Effects of element pattern on the performance of a rectangular array

The radiating or receiving characteristics of array elements are changed from that of isolated elements due to the mutual coupling effects and the array performance becomes different from that originally designed by assuming isolated elements. In the present work, the effects of element pattern on the performance of a rectangular array with triangular geometry of dipoles above a ground plane are investigated. The concept of element gain function is used to examine the array performance in terms of mainbeam width and sidelobe level with respect to uniformly spaced and space-tapered arrays.<
