Abstract
An antenna ( ) having a plurality of unitary dipole antennas ( ) formed by folding a stamped piece of sheet metal. Each of the unitary dipole antennas ( ) are fed by two stripline feed systems ( ). Each of these feed systems are separated above and extend over a groundplane ( ) and are separated by an air dielectric to minimize intermodulation (IM). Phase shifters ( ) in combination with a downtilt control lever ( ) are slidably adjusted beneath the respective dividing portions of the stripline feed system to adjust signal phase and achieve a uniform beam tilt having uniform and balanced side lobes. These stripline feed systems can also be formed from stamped sheet metal and which have distal ends bent 90° upward to couple to the respective dipole antennas ( ).
