Abstract :
An active phased array using unilateral injection-locked oscillators was developed. The phase shift is controlled by electronic tuning and the beam scanning is demonstrated. Amplifiers inserted between oscillators eliminate reverse injection locking and control the locking bandwidth. Both theory and experimental results are presented and discussed.<>
