Horn Antenna Equation

Horn antennas are used for directional transmission and reception of electromagnetic waves. They are a type of aperture antenna, where the electromagnetic fields pass through the antenna’s aperture. The aperture can be rectangular or circular. Horn antennas are frequently used as feeds in Cassegrain antennas.

The following equation or formula is used for the Horn Antenna calculator:

Horn antennas are popular above 1 GHz because they are easy to construct and offer high gain, low VSWR (Voltage Standing Wave Ratio), and a wide bandwidth.
