【Abstract】 The design principle of the circularly cylindrical conformal slotarray feeded by the couplings with the circularly curved waveguide is given. The calculations of coupling slots between the curved waveguide and the fan shaped straight waveguides are emphasized. The coupling slots control the strengths of excitations of the radiating waveguides and compensate the phase differences due to the different lengths of rays from each slot located at the cylindrical surface. The Dyadic Green’s functions in the curved waveguide are obtained from the field equations directely.更多还原
