In this paper, we propose a novel radial line planar phased array in which helical antenna elements are individually rotated by their respective connected micromotors to realize dynamic beam-scanning.

Compact horizontally polarized antennas inspired by W6NBC Above is my first build of a helix antenna described in W6NBC's paper in QST. Roughly speaking it would fit in a 170cm sided cube, and it ...

This paper presents a novel dual-linearly-polarized quadrifilar helix antenna (DLP-QHA) with high cross-polarization discrimination (XPD) and high isolation. The antenna comprises four helical arms, ...
