Ridged waveguide antenna submerged in dielectric liquid

摘要

A system for remote microwave interrogation and imaging of biological targets comprises at least one microwave, double ridged waveguide antenna probe which operates at S-band frequencies, and a high dielectric liquid medium, preferably water, in which both the probe and the target are completely immersed. For imaging applications, the probe is positioned with respect to the target such that the target is in the near field of the antenna.
