Beam Width between First Null (BWFN) of Helical Antenna

LaTeX Go Helical Beam Width of First Null Broadside Array = 115*Helix Circumference^(3/2)/(Operational Circumference*sqrt(Turn Spacing*Number of Turns of Helical Antenna))

Gain of Helical Antenna

LaTeX Go Helical Antenna Gain = 11.8+10*log10(Helix Circumference^2*Number of Turns of Helical Antenna*Turn Spacing)

Helix Circumference of Helical Antenna

LaTeX Go Helix Circumference = Input Impedance/140

Input Impedance of Helical Antenna

LaTeX Go Input Impedance = 140*Helix Circumference

Axial Ratio of Helical Antenna Formula

LaTeX Go

Axial Ratio = ((2*Number of Turns of Helical Antenna)+1)/(2*Number of Turns of Helical Antenna)
AR = ((2*n)+1)/(2*n)

What is axial mode for helical antenna?

In the axial mode of radiation, the radiation is in the end-fire direction along the helical axis and the waves are circular or nearly circular polarized waves. This mode of operation is obtained by raising the circumference to the order of one wavelength and a turn spacing of approximately λ/4.

How to Calculate Axial Ratio of Helical Antenna?

Axial Ratio of Helical Antenna calculator uses Axial Ratio = ((2*Number of Turns of Helical Antenna)+1)/(2*Number of Turns of Helical Antenna) to calculate the Axial Ratio, The Axial Ratio of Helical antenna is the ratio between the major and minor axis of a circularly polarized antenna pattern. For an antenna to have perfect circular polarization, the Axial ratio would be close to 1. Axial Ratio is denoted by AR symbol.

How to calculate Axial Ratio of Helical Antenna using this online calculator? To use this online calculator for Axial Ratio of Helical Antenna, enter Number of Turns of Helical Antenna (n) and hit the calculate button. Here is how the Axial Ratio of Helical Antenna calculation can be explained with given input values -> 1.083195 = ((2*6.01)+1)/(2*6.01).

FAQ

What is Axial Ratio of Helical Antenna?

The Axial Ratio of Helical antenna is the ratio between the major and minor axis of a circularly polarized antenna pattern. For an antenna to have perfect circular polarization, the Axial ratio would be close to 1 and is represented as AR = ((2*n)+1)/(2*n) or Axial Ratio = ((2*Number of Turns of Helical Antenna)+1)/(2*Number of Turns of Helical Antenna). Number Of Turns Of Helical Antenna is the number of identical parallel antennas are arranged along a line.

How to calculate Axial Ratio of Helical Antenna?
