“…In this connection, microstrip dipoles are of interest due to relative simplicity of their manufacturing and compatibility with semiconductor devices [3]. The earlier studies performed by the authors of this paper in [4,5] showed that an oscillator in the form of a planar log-periodic antenna with Gunn diode or field-effect transistor built into its arms is effective in a wide range of frequencies. Low (about 1%) oscillation efficiency and limited tunability are deficiencies in the case of a Gunn diode.…”

We experimentally study microwave oscillations in a hybrid integrated circuit comprising a fieldeffect transistor and a log-periodic microstrip antenna on a dielectric substrate. The oscillations were observed both at the main resonance frequency of the antenna and at harmonics in a range of 6 to 40 GHz. The opportunities for oscillator design optimization were studied in application to the millimeter-wave range.
