as a center line; the low-frequency filtering unit is provided with four vibrator arms which are symmetrically arranged in pairs around the periphery of the balun base along a diagonal line and form an integral cross orthogonal structure, and the vibrator arms.
