The invention discloses a novel leaky cable for an Internet of things application. The novel leaky cable comprises an inner conductor, a dielectric layer, an outer conductor, an insulating protective layer which are orderly arranged from an inner layer to an outer layer. The outer conductor is provided with continuous slots along an axial direction, and two sides of the continuous slots are provided with periodic slots. The continuous slots are wavy bend slots or straight line type slots, and the periodic slots at two sides of the continuous slots are mutually staggered. The periodic slots are single triangular slots or combined slots of multiple triangular slots, and the periodic slots are L-shaped or U-shaped slots. The novel leaky cable is suitable for an Internet of things RFID sensing application and has high coupling loss. As an ultra-high frequency (UHF) networking antenna, the high coupling loss leaky coaxial cable has the advantages that large radiation energy can be provided, and thus a label is remotely activated to achieve the purpose of reading.
