In the present work, the possibility of developing a pattern-forming circuit for an ultra-wideband multibeam antenna array is studied. Results of investigations of separate elements of the pattern-forming circuit are presented. Brief analytical calculation of an ultra-wideband directional coupler is presented together with calculation procedure and characteristics of the pattern-forming circuit for a four-beam antenna array. Results of calculations and measurements of the characteristics of the directional coupler are presented. A variant of the topology of the pattern-forming circuit is suggested.
