Abstract
An ${S}$ -/ ${K}$ -band metasurface-based antenna with a shared aperture is proposed for 5G applications. The metasurface is designed with the dual-band characteristics for two antennas to work in the same aperture without interference. Based on the characteristic mode analysis, $3\times 3$ metasurfaces are proposed for the ${S}$ -band radiation. To radiate the ${K}$ -band electromagnetic wave without blocking, the metasurfaces are discretized by the subcell of a square ring and an inner square patch to achieve a frequency selective function. Then, as an example, the microstrip-fed slot is used to drive the metasurfaces at the ${S}$ -band, while an $8\times 8$ substrate integrated waveguide slot array antenna between microstrip and metasurface is designed at the ${K}$ -band. The measurement shows the 10 dB return loss bandwidths of 23.45% and 4.8% and the realized gain of 7.52–10.88 and 21.3–22.4 dBi over the ${S}$ -band (3.2–4.05 GHz) and the ${K}$ -band (25.22–26.46 GHz), respectively.
