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 ...

QS RF Locator is Danish Quadsat's new drone-based product that can geolocate RF signals to a precise location.

Pyramidal E-plane horn antennas with a small size are introduced as the radiating ... prototypes consisting of 64 and 256 radiating elements, respectively. Stable radiation patterns with low cross ...

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 ...

8 isotropic elements Uniform spacing of 0.5 wavelengths No beam steering (broadside pattern) Visualizes the array’s radiation pattern in 2D ...
