antenna based on the Vivaldi element. Four sequentially rotated Vivaldi antenna elements …

This article presents a design methodology and steps to fabricate a tunable step recovery
diode (SRD)-based Gaussian pulse transmitter for ultra-wideband (UWB) radar systems …

A design of a hybrid Gaussian pulse transmitter using a transistor-based pulse generator
and two pulse-shaping networks, a shorted stub delay circuit and a 90° hybrid coupler, is …

A method to reduce the volume of a circularly polarized Vivaldi-inspired antenna array by
bending radiation arms is proposed in this letter. Two orthogonal Vivaldi elements form a …

A compact ultrawideband (UWB) circularly polarized (CP) slot antenna is proposed with a
methodology for automated reoptimization for packaging with proprietary devices. The slot …

This work validates the ability for in-band full-duplex systems to operate over ultra-wide
