The main objective of this paper is to focus on the designing of helical antenna in the High Frequency (HF) range from 3 MHz to 30 MHz. Several parameters dimension and helical's profiles were.
Helical antennas have been known for more than half a century, but it seems that reliable design data for helical antennas do not exist in the open literature. This paper points out some inaccurate data about helical antennas, and presents a new set of data related to the optimum design of helical antennas. The antenna's performance is optimized by varying the antenna's geometrical parameters.This paper points out some inaccurate data about helical antennas and presents a new set of data related to the optimal design of helical antennas. The antenna performance is optimized by varying antenna’s.In helical antenna mostly Metal wires are used. These are generally used as the radiator of helical antenna. helical antenna results like - Gain can be determined by the helical coil number namely the longer helical wire is the higher gain of.

Axial mode helical antennas have been used in satellite communication for a long time offering the advantage of a high gain in axial direction over a wide range of frequencies (1). The concept of this antenna was established by Kraus (1), who also developed empirical rules for its design. It is well known that we can enhance the power gain in helical antenna by increasing the number of helical.Read More
A new low-profile variable pitch angle cylindrical helical antenna employing a copper strip as impedance transformer is proposed in this paper. Under the circumstance of a limited antenna height, the circular polarization performance of the antenna has been enhanced by changing the pitch angle and the input impedance matching has been improved by adjusting the copper strip match stub.Read More
In this paper, a novel resonant quadrifilar helical antenna for satellite communication application is presented. The antenna behaves wide beamwidth, circular polarization and high gain. Numerical simulations show that the two short arms are main factors which influence the gain of this kind of antenna.Read More
