1. Introduction to Horn Antennas

2. Introduction Horn Antennas :
flared waveguides that produce a nearly uniform phase front larger than the waveguide itself
constructed in a variety of shapes such as sectoral E-plane, sectoral H-plane, pyramidal, conical, etc.

3. Application Areas
used as a feed element for large radio astronomy, satellite tracking and communication dishes
A common element of phased arrays
used in the calibration, other high-gain antennas
used for making electromagnetic interference measurements

4. E-plane Sectoral Horn
Fields expressions OVER THE horn are similar to the fields of a TE10 mode for a rectangular waveguide with the aperture dimensions of a and b1.
difference is in the complex exponential term, parabolic phase error,.

9. Pyramidal Horn
combination of the E-plane and H-plane horns and as such is flared in both directions

10. Other horn antenna types
Multimode Horns
Corrugated Horns
Hog Horns
Biconical Horns
Dielectric Loaded Horns
etc.
