Dual-orthogonal polarized Vivaldi antenna for ultra wideband applications

This paper presents a design of a dual polarized Vivaldi antenna. The problems that were met during the design of such an antenna are depicted and proper solutions are described. The prototype of the proposed antenna is introduced and finally the full characterization of the dual polarized antenna is given. Since UWB is originally a time domain based technique, a time domain characterization of the antenna is also included.
