A wideband surface‐scanning near‐field sensor in the form of a slot antenna, remotely interrogated by a wireless signal is reported. Perturbation of the antenna near‐field by subwavelength objects ( λ /10) on the surface is detected in the far‐field as a change in the antenna signature, yielding image of the surface structure. © 2016 Wiley Periodicals, Inc.
