Abstract
An antenna includes a non-conductive pane, a ground plane disposed on the non-conductive pane, and a radiating strip disposed on the non-conductive pane for operating in a plurality of frequency bands. The radiating strip defines a plurality of loops. A portion of a periphery of one of the loops coincides with at least a portion of a periphery of another of the loops. The radiating strip also includes at least one branch extending away from the periphery of one of the loops to allow tuning and shifting of the resonant frequencies of the antenna.
