Abstract
An antenna system. The system includes a feed network with first input/output terminals and second output/input terminals, and antenna elements forming an array. In a first configuration: each of the second plurality of output/input terminals is connected to one of the antenna elements, the array operating according to a different radiation pattern based on which one of the first plurality of input/output terminals carries a signal into the feed network. In a second configuration: a selected antenna element is disconnected from the second plurality of output/input terminals and receives a direct signal, bypassing the feed network, and operates according to its independent radiation pattern. Also, in the second configuration each remaining antenna element is disconnected from the second plurality of output/input terminals and connected directly to a detuning network, causing these antenna elements to have a minimal effect on the independent radiation pattern of the selected antenna element.
