Abstract
The design of an active leaky-wave antenna which integrates the antenna with a feedback synthesizer is introduced. The measurement result shows that the antenna has very low back lobe radiation compared with that of traditional single-terminal feeding leaky-wave antennas. Single frequency measurement shows that the radiated power difference between the main beam and back lobe is >15 dB at 8.2 GHz. For the designed feedback synthesizer antenna, the measured radiated power difference between the main beam and back lobe is >15 dB at 9.25 GHz, and the scanning angle is ~5° as the synthesizer frequency sweeps from 9.25 to 9.37 GHz
