摘要： A tank arrangement including a guided wave radar level gauge installed in a tank, and having a single wire transmission line probe extending through a passage through a conducting structure in the tank. Along the section of the probe that extends through the passage, the arrangement comprises a propagation field limiting structure adapted to reduce a propagation field of an electromagnetic signal propagating along the probe. With this design, the radial extension of the propagating field can be locally reduced so that a sufficient portion of the signal power is allowed to pass through the passage.

摘要： An antenna device is disclosed, including a control means and at least two transmission means in predeterminable positions and at least two receiving means in predeterminable positions. The control means is set up in such a way that it alternately individually excites the at least two transmission means in transmission, in such a way that each of the at least two receiving means receives a transmitted signal generated by each of the at least two transmission means. The control means is further set up to excite the at least two transmission means jointly in transmission at a predeterminable moment in such a way that each of the at least two receiving means receives a transmission signal generated by a single virtual transmission means.
