This tool converts antenna frequency to its physical length.
Calculator
Enter the frequency of operation and the type of antenna (using the drop down menu)
Formula
λ = c/f
where, c is the speed of light and f is the frequency.
The wavelength can also be scaled down depending on the antenna dimension where the default scaling is 1 for a Full-Wave antenna.
Background
The antenna is a critical component of any wireless system. It converts electrical signals from the transmitter into electromagnetic waves that can be propagated through the air. At the receiver it converts captured waves to a signal voltage that can be processed by the receiver.
The frequency of the signal determines the wavelength, and the antenna must be designed to radiate efficiently at that size.
Application Examples
Use this tool to calculate the spacing between two antennas in a diversity application. For example at 434 MHz, a minimum of ½ wavelength separation is calculated to be 34.5 cm.
