- Abstract
- This letter presents a novel reflecto-directive system using a composite right/left-handed (CRLH) leaky-wave (LW) antenna and heterodyne mixing. The system receives a signal at a fixed frequency with a patch antenna and reflects it back toward any desired angle by tuning the LO frequency of a mixer. The performances of the system are demonstrated experimentally: 5 GHz incoming signals at -30degrees, 0degrees and +30degrees are detected and transmitted, or "reflected", to -20degrees at 3.5 GHz, +20degrees at 4.5. GHz and +50degrees at 5.5 GHz in agreement with the angle-frequency relationship of the CRLH antenna.
