<P>PROBLEM TO BE SOLVED: To provide an antenna which does not need the reconnecting work of the terminal of a branching filter consequently, even when position adjustment is performed by rotating a primary radiator. Ž<P>SOLUTION: A bracket 14 holds the primary radiator 11. The bracket 14 can change the position of the primary radiator 11 in a predetermined direction along with the rotation of the primary radiator 11. One end of a circular polarized wave generator (waveguide) 12 is connected to a polarized wave branching filter 13, another end is connected to the primary radiator 11, respectively. The circular polarized wave generator 12 has a mechanism which does not rotate the polarized wave branching filter 13 even when the primary radiator 11 rotates. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
