Abstract

A composite cable (4) houses a plurality of leaky coaxial cables (2a, 2b) having mutually different radiation characteristics. The leaky coaxial cable (2a, 2b) includes therein an inner conductor (200) and an outer conductor (204), and has a plurality of leakage slots. The plurality of leakage slots have different slot periods relative to the axial direction or arranged in different slot patterns. The digital wireless communication device (1000) feeds a high-frequency signal from an end of the composite cable (4) and performs MIMO (multiple-input multiple output) communication.
