| description | A novel customized <inline-formula> <tex-math notation="LaTeX">$\pi $ </tex-math></inline-formula>-shaped split-ring resonator metasurface arranged in two configurations is presented to decouple <inline-formula> <tex-math notation="LaTeX">$1\times 2$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$1\times 4$ </tex-math></inline-formula> Millimeter-Wave (MMW) Magneto-Electric (ME) Dipole in the H-Plane with 1.6 mm (<inline-formula> <tex-math notation="LaTeX">$0.32\lambda $ </tex-math></inline-formula> at 60 GHz) inter-element spacing. The metamaterial unit cell is first designed to inhibit the propagation of coupled surface waves within the bandwidth of interest. A <inline-formula> <tex-math notation="LaTeX">$5\times 2$ </tex-math></inline-formula> arrangement of this unit cell is carefully positioned on the top and bottom of the superstrate with 1 mm spacing (<inline-formula> <tex-math notation="LaTeX">$0.2\lambda $ </tex-math></inline-formula> at 60 GHz) between the antenna and the superstrate. In the <inline-formula> <tex-math notation="LaTeX">$1\times 2$ </tex-math></inline-formula> array, a maximum measured mutual coupling reduction of 53 dB is observed within the 52–66 GHz bandwidth (23.7%). To further demonstrate the uniqueness of the metasurface, an <inline-formula> <tex-math notation="LaTeX">$11\times 2$ </tex-math></inline-formula> configuration of this unit cell is arranged as a superstrate for the <inline-formula> <tex-math notation="LaTeX">$1\times 4$ </tex-math></inline-formula> ME-dipoles. A maximum measured mutual coupling reduction of 40 dB is achieved without a considerable effect on the radiation characteristics. Parametric analysis is performed to confirm the uniqueness of this new decoupling structure. The proposed antenna exhibits measured high total efficiency (>89%), high gain (>8 dB), low envelope correlation coefficient (<inline-formula> <tex-math notation="LaTeX">$ < 0.0003$ </tex-math></inline-formula>), and very good radiation characteristics throughout the entire bandwidth. The fabricated prototype antenna is measured to validate the simulation results. The proposed antenna is a good recommendation for V-band millimeter-wave MIMO applications like radar research. |
