Abstract :
The ultrawideband (UWB) performance and impulse response parameters of tapered slot antennas with different flare´s opening rates and taper types fit to a stepped quarter-wave Chebyshev transformer are presented. This transformer is used to maximize the impedance bandwidth and power transfer gain. Different smoothing tapers are used to optimize impulse response parameters. The antennas were designed for 1-3 GHz frequency range, and the substrate is Duroid with a dielectric constant 6.15.
