The representation of the source of the electromagnetic fields for a thin‐walled tubular transmitting antenna is examined. Application of a standard formula for the electromagnetic field leads to the concept of a magnetic current source. With this type of source, the correct integral equation for the tubular antenna is easily derived because the standard vector potential method (with an extra term for the potential due to the magnetic current) can be used. The method is easily applied to other excitation geometries.
