The analysis of the insulated dipole in a relatively dense medium is extended to coupled, individually insulated elements arranged in a circular array. It is shown that the transmission‐line‐like distributions of current are preserved for each phase sequence but with different complex wave numbers that depend not only on the electrical properties of the insulating and ambient media but also on the coupling among the elements. Special attention is given the two‐element and three‐element arrays.
