| Abstract: | The parabolic antenna fed with half-wave dipole, with circular disc short-focus parabolic reflector was studied. The meaning of low sidelobe antenna was briefly introduced. The radiation characteristics of feed source of the antenna was theoretically analyzed and electromagnetically simulated. A low sidelobe parabolic antenna was designed which was low cost, small size, simple structure, and good electrical properties. It can be applied to special occasions as life detection radar systems in need of low-cost and smallsize. |

| Keywords: | low sidelobe short-focus parabolic reflector half-wave dipole utilization coefficient of aperture field |
