Simulation Analysis of Cross Polarization Property of Waveguide Slot

Cross polarization is the inherent property of waveguide slot antenna. The usual suppression measures decrease its influence, but these don't consider how to utilize this intrinsic property, for example cross polarization of mono-pulse antenna can be used for producing interference, so it is necessary to research the cross polarization property. Based on the polarization property of sidewall slot, the cross polarization principle is analyzed, and the property is simulated in different conditions. Good agreement of the theory with results, and these have great benefit to the utilization of waveguide slot antenna. This study provides an important theoretical basis for ECM and ECCM technology studies in mono-pulse tracking area.
