Radio frequency apparatus with interference compensation

摘要

A high-frequency (HF) appliance (1) is equipped with at least one phase-rotation member (PH) and the phase of the radiation vector of one interfering radiation source (A1) is rotated so that it is displaced in the middle of the working frequency range, preferably of the range up to approximately 300Hz, by at least 180 degrees or an aliquant multiple of this relative to the phase of the resulting radiation vector of the remaining interfering radiation sources (A2-A4).
