The results of the analysis of the printed 8-beam antenna array with an operating frequency of 2.2 GHz are presented. Charting devices made on the basis of the Butler matrix are widely used in modern telecommunication and radar systems and complexes. Forming in space a fan of independent radiation patterns, such arrays provide both scanning in azimuth and elevation and switching several transmitters to different directions. This ensures a high efficiency of a multipath planar phased antenna array, and reduces its overall dimensions. To test the features of the implementation of the 8-input Butler matrix, an eight-beam dipole phased array antenna was modeled. The results of the system analysis and computer simulation showed that it is possible to print the antenna with acceptable performance.
