DUAL-POLARIZATION SLOT-COUPLED PRINTED ANTENNAS FED BY STRIPLINE

This article presents recent techniques in the field of dual-polarizat ion printed antennas for designing shielded radiating structures with high-quality performances in terms of cross-polarization level and inp ut-port isolation. The use of gridded patches provides a natural solut ion to filtering surface currents and is of key importance in limiting inter-element coupling in arrays. Experimental results obtained on va rious designs tire presented.
