Center-fed multifilar helix antenna
Abstract
An antenna system including a phasing circuit for producing balanced, phase displaced, signals for connection to an antenna. The antenna comprises, for each set of balanced phase signals, a pair of antenna elements disposed serially along a helical path. A transmission line, connected to each of the phasing circuit terminals, drives each antenna element pair at a center location by being connected to the proximate ends of each pair. The antenna has a omnidirectional radiation pattern, a wide band width, a good front-to-back ratio and can be constructed in a compact form.
