In modern terrestrial communication systems, there is now a shift from aperture antennas to wideband antenna arrays with wideangle scanning. Such antenna systems can be implemented in the form of conformal or spatial active phased antenna arrays (APAA). At the same time, spatial antenna arrays have better energy and cost characteristics than conformal ones. The energy characteristics of conformal and spatial antenna systems have been calculated, which show that for antennas with a small equivalent aperture (of the order of 1,5–2 wavelengths) difference in directional coefficient (directivity) is 1 dB, but with an increase in the diameter of the antennas, it also proportionally increases. However, to build spatial antenna arrays with wide-angle scanning, non-directional emitters in the azimuthal plane are needed. The article presents the results of modeling microstrip vibrator emitters, providing allowable change in directivity and matching characteristics in the 9% band
