Low sidelobe antenna system employing plural spaced feeds with amplitude control
 Various antenna systems are disclosed which generate a shaped beam having a substantially Gaussian distribution substantially without sidelobes. The antenna system consists of basic subarrays consisting of seven or nine radiating elements arranged respectively in a circle with a central element or in the form of a square. The radiating elements are fed in phase but the power applied to each element and the spacing is so selected that due to interference the sidelobes substantially disappear. More complex antenna arrays to form different beam shapes may be formed from the two basic subarrays.
