Abstract
The invention concerns a method and apparatus for reducing mutual coupling among adjacent planar antenna radiating elements in an array. The elements can be positioned adjacent to one another in a standard geometric array configuration. A circumferential conductive metal line is provided in the plane of each element at an outer perimeter thereof. The conductive metal line is electrically connected to a ground potential. The ground plane potential is preferably provided by a ground plane reflector over which the antenna elements are suspended. The conductive metal line can be connected to the ground plane reflector by one or more ground posts extending between the conductive metal line and the ground plane reflector.
