We have measured the ac Josephson effect in small-area superconducting tunnel junctions at 604 GHz (lambda = 496 ..mu..m) using a resonant planar dipole antenna to couple the radiation into the junction. In a 176-..cap omega.. junction, we have observed up to the 7th Josephson step (at 8.75 mV), a performance comparable to that seen in point contacts. We also compare our data with the results of the RSJ model and of the Werthamer theory.
