Abstract :
We report retrodirection using quasi-optical diode grid arrays operating at 4 GHz. Phase conjugation is achieved through a process analogous to four-wave mixing. Antiparallel diode pairs provide the third-order nonlinearity. We report retrodirection of beams with incidence angles of up to 60/spl deg/ in both the E-plane and the H-plane. Measured antenna patterns are consistent with theoretical predictions.
