Abstract: In order to verify the existence of the theoretically predicted, extremely sharp resonances that occur in a circular array with many identical elements but only one driven, an experimental investigation of such an array has been carried out. The circular array consists of 90 monopole elements equally spaced around a 6-meter circumference. The properties of the array are observed through three windows: the input admittance of the array, the relative currents on the parasitic elements, and the radiation patterns. It is found that resonance - at which the conductance becomes very large and the susceptance very small - does occur. The experiment shows that the quality of the resonance, Q($EQ f/$Delta@f), depends strongly on the equality of the spacing between the elements and good conductive contact between the monopoles and the ground plate.!
