| Abstract(in English) | A two-beam slotted leaky waveguide array for mobile reception of dual polarization DBS is realized in single layer structure. Two feed waveguides attached at both ends of cross-slotted radiating waveguides excite the leaky waves propagating in opposite directions. Each of them radiates either of two circularly-polarized waves in symmetrical beam directions. Balanced design of two beams for each polarization imposes symmetry in the array design of slots. The slot coupling distribution is optimized for the maximum gain under this symmetry condition. A model antenna in about 300 mm square is fabricated for experiments in 12 GHz band. Antenna efficiency of 71% and 64% are obtained for each beam in different polarizations. |
