摘要

We propose a novel power recycling scheme for distributed amplifiers (DAs) integrated with composite-right/left handed transmission line leaky wave antennas (LWAs). This new type of power recycling scheme is essentially inspired by a ring-resonator. By forming a closed-loop on the drain side LWA of the DA, we create the ring-resonator that is actively coupled by the DA from the gate line and hence can obtain a substantial gain enhancement compared to the one directly terminated without the loop. Such enhancement fluctuates with respect to the frequency. At the resonant frequencies of the closed-loop ring-resonator, the enhancement reaches a maximum. The phenomenon will be explained and derived theoretically in detail, and then validated through the real implementation.
