Title:

MULTI-BEAM REFLECTION MIRROR ANTENNA DEVICE

Document Type and Number:

Japanese Patent JP2003209434

Kind Code:

A

Abstract:

To provide a multi-beam reflection mirror antenna device in which beam peak distortion caused by the secondary curved mirror of offset arrangement can be compensated.

In the multi-beam reflection mirror antenna device provided with a rotation-symmetric main reflection mirror 1, a rotation-symmetric sub reflection mirror 2, a plurality of reflection mirrors, and a plurality of primary radiators 5, the plurality of reflection mirrors are composed of two secondary curved mirrors 4a and 4b offset and arranged so that their focal points are aligned on one straight line and other two secondary curved mirrors 4a' and 4b' arranged surface-symmetrically to these two secondary curved mirrors.
