Distributed oscillator based on Composite Right-/Left-Handed unit cells

A circuit topology for a fixed frequency oscillator based on Composite-/Right-/Left-Handed distributed amplifier is proposed. For this topology, it is demonstrated that each transistor contributes equally to the output power. The oscillation condition is introduced, too. The oscillator has been designed and fabricated for a frequency of oscillation equal to 2.8GHz. The experimental and simulated results are in good agreement.
