Instead, the electromagnetic spectrum has emerged as the decisive operational domain—an arena where radar deception, ...

The article presents a dual shaped helical antenna with optimized geometry for phased array applications. The use of a directive element in steered phased arrays lets the separation between radiators ...

In this paper, we designed a broadband and wide-beam quadrifilar helix antenna (QHA). By loading a ceramic dielectric ring around the QHA, the beamwidth is sign ...
