Design of a UWB planar quasi Yagi-Uda antenna on S-C band

This paper puts forward a kind of S-C band planar quasi Yagi-Uda antenna which can be used in phased array radar as a unit. The antenna is a kind of miniaturized ultra wideband antenna. It uses the SMA connector to feed itself, so it´s easy for array forming. Also, the planar quasi Yagi-Uda antenna consulted the experience of wide band planar microstrip antenna, and then reduced its size. In brief, this antenna has very outstanding directional radiation effect and high application value.
