Power-Recycling Feedback System for Maximization of Leaky-Wave Antennas' Radiation Efficiency

  title={Power-Recycling Feedback System for Maximization of Leaky-Wave Antennas' Radiation Efficiency},
  author={H. V. Nguyen and Armin Parsa and Christophe Caloz},
  journal={IEEE Transactions on Microwave Theory and Techniques},
A novel power-recycling feedback scheme is proposed for systematic maximization of the generally poor radiation efficiency of leaky-wave antennas (LWAs). In this scheme, the nonradiated power at the end of the LWA structure, instead of being lost in the terminating load, is fed back to the input of the LWA through a power-combining system, which constructively adds the input and feedback powers while ensuring perfect matching and isolation of the two signals. As a result, the radiation… CONTINUE READING
