Helix Antennas
A helix is a broadband antenna and used with a ground plane. This antenna is used in satellite communication devices such as telephones radio and global positioning systems (GPS).
The dipoleHelix antenna supports AI-based tuning and
analysis. For more details, see design and AIAntenna documentation.

Helical Antenna Design
Studies a helical antenna designed in [2] with regard to the achieved directivity. Helical antennas were introduced in 1947 [1]. Since then, they have been widely used in certain applications such as mobile and satellite communications. Helical antennas are commonly used in an axial mode of operation which occurs when the circumference of the helix is comparable to the wavelength of operation. In this mode, the helical antenna has the maximum directivity along its axis and radiates a circularly-polarized wave.
Analyze Metal Conductors in Helical Dipole Antenna
Design helical dipole antennas using different conductors and analyze their characteristics as functions of the conductor thickness and conductivity.
