    Abstract: A multi-band antenna ( 10 ) includes one or more a loop portions ( 12 ) substantially defining operation in frequency ranges covering between approximately 800 MegaHertz and approximately 1.0 GigaHertz and between approximately 1.8 GigaHertz and approximately 2.0 GigaHertz, a surface plate portion ( 14 ) having a length ( 15 ) substantially defining operation in a frequency range between approximately 1.7 GigaHertz and approximately 1.9 GigaHertz, and a slot ( 16 ) within the surface plate portion having a length ( 17 ) substantially defining operation in a frequency range between 5 and 6 Gigahertz (WLAN). The antenna can further include a resonant stub ( 18 ) having a length ( 19 ) substantially defining operation in a frequency range of approximately 2.4 Gigahertz. The antenna can be a unitary radiating element having a feed element ( 9 ) and a ground port ( 7 ). Operationally, the antenna can function in 6 bands and can be independently tunable in a majority of the 6 bands.
