An antenna system comprising at least two antenna modules having a certain common frequency band of electromagnetic radiation, wherein: each two locally adjacent antenna modules of said at least two antenna modules comprise a magnetic dipole, MD, antenna module and an electric dipole, ED, antenna module, having substantially mutually orthogonal polarizations of radiation; said MD and ED antenna modules (MDA,EDA) are adapted to provide respective toroidal EM radiation patterns (RP2, RP1); said MD and ED antenna modules (MDA,EDA) are collinearly arranged along a common axis such that the respective toroidal EM radiation patterns (RP2, RP1) are coaxial with respect to said common axis providing a low gain along said axis; the antenna system is characterized in that said MD and ED antenna modules (MDA, EDA) are spaced apart from one another along said axis by a distance of at least a few nominal wavelengths (λ) corresponding to said frequency band, thereby suppressing EM coupling between the antenna modules (MDA, EDA) in said common frequency band (λ); and wherein the antenna system comprises signal feeding modules (112, 122) for connecting said antenna modules to a transceiver, whereby a signal feeding module of said signal feeding modules, which is associated with a certain antenna module of said MD and ED antenna modules, includes a transmission line passing through another antenna module of the MD and ED antenna modules (MDA, EDA), near a central symmetry axis of the another antenna module where a gain of said another antenna module is relatively small, thereby reducing undesired signals induced on said transmission line by said another antenna module. each two locally adjacent antenna modules of said at least two antenna modules comprise a magnetic dipole, MD, antenna module and an electric dipole, ED, antenna module, having substantially mutually orthogonal polarizations of radiation; said MD and ED antenna modules (MDA,EDA) are adapted to provide respective toroidal EM radiation patterns (RP2, RP1); said MD and ED antenna modules (MDA,EDA) are collinearly arranged along a common axis such that the respective toroidal EM radiation patterns (RP2, RP1) are coaxial with respect to said common axis providing a low gain along said axis; the antenna system is characterized in that said MD and ED antenna modules (MDA, EDA) are spaced apart from one another along said axis by a distance of at least a few nominal wavelengths (λ) corresponding to said frequency band, thereby suppressing EM coupling between the antenna modules (MDA, EDA) in said common frequency band (λ); and wherein the antenna system comprises signal feeding modules (112, 122) for connecting said antenna modules to a transceiver, whereby a signal feeding module of said signal feeding modules, which is associated with a certain antenna module of said MD and ED antenna modules, includes a transmission line passing through another antenna module of the MD and ED antenna modules (MDA, EDA), near a central symmetry axis of the another antenna module where a gain of said another antenna module is relatively small, thereby reducing undesired signals induced on said transmission line by said another antenna module.
