A wideband antenna array including a plurality of antenna element cards. In certain embodiments the cards include a plurality of first radiators and a plurality of second radiators. The first radiators operate in a low band portion of the array's operating spectrum, and the second radiators operate in a high-band portion of the array's operating spectrum. In certain other embodiments at least one of the cards includes a pair of radiators. The radiators in the pair are oriented in substantially opposite directions. In certain other embodiments a first plurality of the antenna element cards includes at least a first radiator, a second radiator and electronics for controlling both the first and second radiators. A second plurality of the antenna element cards includes at least a first radiator, a second radiator and electronics for controlling only one of the first and second radiators.
