Generation of Patterns From Concentric Ring Arrays With Dipoles and Waveguides

Radiation patterns are produced from concentric ring arrays by using practical elements, such as dipoles and waveguides which is presented in this article. Ring arrays, which produces high sidelobes, create electromagnetic interference (EMI) problems. To overcome this problem, analysis and synthesis is carried out and generates the directional patterns of concentric ring arrays using practical radiators. The directivity is observed for concentric dipole ring arrays and concentric waveguide ring arrays is 72.21 dB. The comparative data is presented in the result.
