ERI has engineered two broadband element models to be used as building blocks in the construction of custom horizontal radiation patterns. The 1180 Flat Panel and the 1183 Iris Cavity both utilize the 1180 pressurized balun support stems with crossed, dipole arms. The arms may be straight or bent as necessary to meet pattern requirements. These radiators are then mounted in cavities, or on flat reflecting panels and fed using a broadband hybrid feed harness. A wide range of radiation patterns, using multiple elements mounted on either triangular, round or square cross section structures can be achieved. The versatility of pattern shaping is demonstrated in the following horizontal plane relative field patterns. All custom patterns proposed using our 1180 elements are verified and certified using our modern 70 acre test range.
