Abstract: This paper proposes a fractional observer-based sliding-mode control for a generalized nα -differentiator with the aim of achieving closed-loop asymptotic stability. The proposed methodology ...

This paper presents a circular-polarized gap-waveguide-based compact monopulse array antenna for millimeter-wave tracking applications at Ka-band (29 to 31 GHz). The gap waveguide planar monopulse ...
