The results of research on the layout of the antenna array for a promising cellular base station in the frequency range 1,81,88 GHz, which includes a linear antenna array of 12 slotted elements with rectangular directors, the diagram forming scheme of which uses a modification of the Rotman lens, characterized in that for the sake of reducing its overall dimensions, the lens is folded in half the earth is located in the center, and on both sides of it-the halves of the lens body with exponential strip transformers. It is shown that to reduce the level of the side lobes of the antenna system in the reception mode, interpolation and extrapolation antenna arrays can be used. An extrapolation array can also be formed in order to increase the directional coefficient of the receiving antenna system and resolve radio sources that are not resolved by the real antenna array.
