Abstract
A composite cable () houses a plurality of leaky coaxial cables having mutually different radiation characteristics. The leaky coaxial cable () includes therein an inner conductor and an outer conductor, 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 feeds a high-frequency signal from an end of the composite cable () and performs MIMO (multiple-input multiple-output) communication.
