Abstract
PURPOSE:To attain high performance for elliptic polarization rate by constituting exclusive circularly polarized wave circuit systems for a reception system comprising a balanced polarizer, a differential phase shifter and a synthesizer and for a transmission system comprising a circularly polarized wave generator, a circular waveguide and a rotary joint respectively. CONSTITUTION:The reception system uses the balanced polarizer 3a, the differential phase shifter 10, and the synthesizer 11 and the transmission system uses the circularly polarized wave generator 2a, the rotary joint 6a and the circular waveguide 9 to constitute the exclusive circularly polarized wave circuit system respectively. Thus, it is not required to use a circularly polarized wave generator for both transmission and reception and high performance elliptic polarized wave rate is attained and since the circularly polarized wave generator 2a of the transmission system is provided along the rotary shaft 5, the axial length of the feeding system is decreased and miniaturization is contrived.
