Title: Antenna system
Inventor: FURUNO TAKAMASA
IPC: H04J11/00
Filed: 1987-12-26
Abstract: PURPOSE:To obtain a superior cross polarization identification characteristic extending over a wide range by inserting a waveguide operated rotatably within a dedicated band area and whose cross-section is formed in elliptical shape to a group branching filter. CONSTITUTION:The waveguide operated rotatably centering a pipe shaft and whose cross-section is formed in the elliptical shape is inserted between the group branching filter 8b which branches the fHGHz of a reception antenna system and the group branching filter 9b which branches the fLGHz. And the elliptical polarization ratio of the waveguide is set larger than that of an elliptical waveguide 7b connected between the group branching filter 8b dedicated for fHGHz and a circular feed waveguide 6b. Therefore, the wave of the elliptically polarized wave on a fLGHz zone is also converted to a linearly polarized wave by an elliptical waveguide 11, and is fed to the group branching filter for fLGHz zone. Thus, since plural elliptical waveguides with different elliptical polarization ratio are used at every frequency band area, it is possible to obtain the superior cross polarization identification characteristic extending over the wide range.
