Abstract
A variable gain horn and a system for testing an antenna with the variable gain horn is disclosed. The variable gain horn includes a horn adapted to transmit electromagnetic signals to an antenna under test. The horn is adapted to have a diverging lens attached and detached without fasteners at its distal end of the horn by a form fit. When the diverging lens is not attached, the variable gain horn transmit the electromagnetic signals at a higher directivity than when the variable gain horn with the diverging lens attached to the distal end. The system also comprises a parabolic mirror adapted to reflect the electromagnetic signals incident thereon from the variable gain horn to an antenna under test (AUT).

A variable gain horn, comprising:
- a horn adapted to transmit electromagnetic signals to an antenna under test, the horn comprising a proximal end adapted to receive the electromagnetic signals and a distal end adapted to transmit the electromagnetic signals;
- and
- a diverging lens adapted to be attached to the distal end of the horn by a form fit, wherein when the diverging lens is not disposed at the distal end of the horn, the variable gain horn without the diverging lens attached to the distal end transmits the electromagnetic signals at a higher directivity than when the variable gain horn with the diverging lens attached to the distal end.
A system for testing antennae, the system comprising:
- a variable gain horn, comprising:
- a horn adapted to transmit electromagnetic signals to an antenna under test (AUT), the horn comprising a proximal end adapted to receive the electromagnetic signals and a distal end adapted to transmit the electromagnetic signals;
- and a diverging lens adapted to be attached to the distal end of the horn by a form fit, wherein when the diverging lens is not disposed at the distal end of the horn, the variable gain horn without the diverging lens attached to the distal end transmits the electromagnetic signals at a higher directivity than the variable gain horn with the diverging lens attached to the distal end;
- a parabolic mirror adapted to reflect the electromagnetic signals incident thereon from the variable gain horn to AUT.
