Description

Hui Peng and co-authors stack helical antennas into a three-dimensional array in a 2026 paper. Helical antennas radiate off their ends with circular polarization, prized for satellite and navigation links. That end-fire habit fights flat array layouts: sixteen helices cannot simply tile a plane and point the same way through one feed board.

The design solves the geometry with plumbing. Four subarrays of four helices each plug into a waveguide power splitter built into the substrate, and a twisted vertical transition turns the feed through the third dimension to meet them. The built array centers near eleven gigahertz, with wide matched bandwidth and a strong axial-ratio band for clean circular polarization. Peak gain topped eighteen decibels. Measured results tracked simulations closely, which the authors take as proof the three-dimensional feed trick works for end-fire elements.
