Design of an Ultrawideband Antipodal Tapered Slot Antenna Using Elliptical Strip Conductors

This letter presents the design of an ultrawideband antipodal tapered slot antenna printed with elliptically shaped strip conductors. A new design equation was empirically determined and used to implement these antennas. The fabricated prototypes were experimentally verified through measurements, and good agreement with simulations was obtained. The measured result of one of the prototypes shows 24:1 bandwidth with good radiation characteristics.
