Abstract (en)

A method of feeding an antenna array, wherein the pattern similar to the cosecant pattern is achieved, according to the invention, characterized in that the consecutive radiators (RAD) are fed alternately with a positive and negative phase difference (F2-F1, F3-F2, F4-F3,..., FN-FN-1). Additionally, at least once two adjacent phase differences (from a set of F2-F1, F3-F2, F4-F3,..., FN-FN-1) at least once have the same direction of change, all the phases (F1, F2, F3, F4, ..., FN) being normalized to a range from 0° to 360°. An antenna array feeding arrangement, comprising an array of radiators, according to the invention, characterized in that it comprises at least 8 radiators (RAD). Consecutive radiators (RAD) are fed alternately with a positive and negative phase difference (F2-F1, F3-F2, F4-F3,..., FN-FN-1) and at least two adjacent phase differences (from a set of F2-F1, F3-F2, F4-F3,..., FN-FN-1) at least once have the same direction of change, all the phases (F1, F2, F3, F4, ..., FN) being normalized to a range from 0° to 360°.
