Abstract

In this paper, intensive investigations are carried out to produce directional patterns from linear concentric ring arrays using isotropic radiators . A ring array which produces about −8 dB sidelobe level creates a lot of Electromagnetic Interference problems. To overcome this, the concentric ring arrays are used and these produce about −17.6 dB sidelobe level. However, these sidelobes are still high in some applications such as satellite communications, wireless communications, and broadband applications. Therefore, a linear concentric ring array is a concept introduced for optimization of the radiation patterns are found in. Using the new concept, the directional patterns are numerically evaluated for linear concentric ring arrays for different concentric rings. The data presented here found that the first sidelobe level is reduced by −36.33 dB, null-to-null beamwidth is decreased to 6.78 degrees, and directivity is increased to 90.72 dB.
