Abstract

A dual grounded internal antenna ( 110 ) is described herein. The dual grounded internal antenna ( 110 ) may include a first ground plane ( 210 ), a second ground plane ( 220 ), and a radiating element ( 230 ). The second ground plane ( 220 ) may be operatively coupled to the first ground plane ( 210 ) via a first connection ( 242 ). The radiating element ( 230 ) may be operatively coupled to the first ground plane ( 210 ) via a second connection ( 244 ). Further, the radiating element ( 230 ) may be operatively coupled to the second ground plane ( 220 ) via a third connection ( 246 ).
