Enhanced bandwidth 4×4 antenna array consisting of E-shaped elements

Regarding the increasing demand for bandwidth, as well as the need for reliable communications in terms of gain and polarization, an antenna array consisting of 16 E-shaped elements is proposed. The frequency band, in which the array operates, is allocated for aeronautical and maritime radio-navigation, radiolocation, satellite-conducted earth exploration and fixed satellite communications, namely from 9 to 11 GHz.
