PROBLEM TO BE SOLVED: To provide a satellite broadcast receiving converter which receives left-handed and right-handed polarized radio waves each transmitted from two adjacent satellites and is improved in degree of freedom of circuit design, ensuring the isolation of isolating vertically polarized radio waves from horizontally polarized radio waves. SOLUTION: A first fine radiation pattern 32a and a second fine radiation patterns 32b which are arranged so as to form an electrical angle of 45 deg. with the axes of vertical polarization first probes 30a and 31a, and horizontal polarization second probes 30b and 31b respectively are formed on a first circuit board 6, the first fine radiation pattern 32a is made to cross the phase conversion part 12 of a first dielectric feeder 3 nearly at right angles, and the second fine radiation pattern 32b is extended in parallel with the phase conversion part 16 of a second dielectric feeder 4. The phase conversion part 12 of the first dielectric feeder 3 is set longer than the phase conversion part 16 of the second dielectric feeder 4. |
