摘要Initial design of phase-frequency scanned array using composite right/left-handed (CRLH) waveguide leaky-wave antennas (LWAs) is studied in this paper. The array consists of 32 frequency scanning CRLH LWAs that are fed by a phased feed system. Two-dimensional (2D) beam steering capability is achieved in the plane normal to the array aperture and verified by the full-wave simulations. This array is capable of scanning to 61 degrees from backward to forward directions in the frequency-scan plane and 17 degrees in the phase-scan plane. The beamwidth is approximately 2 degrees with -20 dB sidelobe level (SLL) in the frequency-scan plane and 2.5 degrees with maximum -10 dB SLL in the phase-scan plane. Compared with traditional 2D scanning array, the feed system of this phase-frequency scanned array can be simplified significantly.
