    In recent years, there has been an increasing interest in dual linear polarization antennas for various purposes, e.g. polarimetric synthetic aperture radar (SAR) imaging. A key design goal for dual polarization antennas is to obtain a high cross-polarization suppression. When using standard techniques for improving the cross-polarization suppression in dual linear polarization antenna arrays undesired sidelobes appear. This paper describes the properties of some known cross-polarization suppression methods and presents a new method for obtaining high cross-polarization suppression and simultaneously avoiding undesired sidelobes
