Abstract
A simple, circularly polarised, cavity-backed antenna is described which has a two turn low pitch angle helix feed. The helix is terminated in a strip monopole for improved axial ratio. The antenna is approximately one third of the sire of an equivalent conventional monofilar helix antenna.
