摘要： A device for transmitting and receiving signals for a radio network comprises an air interface; a MIMO antenna; and an antenna-side frequency conversion device provided between the air interface and a home distribution network. The antenna-side frequency conversion device comprises at least one frequency converter via which the receive signals obtained via the at least one polarization of the dual-polarized antenna or via at least one of the at least two antennae can be converted into an intermediate frequency range that is unused and/or free in the home distribution network. At least one receive-side frequency back-conversion device is provided between the home distribution network and a receiver. The receive-side frequency back-conversion device is configured in such a way that a frequency back-conversion of the frequencies converted into an unused frequency range can be fed back into the received frequency range.

摘要： An antenna for a mobile telecommunication base station has a plurality of radiating elements and at least two transmission paths or at least two receiving paths, which have different polarizations and are linked with two of the radiating elements and physically distanced from each other. The radiating elements are dielectric radiating elements. The individual radiating element interval between the radiating elements is less than 0.6λ, wherein λ is the wavelength of the center frequency of the lowest resonance frequency range of the radiating elements.
