Study of double-side Thru calibration kit by non-contact coupling structure

In order to apply the non-contact coupling technology on double side measurement calibration, we design a high-efficient loop structure. The signal between two coils is transmitted by coupling. The reliable model is established in the paper, so we can get loss and radiation of coupling loop. The linearity and return loss are improved by the novel structure proposed in the study. By this paper, the calibration Thru kit applied by non-contact technology will be completed in the near future.
