BASE STATION ANTENNAS HAVING LOW COST SHEET METAL CROSS-DIPOLE RADIATING ELEMENTS

A cross-dipole radiating element includes a first dipole radiator that has a first dipole arm assembly that includes a first stalk and a first dipole arm that extends from the first stalk and a second dipole arm assembly that includes a second stalk and a second dipole arm that extends from the second stalk, as well as a second dipole radiator that has a third dipole arm assembly that includes a third stalk and a third dipole arm that extends from the third stalk and a fourth dipole arm assembly that includes a fourth stalk and a fourth dipole arm that extends from the fourth stalk. The first and second stalks form a first microstrip transmission line and the third and fourth stalks form a second microstrip transmission line. The first and second microstrip transmission lines directly feed the respective first and second dipole radiators.
