Abstract A simple but reliable two-layer model of the waveguide structure was introduced to replace a real, complex four-layer model in the design of Radial Line Slot Antenna (RLSA) for satellite on board antenna in 32GHz band. Fidelity of this equivalent model was examined experimentally by several test antennas. A fast analysis method using the Method of Moment (MoM) was also applied on the equivalent model to estimate the antenna performance. Finally, an RLSA having φ = 900mm diameter was fabricated and characterized by the near field measurement. A directivity of 48.3dBi correspond to 73% aperture efficiency was obtained at 31.9GHz.
