Abstract: Integration of active device with  microstrip antenna without intermediate feeders can significantly improve the weight and size characteristics of the solid-state sources of electromagnetic radiation in the microwave range. Nonlinear dynamics of microstrip active integrated antenna in the single-frequency, multi-frequency and chaotic regimes are studied in this work. Electromagnetic chaotic oscillations with a continuous spectrum in the frequency range from 6.4 to 6.6 GHz are experimentally observed.

Key words: active antenna, antenna-oscillator, microstrip antenna, chaotic oscillations.
