Abstract: | Problems of the design of a centimeter-band antenna array containing a multichannel power divider based on EBG waveguides and helical radiators are considered. The general configuration of such an array is proposed. The properties of this array and the requirements on the array elements are analyzed. Features of the design of two-channel and four-channel elementary power dividers forming the multichannel power divider are studied. The structure and the parameters of these devices are determined. The array input part is designed in the form of a coaxial-to-waveguide transition (CWT) with equal power division. The CWT characteristics obtained with the use of numerical simulation are compared with experimental data. The results of the experimental investigation of a 16-element thinned antenna array in the frequency band 8–10 GHz are presented. |
