The simulation with high frequency structure simulator (HFSS) three dimensional analyses are presented, also the influence of the feeding transitions for circuit design is studied. The aim of this work was to study the influence of the width of the NRD waveguide to scattering parameters.展开更多

The rule of the theoretical selection of its parameters, if NRD-guide is used as the UWB antennas, is studied firstly, then the radiation characteristics for an open-ended NRD-guide are calculated by FDTD (finite-difference time-domain) method.展开更多
