This paper examines the possibility of an electromagnetic interference (EMI) caused by unintentional radiated emissions from an unshielded twisted pair (UTP) cable in the sub-6GHz band of 5G. First, it is experimentally and numerically confirmed that a UTP cable with a twist pitch of 20mm and a sheath with relative permittivity of 2.9 radiates above 5.7GHz. It is also clarified that the radiated emissions are attributable to the twist structure. In addition, the usefulness of two equations, derived in developing radiating pair cables, to easily calculate the radiation band and the radiation angle to solve the EMI problem is validated.
