Abstract :
A leaky lens antenna system for short pulse applications is designed, fabricated and characterized. The antenna has very good phase center stability over large bandwidths. The leaky lens antenna is connected to an in-house wavelet generator to transmit 100 ps pulses centered at 57.5 GHz. It is shown that the antenna preserves the reference pulse shape and has very low dispersion.
