| Popis: | A Si on-chip bow-tie antenna array was developed for transmitting Gaussian monocycle pulses (GMPs) whose center frequency was 15 GHz. The length and flare angle of the bow-tie antenna were 7.16 mm and 53°, respectively. GMPs were emitted from the antenna to the substrate whose dielectric constant was 7 and reflected at the target whose dielectric constant was 30. A minimum dielectric target size of 3×3 mm2 at a depth of 20 mm in the dielectric substrate was detected and a two-dimensional cross-sectional image of a dielectric target in a dielectric substrate was reconstructed by confocal imaging algorithm. |
