アンテナ装置
Document Type and Number:
Japanese Patent JP3813581
Kind Code:
B2
Abstract:
This invention relates to an antenna device having a plurality of reflecting mirrors (1,2) and a primary radiator (3), wherein a main reflection mirror (1) is disposed obliquely upwardly and a sub-reflection mirror (2) is disposed obliquely downwardly, comprising
a first circular waveguide (38a,31a) which is connected to a first primary radiator (3a); a first circular waveguide rotary joint (5a) which is connected to the first circular waveguide (38a,31a); a first orthogonal polarization diplexer (20a) which is connected to the first circular waveguide rotary joint (5a); a second circular waveguide (38b,31b) which is connected to a second primary radiator (3b); a second circular waveguide rotary joint (5b) which is connected to the second circular waveguide (38b,31b); a second orthogonal polarization diplexer (20b) which is connected to the second circular waveguide rotary joint (5b); a first waveguide T-junction (30a) which is connected to said first and second orthogonal polarization diplexers (20a,20b); a second waveguide T-junction (30b) which is connected to said first and second orthogonal polarization diplexers (20a,20b); a third orthogonal polarization diplexer (21) which is connected to said first and second waveguide T-junctions (30a,30b); and a third circular waveguide rotary joint (8) which is connected to the third orthogonal polarization diplexer (21),
whereby said first circular waveguide rotary joint (5) and said third rotary joint (8) are arranged with their rotary axis on an elevation axis (E1) and an azimuth axis (Az), respectively, the elevation axis and the azimuth axis being orthogonal to each other, and whereby said plurality of reflecting mirrors and said primary radiator(s) are designed to rotate together with at least parts of the waveguides and polarization diplexers around the elevation axis and the azimuth axis.
