Abstract: Based on the analysis and design of compact corrugated horn by using the mode matching method and spherical wave expansion,the tolerancing analysis of compact corrugated horn is presented for the first time in the paper,and taking the on board compact corrugated horn for an example.The paper gives the effect of tolerances of design parameters on the cross polarization and return loss of compact corrugated horn and provides the important criteria for designing compact corrugated horn.
