It is shown that since there is no need for an electrical connection between the top and bottom sections of a gap waveguide (GWG), if a sectoral horn is properly designed and realized using this ...

In this paper, a novel broadband high-selectivity stacked filtering antenna with multiple radiation nulls is proposed. The antenna consists of a short-circuited stepped impedance feeding line and two ...

Abstract: This article proposes a comprehensive calculation method for determining the radiation pattern of a conformal circularly polarized antenna array ... radiation patterns for circular ...
