Abstract. The circular antenna array of six patch antennas as an antenna system for access points with full coverage in azimuth is proposed. The array is two-polarized and operates in the 2.4 GHz band. The model is constructed and numerical calculations of frequency and radiation characteristics are carried out. It is shown that each element has the directional radiation pattern with the front-to-back ratio around 20 dB, and the entire array provides full 360° coverage in azimuth by beam forming in each of six angular sectors. Use in Wi-Fi access points is feasible.

Keywords: patch antenna, directional radiation pattern, antenna array, access point, scanning in azimuth, beam forming.
