<p>An antenna system includes a main array (62) and a guard array (64). The main array has an antenna pattern that includes a main beam and multiple side lobes that are concentrated in distinct side lobe regions. The guard array includes an antenna pattern that encompasses both the main beam and the side lobe regions of the main array. In addition, an outer boundary of the antenna pattern of the guard array roughly tracks an outer boundary of the distinct side lobe regions of the main array. In at least one embodiment, the main array is a rectangular or quasi-rectangular array having side lobes concentrated within two orthogonal ridges and the guard army comprises one of a cross-guard array, an L-guard array, and a T-guard array.</p> |
