For dielectric investigations of tissue in the VHF frequency range we propose an open-ended probe separated from the investigated material with non-conducting foil. The influence of the foil on the dielectric response of the probe was studied using reference materials and the model explaining the observed properties was presented and tested. Using the probe we tested the dielectric properties of samples obtained from 113 patients treated surgically against breast cancer. We found that in 94% of investigated cases the dielectric assignment was consistent with the histological one. High efficiency in the differentiation between normal and neoplasm breast tissues and the capacity to satisfy aseptic conditions are promising in intra-operative cancer diagnostics.
