ABSTRACT

The problem of synthesizing the optimized equi-amplitude array antenna (AA) on the 8×8 grid based on a Hadamard difference set is considered. By using newly found sets of this type on the 8×8 grid the 28- and 36-element AAs having a low sidelobe level are obtained.
A numerical experiment showed that by a small alteration of the structure of such a set, further reduction of the AA sidelobe radiation is possible.
