A dual-band dual-beam metasurface antenna (MSA) is proposed. The prototype consists of a layer of dual-band metasurface cells and a symmetrical feeding network. The feeding network contains several coupling slots and a two-port bended microstrip line beneath the slots. The simulation shows the backward or forward radiation of the two bands can be achieved simultaneously by a common feeding network. As a result, the lower-band beam angle and gain of the MSA can be up to 47 degree and 10 dBi, respectively. Meanwhile, the higher-band beam angle and gain of MSA are up to 40 degree and 12.5 dBi. The total size of the MSA is 0.75λ0x 2.22 λ0x 0.05 λ0at 3.5 GHz. Compared with conventional dual-band dual-beam antenna arrays, the proposed MSA features low-cost, low-profile, simple and compact design, which can be expected to find potential applications in high-capacity communication system.
