1. An antenna system comprising:
an antenna loop element extending between a first end and a second end;
a first isolated magnetic dipole (IMD) antenna feed element capacitively coupled to the antenna loop element;
a second IMD antenna feed element capacitively coupled to the antenna loop element;
a first tuning element coupled to the first IMD antenna feed element, the first tuning element configured to vary an electrical characteristic at the first MID antenna feed element;
a second tuning element coupled to the second IMD antenna feed element, the second tuning element configured to vary an electrical characteristic at the second BID antenna feed element;
a third tuning element coupled to a ground structure and the first end of the antenna loop element, the third tuning element configured to vary an electrical characteristic at the antenna loop element; and
a fourth tuning element coupled to the ground structure and the second end of the antenna loop element, the fourth tuning element configured to vary the electrical characteristic at the antenna loop element,
wherein the first IMD antenna feed element includes one or more capacitively coupled regions forming at least a portion of capacitive coupling of the first IMD antenna feed element to the antenna loop element, and
wherein the second IMD antenna feed element includes one or more capacitively coupled regions forming at least a portion of capacitively coupling of the second IMD antenna feed element to the antenna loop element.
