Wireless device and antenna system with extended bandwidth
An apparatus comprises an antenna element operable in multiple frequency bands and configured to be connected to a ground plane and to a radiofrequency system to provide impedance matching at the multiple frequency bands, where the radiofrequency system comprising at least a matching network. A maximum length of the antenna element is shorter than L/12 but longer than L/22, where L is the free-space wavelength corresponding to a lowest frequency related to a lowest frequency region of operation of the antenna element. A contour of the antenna element has a complexity factor F12 less than 1.25.
