摘要：

Antenna arrays are used in many applications, such as space technology or long-distance communications. However, there is often an issue of large antennas' sizes for such systems. For example, such a problem is urgent in wideband arrays. This is important because then the distance between antennas in the equidistant arrays cannot be hold. Thus, the side diffraction maximums appear. Here we show that conversion to non-equidistant antenna arrays decreases radiation pattern's side lobes for direct radiation and deflection. Based on methods in the manuscript, we reduced side lobes of our array to -10dB compared to the main lobe. These methods allow calculating non-equidistant antenna arrays with high accuracy using information about antenna's characteristics. Thus, the side radiation is decreased and the antenna array efficiency is improved.
