Types of Horn Antenna:

• E-plane sectored horn• H-plane sectored horn• Pyramidal horn antenna• Conical horn antenna• Corrugated horn antenna• Exponential horn antenna

Pyramidal Horn Antenna:

Conical Horn Antenna:

Biconical Horn Antenna:

Corrugated Horn Antenna:

Exponential Horn Antenna:

Directivity:

• Directivity of an E-plane sectored horn is:=

• Directivity of an H-plane sectored horn is:

where c(u),c(v),s(u) & s(v) are Fresnel integralsa & b are dimensions of wave guide

Directivity:

• Directivity of a pyramidal horn antenna is:

where D DE= Directivity of an E-plane

sectored horn a & b are dimensions of wave guide

Applications of horn antenna:• In satellite

communication• In TV base station
