摘要: As to low observable platform, one of the major contributing sources target RCS is scattering due onboard antennas. So research on reduction antenna important. In this paper, a holly-leaf-shaped monopole with designed. A square notch etched improve impedance matching and expand bandwidth in ground. The measured i10dB from 2.1 15.4GHz (only little higher than around 7.5GHz). radiation patterns retain symmetry are relatively stable at 2.5, 8 11GHz. monostatic performance four difierent incident cases studied obtain some helpful conclusions for UWB antenna. achieves efiective comparison that reference largest 4.1, 19.8, 3.9dBsm three cases, respectively, while loss gain only about i1:3dB. suits occasion desiring RCS.
