This paper summarizes the results of investigations, conducted by authors on the so called "active microwave antennas" -the structures, in which microstrip antenna is connected with active semiconductor element without intermediate feeder. The most attention is focused to the processes of microwave generation, particularly in the active antenna array. Active antenna, in this case antenna-oscillator (AO), looks as a planar log-periodic antenna, integrated with field-effect transistor at the diele
