Antenna Element Catalog

Horn antennas come under the classification of aperture antennas. And are most commonly used at microwave frequencies. Such antennas are used in space applications. Horn antennas are used as feeding elements for large radio astronomy, satellite tracking, and communication dishes. These antennas are also used in phase array applications.

Model, Analyze and Compare Horn Antennas

Model, analyze the pattern and compare the gains of different types of horn antennas. Horn antennas are essentially a section of a waveguide where the open end is flared to provide a transition to the areas of free space. This antenna is a simple development of a waveguide transmission line. It is possible to leave a waveguide open and let signal radiate, but this is not efficient. Signals passing along the waveguide see a sudden transition from the waveguide to free space, which cause the signals to be reflected back along the waveguide as standing waves. To overcome this issue the waveguide can be tapered out or flared, for providing a gradual transition from the impedance of the waveguide to that of free space.
