Abstract Two new configurations of patch antennas are introduced, which provide dual‐band and dual‐polarization operations. The two patches have a square and cross shape, and are printed on a single layer; the dual‐frequency and the dual‐polarization behavior is obtained by means of four narrow slots close to the edges. Excellent decoupling between the two orthogonal modes at each frequency is obtained in both configurations. Furthermore, a satisfactory performance of simultaneous matching when using a single feed point is demonstrated. Simple and accurate design formulas to predict the two resonant frequencies are derived on the basis of a physical model and tested by using a full‐wave analysis. Some prototypes have been carried out and measured.
