There has been a shift from omnidirectional antennas in the azimuth plane to active phased antenna arrays with wide-angle scanning in ground communication systems. The report presents models of such antenna arrays and demonstrates the possibility of increasing the energy potential by using spatial schemes for constructing such antennas. To practically implement spatial antenna arrays, omnidirectional emitters in the azimuthal plane are used: balanced and unbalanced unipoles. It is advisable to manufacture vibrators using printed technology. The report presents the design of a micro-strip vibrator emitter for a cylindrical or concentric cylindrical antenna array. The results of numerical electrodynamic modeling are presented. The parameters and main characteristics of the emitter in the antenna array are determined.
