This article presents some techniques of improving characteristics of planar ultra-wideband antennas based on the tapered slot line. Different antenna openings based on the elliptical taper with additional metal flares, smooth and corrugated bent blades had been studied. Several planar antennas with dimensions of 23 to 12 centimeters have been simulated using electromagnetic simulation software, and then designed, fabricated and tested. Results of computer simulations and measurements of the ultra-wideband antenna characteristics are presented.
