The problems of synthesis of radiating systems for antenna-feeder devices of linear stations of mobile radio communication are con-sidered. The variants of construction of such antenna-feeder devices on the basis of multifrequency ring antenna arrays (RAA) are considered, as the radiators for which log-periodic antennas (LPA) are used. The results of modeling various variants of constructing such ring antenna arrays are presented.
As the first variant, a RAA with rotational symmetry, containing radiators uniformly located on a cylindrical support with a height shift, was considered. At the same time, low-frequency (900 MHz) and high-frequency (1800 MHz) LPA were used as emitters. As a second option, a single-ring RAA based on the LPA, calculated for the entire frequency range of 890−1880 MHz, was considered.
The obtained results determine the prospects of using the second variant of RAA in the organization of multi-channel communication with the possibility, including, detuning from interference.
