Abstract
A multiple-beam antenna is provided which is capable of receiving radio waves from two satellites by one down converter and readily adjusting a polarization displacement due to a locational difference in receiving areas. Probes for vertically and horizontally polarized waves are inserted to two circular waveguides corresponding to signals from two satellites. One end of each probe is bent to have an angle for adjustment of the polarization displacement where it is installed. The other end of each probe is mounted on a board of a down converter via a through hole.
