Frequently Asked Questions

How is dipole antenna calculated?

The calculation of a dipole antenna involves determining its length based on the desired operating frequency. The formula for calculating the length of a dipole antenna is: L = 0.5 λ, where L is the length of the dipole antenna and λ is the wavelength of the radio signal. To find the wavelength of the signal, you can use the formula: λ = c/f, where λ is the wavelength, c is the speed of light (approximately 3 x 10^8 meters per second), and f is the frequency of the signal in Hertz (Hz). Once you have determined the wavelength of the signal, you can calculate the length of the dipole antenna using the first formula.

What is the formula for dipole antenna length?

The formula for the length of a dipole antenna is: L = (λ/2) * VF, where L is the length of the antenna, λ is the wavelength of the signal in the antenna's operating frequency, and VF is the velocity factor of the antenna's material.

What is a dipole antenna?

A dipole antenna is a type of radio antenna that is made up of two conductive elements of equal length, oriented in parallel and spaced apart from each other. The conductive elements are usually made of metal and are fed by a single transmission line in the center, with each element connected to one of the transmission line's conductors.

How many ohms is a dipole antenna?

The impedance of a dipole antenna depends on various factors such as its length, operating frequency, and the environment in which it is installed. In free space, a half-wavelength dipole antenna has an impedance of approximately 73 ohms, which is purely resistive. This value is known as the dipole's "radiation resistance"
