Radiochannel with curved antenna utilizing three-dimensional excitation

An antenna array is considered, in the structure of which enters a linear primary element (PE) with a sector theta (sub L) for excitation of M receiving-transmitting modules, arranged equidistantly on a segment of a circle with a radius R. (A diagram of the antenna is presented). The angular position of the i-th of them with reference to the optical axis of the system is determined as theta (sub i) = alpha (sub i) theta (sub L0, where alpha (sub i) = (2(sub i)-M-1)/2(m-1); i = 1,...,M; theta (sub L) = 2 arcsin (L/2R); L - an aperture of the antenna. The path difference delta (sub R) from the center and outer modules to the center of the PE exceeds the spatial correlation interval of the signal.
