Abstract

A near-field millimeter-wave imaging technique is introduced which is capable of producing images with sub-wavelength resolution. A phantom made of a Teflon board containing samples of different materials with dielectric constants ranging from 1 to 48 was built, and a near-field loop antenna and a 110GHz vector network analyzer were used to capture near-field images of the Teflon board. A novel image processing method is described that is capable of achieving an image resolution of 0.5mm at 110GHz.
