Abstract

In this paper, a Pickett Potter horn antenna is designed and analyzed for Ka band operation. The dimensions of horn are optimized so that the cross polarization level is minimized for the operating frequency range. The design and optimization is done based on theoretical analysis of dual mode horn antennas and computer simulation. The copolarization and the cross polarization radiation pattern of the designed horn are analyzed at 32 GHz. The S₁₁ parameter of the horn antenna for operating frequency range is obtained from simulation. Finally, maximum cross polarization level of the designed horn for Ka band frequencies is analyzed using theoretical analysis and simulation.
