Device
Dual-band millimeter-wave (mmWave) metasurface with arbitrary multibeam, desired polarization including linearly/circularly polarized modes, and pattern diversity.
Spectrum
28 GHz (N257 band), 26.5 – 40 GHz (Ka band)
Novelty
The proposed design method enables the dual-band metasurface to achieve the desired radiation characteristics with a single LP excitation port to enhance the design’s integration level.
The method offers continuous phase compensation across both bands, with the functions of each band designed independently.
The method can realize the fusion design of LP and CP modes, which can effectively improve the polarization multiplexing ability for various information transmission modes.
Application
Active phased arrays employed in ship-borne and air-borne radar systems capable of high-speed beam scanning and multitarget tracking.
Performance
In the Ka band: 21.68 dBic (LHCP) and 23.92 dBic (RHCP) peak gain; 24.93% peak aperture efficiency.
