In this study, a novel design of tunable metasurface (MS) is proposed and demonstrated. The MS can realise multiple functions, such as radiation and scattering manipulation. To design MS unit, four varactor diodes are used so that resonant and in‐phase reflection band can be tuned through adjusting diode bias voltage. For the whole MS array, feeding structures are added to realise radiation performance. Meanwhile, adjusting reflection phase of different units can achieve low scattering performance. Measured results agree well with simulations, verifying the validity of the proposed design. This work offers us an effective strategy to design multi‐functional tunable MS and other related practical applications.
