An antenna, a portable electronic device incorporating an antenna and a method of operation are provided to enable both wide and multiple frequency band response. The antenna may include a feeding arm and a parasitic element. The feeding arm may include a conductive loop antenna and a conductive excitation arm portion. The loop antenna portion may extend from a first end that is configured to be grounded to a second end that is configured to be driven by radio frequency circuitry. The excitation arm may be coupled at a first end to the loop antenna portion and extend outwardly therefrom to an open end. The parasitic element may extend from a first end is configured to be grounded to a second end that is open. The parasitic element may extend along opposite sides of the excitation arm portion so as to be coupled thereto. |
