Studying the microwave and decimetric emissions of solar flares the authors have found drifting microwave fine structures in the range 3100 - 5205 MHz, clearly different from millisecond spikes. Their half power duration is between 25 and 200 ms. The bandwidth is usually greater than 150 MHz, and they are slightly circularly polarized. A comparison of these microwave structures with decimetric blips (Benz et al., 1983) and with metric type III bursts shows the similarity between these three phenomena concerning frequency drift, time scale, bandwidth and polarization. The authors therefore believe that the drifting microwave bursts are also signatures of travelling electron beams. Several emission mechanisms are possible. However, the observed similarities suggest a common process for the new microwave phenomena, decimetric blips and type III bursts. The most favourable mechanism then is harmonic plasma radiation.
