Abstract

The design of an UWB matching feed structure was presented. The structure adopted a series-parallel hybrid feed method. In an ideal conditions, the structure could feed for a 200 UWB antenna from a 50 coax without reflection. Experiments based on TEM horns and reflector antenna with the structure were done. The results showed that the performance of the antennas was greatly improved, the radiated field of TEM horn increased up to 15% and the reflector antenna increased up to 27% correspondingly.
