Abstract: An electronically steerable antenna with dual polarization is provided, as well as a method for steering such an antenna. An example antenna may include a driven patch element having dual polarity for radiating or receiving a first beam with a first polarization and radiating or receiving a second beam with a second polarization. The antenna includes a parasitic patch element separated from the driven patch element and in a parasitic coupling arrangement to the driven patch element, as well as first and second tuning elements linked to the parasitic patch element to control first and second terminating impedances of the parasitic patch element, respectively. The first terminating impedance at least partly determines a direction of the first beam, and the second terminating impedance at least partly determines a direction of the second beam.
