Abstract: A novel approach to computing millimeter-wave reflectors is proposed. In this approach, the computational model is created by means of the axisymmetry property and the MoM based on the bodies of revolution is used to analyze this model. To reduce the number of unknown quantities, the hybrid base functions are used, i.e., the entire-domain base functions are applied in the main reflector with a flat geometry, and sub-domain base functions in the complex feed source region. Computational results are compared with those obtained by the full-wave MOM and experiment. It is shown that the numerical results are in good agreement with the results obtained by the full-wave MOM and the measured data, and supports a new way to design high-performance microwave transmission antennas.

Key words: MoM of bodies of revolution, hybrid base functions, millimeter-wave antennas
