Abstract

An antenna array includes a first patch antenna and a second patch antenna which are oriented mutually in parallel. Each patch antenna includes a linear array of radiation elements. Adjacent radiation elements within each patch antenna are equidistantly spaced apart and are interconnected. In addition, a connecting line between adjacent first ends of the two patch antennas is provided, and the two second ends of the patch antennas are each adapted for transfer of an electrical oscillation. The spacings between the adjacent radiation elements of the first patch antenna are greater than the spacings between the adjacent radiation elements of the second patch antenna.
