technical seminar on helical antenna
Post: #2
A helical antenna is an antenna consisting of a conductive wire wound in the shape of a helix. In most cases, helical antennas are mounted on a ground plane. The power line is connected between the lower part of the propeller and the ground plane. Helical antennas can operate in one of two main modes: normal mode or axial mode.

In normal mode or lateral helical antenna, the diameter and pitch of the antenna are small compared to the wavelength. The antenna acts similarly to an electrically short dipole or monopole, and the radiation pattern, similar to these antennas, is omnidirectional, with maximum radiation at right angles to the axis of the helix. The radiation is polarized linearly parallel to the axis of the helix. These are used for compact antennas for portable and mobile two-way radios, and for UHF television transmission antennas.

In the helical axial or axial fire helical antenna, the diameter and pitch of the helix are comparable to a wavelength. The antenna works like a directional antenna that radiates a beam outside the ends of the helix, along the axis of the antenna. Radiate circularly polarized radio waves. These are used for satellite communication.
