Helix Antennas

Discovered by scientist Krauss in 1946, helix antenna is used in space applications, radar systems etc. Usually, it is manufactured as a wire, coiled around dielectric cylinder. It produces circular polarization of emitted EM wave.

This application note encompasses comparing simulation times, number of unknowns and radiation patterns for three simulated helix antennas: wire helix, thin strip helix and thin strip with the dielectric mast. In WIPL-D software, various helix antennas can be successfully designed using powerful built-in object named Helix.

The simulations were carried on regular desktop PC, with extremely low number of unknowns and simulation times measured in seconds. This allows fast tuning, sweep or optimization of the antenna otherwise known for the demanding synthesis process.
