STEERABLE BEAM HELIX ANTENNA

摘要

A variable helix antenna consisting of one or more conductors (35, 36) affixed to a furled dielectric sheet (30). The antenna beam being steerable by furling and unfurling of the dielectric sheet either rotationally, axially or by a combination of both. Multiple interleaved dielectric sheets may be used for multifilar embodiments and matching and compensation elements may also be provided on the dielectric sheet.
