专利名称：VIVALDI ANTENNA 发明人：FISHER, James Joseph 申请号：EP02796272.9 申请日：20020822 公开号：EP 14 8B 1 公开日：20060104
摘要：There is provided a directional, wideband, planar antenna arrangement. The antenna arrangement is a class of Vivaldi aerial constructed as a plurality of conductive layers disposed on at least one substrate layer. The conductive layers are arranged to form a flared notch. The flared notch widens from a closed end to an open end. Instead of conforming to a simple exponential flare-shape, the inventive flared notch is arranged to conform to a hybrid curve. The hybrid curve comprises a plurality of self-similar curve sections. As the flare widens, each successive curve section is scaled up by a scaling factor and joined at its wider end with a neighbouring curve section. The antenna arrangement thereby becomes operable over a far wider frequency range than the conventional Vivaldi aerial. The hybrid flared notch can also be implemented in antipodal and balanced antipodal Vivaldi aerials.
